Description

Technical Field

[0001] The present invention relates to the technical field of energy conservation and environmental protection, and in particular to a composite thermal insulation material, an energy-saving and environmentally friendly wall, a preparation method thereof, and special production equipment. Background Art

[0002] In recent years, building reflective thermal insulation coatings have been widely used as a new type of functional building coatings in areas with hot summers and warm winters, and hot summers and cold winters. In areas with hot summers and cold winters, on the exterior walls of some special buildings, such as energy-saving blocks that do not require an exterior wall insulation system (such as core-hole inserted insulation board concrete blocks, aerated concrete blocks, etc.), they are used in conjunction with thermal insulation putty to form a building reflective thermal insulation coating-insulation putty system, which can not only meet the building energy-saving design requirements, but also to a certain extent play the role of reducing the wall surface temperature and preventing cracking in summer, achieving good application effects. When applied on masonry walls with good energy-saving effects, the matching inorganic thermal insulation mortar has poor performance, poor physical and mechanical properties, or poor economic performance. The poor application effect of inorganic thermal insulation mortar is a direct obstacle to the application of building reflective thermal insulation coatings. In addition, with the continuous advancement of building energy conservation, higher requirements are placed on building energy conservation work. Most of the existing coatings used on the exterior surfaces of buildings are not environmentally friendly and contain a large amount of radiant heat-conducting substances. After use, this type of coating that cannot reflect light and heat will absorb a large amount of heat and transfer it to the wall through heat conduction. After the wall becomes hot, the indoor temperature will rise, which will greatly increase the use time of the air conditioner. As we all know, Freon is added during the use of the air conditioner. Freon is a substance that destroys the atmosphere and is not conducive to environmental protection. Secondly, after absorbing heat, due to the large temperature difference between day and night, thermal expansion and contraction will form, and the coating on the exterior surface of the building may crack and peel, affecting the appearance and the ability to resist stains will also deteriorate. Rainwater will accumulate in the cracked areas of the coating, thereby breeding bacteria. Not only will the surface of the building become black, but the thermal insulation effect of the coating will be limited, and the stability of the coating will be poor.

[0003] In addition, with the development of science and technology, people's functional requirements for walls are gradually increasing. In addition to the general strength requirements for wall materials, there is also an increase in the demand for practical functions such as thermal insulation and fire prevention. With the development of smart sensors and artificial intelligence control, energy-saving curtain walls that can perform ecological temperature control have also emerged. The emergence of these walls not only meets the market's diverse needs for walls, but also further expands the field of wall materials. In terms of the functionality of wall materials, the most widely used are usually energy saving, thermal insulation and fire prevention. The glass wool and rock wool used in the external thermal insulation of buildings on the market currently have poor thermal insulation performance and are prone to produce toxic substances. Therefore, traditional external thermal insulation decoration methods on the market generally have poor thermal insulation performance or fire prevention functions. Therefore, new wall materials usually use PC plastic resin, diatomaceous earth, nano-aluminate, etc. to prepare wall materials. This type of wall material not only has excellent fire prevention functions, but also has energy-saving and thermal insulation effects. However, in the preparation process of new fire-proof, energy-saving and heat-insulating wall materials, in order to improve the quality of raw material mixing in the preparation process of wall materials, the prepared wall materials have smaller pores, higher pore distribution density and higher compressive performance. The raw material mixing of the wall materials needs to be added multiple times and stirred repeatedly. During this period, the stirred materials need to be cooled or heated. For example, new materials are added after cooling to room temperature, and the temperature is increased to improve the mixing effect. The realization of the above functions generally involves temperature control of the mixing tank through a temperature control system. The temperature in the mixing tank is currently controlled by steam, thermal oil, electric heating, circulating water, etc., but this method will increase the energy consumption of the mixing equipment during operation, resulting in an increase in production costs and an increase in resource loss. Moreover, the stirring speed of the raw material stirring is usually pre-set according to industry experience and cannot be adaptively adjusted according to the stirring effect. As a result, due to factors such as equipment quality and production environment, the stirring effect of the raw materials may be poor, and the raw materials cannot be fully mixed, thereby affecting the energy-saving and heat-insulating effects of the wall materials. Summary of the Invention

[0012] Improved construction performance: The use of additives such as cellulose methyl ether and sodium lignin sulfonate improves the construction performance of wall materials, making them easier to apply and scrape, reducing construction difficulty and improving construction efficiency.

