Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a method for preventing hollowing of a thermal insulation nano-gel material used on concrete surfaces. Background Technology

[0002] Existing technology (1): Manual slurry application and roughening. The main construction process is as follows: base treatment → preparation of polymer cement mortar for later use → slurry application and roughening → roughening curing → making insulation layer mortar spots → application of insulation material to the wall → crack-resistant mortar (embedded with fiberglass mesh). The main operation method is as follows: use a slurry made of steel wire mesh that has been folded multiple times, then dip the back of the slurry into an appropriate amount of slurry, and manually slap and pull it to form a rough surface with a rough bottom and a pointed top, so that the base treatment is uniform and firm. Then start curing the day after slurry application. When the weather is dry, it is advisable to cure 5 hours after slurry application. Curing should last no less than 3 days. The curing effect should be such that the mortar cannot be bent by hand and there is a rough feeling when you press your hand on the mortar before the insulation material can be applied to the wall.

[0003] However, the existing technology has the following shortcomings: after the sizing and brushing, it is necessary to arrange for a dedicated person to maintain it regularly, which will increase labor costs; at the same time, if the maintenance of certain parts is not in place or too much water is sprayed during maintenance, it may lead to insufficient burr strength and cause the burrs to fall off, ultimately resulting in hollowing later.

[0004] Existing technology two: applying an interface agent to the substrate, i.e., manually applying the interface treatment agent with a roller to the aluminum formwork concrete substrate. After on-site testing, this construction technology was found to easily result in large-area hollow areas in the insulation layer, and rectification would increase labor and material costs. Summary of the Invention

[0005] In view of this, the present invention provides a method for preventing hollowing of thermal insulation nano gel material used on concrete surfaces, which reduces subsequent repairs, improves project quality, reduces material consumption, lowers project costs, and speeds up construction progress.

[0023] Explanation of the markings in the attached diagram: 1. Base layer; 2. Two-component vitrified tile backing adhesive; 3. Thermal insulation layer; 4. Crack-resistant layer; 5. Putty layer; 6. Finishing layer. Detailed Implementation

[0024] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0026] This invention discloses a method for preventing hollowing of a thermal insulation nano-gel material used on concrete surfaces.

[0027] Reference Figure 1 A method for preventing hollowing of a thermal insulation nano-gel material used on concrete surfaces includes the following construction steps:

[0028] S1: Base layer 1 treatment;

[0029] S2: Spraying two-component vitrified tile backing adhesive 2;

[0030] S3: Create an insulation layer 3 by applying insulation ribs to the wall surface;

[0031] S4: Insulation layer construction;

[0032] S5: Apply putty layer 5 and then apply finishing layer 6.

[0033] Using a two-component spray-applied vitrified tile backing adhesive 2 results in a low hollow rate, requires no special treatment, saves on material and labor costs, eliminates safety hazards caused by repairs, and speeds up the construction process.

[0034] In S1, the processing method for base layer 1 is as follows:

[0035] The surface was not roughened or roughened during the on-site treatment. After the surface was washed with water, the two-component vitrified tile was sprayed on.

[0036] In S2, the vitrified tile backing adhesive powder and vitrified tile liquid are mixed evenly in a certain proportion, and then the two-component vitrified tile backing adhesive 2 after being finely sieved through a drain basin is loaded into the spraying equipment for spraying.

[0037] The spraying equipment is an oil-free air compressor, which has a feed pipe and a nozzle. The two-component vitrified tile backing adhesive 2 is sprayed out through the feed pipe and the nozzle.

[0038] Specifically, the two-component spray-applied vitrified tile adhesive 2 is designed to improve the bonding strength between adhesive materials and solve common problems such as hollowness and detachment. It consists of vitrified tile adhesive powder and vitrified tile liquid, which are mixed in a specific ratio before use. It features high water resistance, deformation resistance, long-lasting anti-detachment, and impact resistance, effectively preventing hollowness.

[0039] In this embodiment, the on-site application is carried out by spraying. The vitrified tile adhesive powder and vitrified tile liquid are mixed in a ratio of 1:2.5 (by weight). After thorough mixing, the mixture is left to stand for 3 minutes, then mixed again before use. The mixed adhesive should be used within 2 hours.

[0040] Two-component vitrified tile backing adhesive 2 has the following advantages:

[0041] Strong adhesion: It can effectively bond to smooth, low-absorption substrates, preventing hollowing and detachment.

[0042] Weather and Durability: High water resistance, weather resistance, and heat resistance; excellent durability; suitable for various indoor and outdoor environments.

[0043] Anti-seepage and crack prevention: Compatible with cement mortar, it has excellent anti-seepage properties and can effectively resist the formation of cracks.

[0044] Green and environmentally friendly: non-toxic and harmless, meets environmental protection requirements, and is safer to use.

[0045] Easy to install: No need to wait for drying, simplifying the construction process and improving efficiency.