[0013] Regulating indoor humidity: The microporous structure of diatomaceous earth can absorb and release moisture, which can regulate indoor humidity to a certain extent and improve living comfort.

[0014] A method for preparing an energy-saving and environmentally friendly wall comprises the following steps:

[0015] (1) Raw material preparation: The wall material includes the following raw materials in parts by weight: 30 parts of diatomaceous earth; 20 parts of zirconium anhydride ceramic microbeads; 10 parts of PC plastic resin; 5 parts of nano-aluminate; 10 parts of calcined magnesia; 3 parts of polypropylene fiber; 2 parts of cellulose methyl ether; 3 parts of sodium lignin sulfonate; 2 parts of zirconium coupling agent; 10 parts of expanded perlite; 5 parts of aerogel; the diatomaceous earth, nano-aluminate, calcined magnesia, and expanded perlite are pre-dispersed;

The stirring speed is adaptively adjusted according to the temperature change of the raw materials, and the stirring time is about 15-20 minutes. Under the continuous stirring state, the pre-dispersed diatomaceous earth suspension or dispersion is slowly added to the special production equipment, and the stirring is continued for 10-15 minutes to fully mix the diatomaceous earth with other materials. Finally, the polypropylene fiber is added to the special production equipment for energy-saving and environmentally friendly walls, and a zirconium coupling agent is added at the same time. The stirring speed is adaptively adjusted according to the temperature change of the raw materials during the stirring process, and the stirring is continued for 10-15 minutes to evenly distribute the polypropylene fiber in the material, and the zirconium coupling agent is used to improve the bonding strength between the components.

[0017] (3) Molding: Place the fully mixed wall material into the mold and select the appropriate mold shape and size according to actual needs;

[0018] (4) Quality inspection: Conduct quality inspection on the prepared wall materials, including appearance inspection, size measurement, density measurement, thermal conductivity test, compressive strength test, etc., to ensure that the performance indicators of the materials meet the design requirements; finally, combine with composite insulation materials to produce the finished product.

[0019] The method for adaptively adjusting the stirring speed is:

[0020] (1) Determine basic parameters; determine the basic stirring speed setting value v0 and the weight adjustment coefficient α, where α is a suitable value determined through experiments or experience;

[0021] (2) Setting temperature sensors; multiple temperature sensors are set in the stirring container of the special production equipment to obtain temperature data at different positions in real time. The number and position of the sensors should be reasonably arranged according to the shape, size and characteristics of the stirring process of the stirring container to ensure that the temperature distribution in the stirring system can be fully and accurately reflected. The temperature sensor collects temperature data in real time and transmits the data to the control system for processing.

This expression measures the degree of isolation by calculating the temperature difference between the point and the surrounding points and the inverse of the spatial distance. The greater the temperature difference and the closer the spatial distance, the higher the isolation index; the adjustment calculation based on the temperature change trend is:

[0027] The intensity is represented by the coefficient I jk Multiplying with the final global isolation index to obtain the salient feature selection weight

[0028] W jk =I jk ×G jk ×G′ jk ;

[0029] (3) Calculation of stirring speed expression: Assuming there are m temperature detection points and each detection point has n data points, the expression of stirring speed v can be expressed as:

[0030] The final stirring speed is obtained by taking the weighted sum of the weights of all temperature data points and combining the basic stirring speed setting value and the weight adjustment coefficient.

[0053] In this embodiment, a composite thermal insulation material is provided, wherein the material composition is in the following proportions by weight: cement 700-750, silica fume powder 80-90, black diamond 40-50, rubber powder 35-40, water reducer 0.8-1.2, water increaser 0.8-1.2, cellulose 8-9, aerogel 3-4, particles 40-50, hollow glass microspheres 10-15, silicone waterproofing agent 0.5-1.0, and antioxidant 0.3-0.5.

[0054] The applicant of the present invention has previously proposed a composite thermal insulation material. The composite thermal insulation material has been optimized and the material ratio has been re-adjusted. Hollow glass microspheres, silicone waterproofing agents, and antioxidants have been newly added to improve the performance of the composite thermal insulation material. In the above material ratio of the present invention, the nano-aerogel particles have higher porosity and lower thermal conductivity, and after surface hydrophobic modification, they can better exert their thermal insulation performance, effectively reduce heat transfer, further reduce the thermal conductivity of the material, and have more significant thermal insulation effects; the added hollow glass microspheres or ceramic microspheres The beads are light in weight and have low thermal conductivity, which can form more insulating air layers in the material, further hindering the conduction of heat and improving the overall thermal insulation performance.

The combination of the two optimizes the working performance of the material, has better fluidity and water retention, is easier to operate during construction, is less likely to cause water bleeding and segregation, and improves construction quality and efficiency.

[0076] Regulating indoor humidity: The microporous structure of diatomaceous earth can absorb and release moisture, which can regulate indoor humidity to a certain extent and improve living comfort.

[0077] A method for preparing an energy-saving and environmentally friendly wall comprises the following steps:

[0078] (1) Raw material preparation: The wall material includes the following raw materials in parts by weight: 30 parts of diatomaceous earth; 20 parts of zirconium anhydride ceramic microbeads; 10 parts of PC plastic resin; 5 parts of nano-aluminate; 10 parts of calcined magnesia; 3 parts of polypropylene fiber; 2 parts of cellulose methyl ether; 3 parts of sodium lignin sulfonate; 2 parts of zirconium coupling agent; 10 parts of expanded perlite; 5 parts of aerogel; the diatomaceous earth, nano-aluminate, calcined magnesia, and expanded perlite are pre-dispersed;

[0079] (2) Mixing and stirring; adding the weighed PC plastic resin, cellulose methyl ether, sodium lignin sulfonate and other organic additives into the special production equipment for energy-saving and environmentally friendly walls, adding water and adjusting the temperature of the temperature control area, and adaptively adjusting the stirring speed based on the temperature change of the raw materials during the stirring process, stirring for 5-10 minutes to make it preliminarily mixed; then slowly adding inorganic powder materials such as zirconium anhydride ceramic microbeads, nano-aluminate, calcined magnesia, expanded perlite, aerogel into the special production equipment for energy-saving and environmentally friendly walls, stirring while adding to ensure that the inorganic powder can be evenly dispersed in the organic additives, and based on the raw materials during the stirring process, the mixing speed is adjusted. The stirring speed is adaptively adjusted according to the temperature change of the raw materials, and the stirring time is about 15-20 minutes. Under the continuous stirring state, the pre-dispersed diatomaceous earth suspension or dispersion is slowly added to the special production equipment, and the stirring is continued for 10-15 minutes to fully mix the diatomaceous earth with other materials. Finally, the polypropylene fiber is added to the special production equipment for energy-saving and environmentally friendly walls, and a zirconium coupling agent is added at the same time. The stirring speed is adaptively adjusted according to the temperature change of the raw materials during the stirring process, and the stirring is continued for 10-15 minutes to evenly distribute the polypropylene fiber in the material, and the zirconium coupling agent is used to improve the bonding strength between the components.

[0080] (3) Molding: Place the fully mixed wall material into a mold, and select the appropriate mold shape and size according to actual needs; press the material in the mold under a certain pressure, which is generally controlled between 5-10 MPa. The pressing time is determined according to the thickness and density requirements of the material, usually 5-10 minutes, so that the material is initially formed in the mold; remove the preliminarily formed wall material from the mold and place it in a curing room for curing; the curing conditions are generally a temperature of 20-25°C, a relative humidity of 70%-80%, and a curing time of not less than 7 days to ensure the material's stable performance and strength development;

[0081] (4) Quality inspection: Conduct quality inspection on the prepared wall materials, including appearance inspection, size measurement, density measurement, thermal conductivity test, compressive strength test, etc., to ensure that the performance indicators of the materials meet the design requirements; finally, combine with composite insulation materials to produce the finished product.