[0046] In section S3, insulation screeding is a crucial step in the construction of external wall insulation projects. Its purpose is to ensure the thickness and flatness of insulation layer 3, thereby improving construction quality. The specific steps and key points of insulation screeding are as follows:

[0047] Preparation for screeding: Before construction, clean and position the surface and lay out the lines. Determine the thickness according to the requirements of the construction design and mark the horizontal and vertical standard lines using an infrared level.

[0048] Making the screed strip: When making the screed strip, use the most convex point of the wall as a reference to make the finished surface of the screed strip.

[0049] Finding the square of inside and outside corners: When finding the square of inside and outside corners for plastering, you should first make a baseline at the inside and outside corners. Use a square to find the square of the outside corner first, and then mark the plastering guideline at the corner of the wall and the ceiling. Make mortar spots and screeds at the top and bottom of the guideline.

[0050] Through this series of steps, the insulation reinforcement can effectively ensure the construction quality and effect of insulation layer 3.

[0051] In S4, after the insulation layer is completed, the crack-resistant layer 4 is applied to the wall. Crack-resistant layer 4 consists of applying crack-resistant mortar.

[0052] The construction method for applying crack-resistant mortar mainly includes the following steps:

[0053] Preliminary preparations:

[0054] Materials needed: crack-resistant mortar, clean water, mixing tools, construction tools, etc.

[0055] Base layer 1 treatment: Ensure that base layer 1 is clean, flat, free of oil stains and dust, and repair cracks or holes.

[0056] Mixing crack-resistant mortar:

[0057] Mix the crack-resistant mortar powder and water according to the specified proportions.

[0058] Mix thoroughly: Use an electric mixer to ensure there are no lumps or dry powder, forming a uniform slurry.

[0059] Construction of crack-resistant mortar:

[0060] Apply the base coat mortar: Apply evenly to the surface of the two-component vitrified tile backing adhesive 2, with a thickness of 1-2 mm.

[0061] Laying anti-crack mesh: Before the bottom mortar is dry, lay anti-crack mesh made of fiberglass mesh and compact it.

[0062] Apply the surface mortar: Apply a second layer of mortar evenly to the crack-resistant mesh, with a thickness of 2-3 mm.

[0063] Crack-resistant mortar maintenance:

[0064] Moisturizing and maintenance: Cover the mortar surface to keep it moist and prevent it from drying out too quickly.

[0065] Prevent vibration: Avoid vibration or impact on the construction site.

[0066] The insulation layer is a heat-insulating nano-gel, applied by coating. This heat-insulating nano-gel offers excellent heat insulation properties, with the following advantages:

[0067] Superior thermal insulation performance: Nano-aerogel insulation material has super thermal insulation performance with nanopores. At normal temperature and pressure, its total thermal conductivity of powder and total thermal conductivity of bulk are extremely low, making it one of the materials with the lowest thermal conductivity in the world in the field of high-temperature thermal insulation.

[0068] Unique flame-through resistance: This gel material can maintain its insulation properties at high temperatures, which is significantly better than other lightweight insulation materials.

[0069] Environmentally friendly and non-toxic: The product is made of environmentally friendly materials, is non-toxic and harmless, meets national environmental protection standards, and is harmless to the human body.

[0070] Easy to apply: The thermal insulation nano gel is easy to apply and requires no special tools. It can be applied directly, saving time and costs.

[0071] In S5, putty layer 5 is applied and finishing layer 6 is applied, which is latex paint.

[0072] The present invention addresses the common problem of hollow areas that easily occur after the interior insulation material is applied to the exterior wall, for which there is no more economical and practical solution. After testing various base layer treatment methods on-site, it was found that after applying vitrified tile backing adhesive, the base layer became rougher and stronger, and no hollow areas were found after the thermal insulation gel was applied.

[0073] Preparation and application of vitrified tile adhesive. The vitrified tile adhesive powder and liquid vitrified tile are mixed evenly in a certain proportion, then passed through a fine sieve in a draining basin. The sieved two-component vitrified tile adhesive 2 is then loaded into an air compressor tank. An oil-free air compressor is used to evenly spray the two-component vitrified tile adhesive 2 onto the base layer 1.

[0074] Once the adhesive strength of the vitrified tile backing meets the standard requirements, insulation screeds can be applied to the wall. Once the screed strength meets the standard requirements, the new type of insulation nano-insulation gel can be applied to the wall.

[0075] This invention eliminates the need for water spraying and curing on each layer, replacing manual slurry application with an efficient device. This solves the burr quality problem, speeds up construction, and saves on material and labor costs.

[0076] This invention has good application effects and broad prospects. Compared with existing technologies, it has less overall material loss, lower labor costs, lower hollow rate, and higher construction efficiency; it also reduces later repairs, improves project quality, reduces material consumption, lowers project costs, and accelerates construction progress.

[0077] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. The above are only preferred embodiments of the present invention. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other occasions without modification, should all be considered within the scope of protection of the present invention.