[0082] In an adaptive stirring speed system based on temperature measurement and analysis, multiple temperature sensors are installed within the stirring vessel to acquire real-time temperature data at different locations. These temperature data are equivalent to data points in the data. Different temperature zones are set based on factors such as heat transfer and reaction requirements during the stirring process. Each zone corresponds to a different stirring speed adjustment strategy. For example, in areas with large temperature gradients, the stirring speed may need to be increased to promote heat transfer and uniform mixing; while in areas where the temperature is close to the target value and stable, the stirring speed can be appropriately reduced. For each temperature data point, in addition to its own temperature value, factors such as its position in space and its relationship to surrounding temperature points must also be considered. Temperature data points close to heating or cooling sources may have higher weights because they have a greater impact on the overall temperature distribution. The changing trend of the temperature data point, such as the rate of temperature rise or fall, is observed. Temperature points with faster changing rates may better reflect the key information of the current stirring process and should be given higher weights. Factors such as the intensity of the temperature point (i.e., the magnitude of the temperature value), the degree of isolation in the global temperature field, and the temperature change trend are comprehensively considered, and the weight of its prominent feature selection is determined through a certain calculation method.

[0083] From the above analysis, it can be seen that the method for adaptively adjusting the stirring speed is:

[0084] (6) Determine basic parameters; determine the basic stirring speed setting value v0, and determine the weight adjustment coefficient α, where α is a suitable value determined through experiments or experience;

[0085] (7) Setting temperature sensors; multiple temperature sensors are set in the stirring container of the special production equipment to obtain temperature data at different positions in real time. The number and position of the sensors should be reasonably arranged according to the shape, size and characteristics of the stirring container and the stirring process to ensure that the temperature distribution in the stirring system can be fully and accurately reflected. The temperature sensor collects temperature data in real time and transmits the data to the control system for processing. The frequency of collection should be determined according to the degree of dynamic change of the stirring process. For stirring processes with faster changes, the collection frequency can be increased to adjust the stirring speed more timely.

[0086] (8) Calculate the weight of salient feature selection; for each temperature data point, let T max is the highest temperature among all temperature data points, T min is the lowest temperature, then the intensity of the kth point in the jth temperature data point represents the coefficient I jk It can be expressed as The intensity representative coefficient reflects the temperature intensity of the temperature data point, that is, the relative size of the temperature value of the point in the entire temperature range; calculation based on spatial distance:

[0087] in:

[0088] G jk is the spatial distance between the kth point and the ith point in the jth temperature data point, T jk is the temperature value of the kth point in the jth temperature data point, T ji is the temperature value of the i-th point in the j-th temperature data point, and n is the total number of points participating in the calculation around the j-th temperature data point. This expression measures the degree of isolation by calculating the temperature difference between the point and the surrounding points and the inverse of the spatial distance. The greater the temperature difference and the closer the spatial distance, the higher the isolation index; the adjustment calculation based on the temperature change trend is:

[0089]

[0090] in, is the initial global isolation index calculated based on spatial distance, is the temperature change rate of the kth point in the kth temperature data point, is the average temperature change rate of the entire temperature field;

[0091] The intensity is represented by the coefficient I jk Multiplying with the final global isolation index to obtain the salient feature selection weight

[0092] W jk =I jk ×G jk ×G′ jk ;

[0093] (9) Calculation of stirring speed expression: Assume that there are m temperature detection points and each detection point has n data points. Then the expression of stirring speed v can be expressed as:

[0094] The final stirring speed is obtained by taking the weighted sum of the weights of all temperature data points and combining the basic stirring speed setting value and the weight adjustment coefficient.
