Technical Field

[0001] The present invention relates to the field of polymer material manufacturing, and in particular to a composite additive manufacturing method for polymer materials. Background Art

[0002] With the continuous development and improvement of additive manufacturing technology, composite additive manufacturing technology is also constantly improving. In the future, composite additive manufacturing technology will pay more attention to the optimization of material properties, the reduction of production costs and the improvement of production efficiency; at the same time, with the continuous emergence of new composite materials, the application field of composite additive manufacturing technology will be further expanded.

[0003] Polymer materials are widely used in various fields of national economy and people's life due to their excellent performance and low price. However, in the prior art, many scraps are discarded in large quantities during industrial production. In order to reasonably recycle these scraps and make certain use of them, it is very necessary to design and deploy a method that can control the reaction process by analyzing the polymerization effect.

[0004] Chinese patent application number: CN104860620A discloses a polymer copolymer reinforced lightweight gypsum decorative material, which is prepared by adding the following auxiliary materials in parts by mass to 100 parts by mass of gypsum raw materials: 0.3-30 parts by mass of polymer copolymer reinforcing material, 40-85 parts by mass of water, 0.01-6.5 parts by mass of retarder, 4.0-55 parts by mass of lightweight filling material, 0.3-25 parts by mass of fiber filling material, and 0-35 parts by mass of white cement; the invented material can reduce the bulk density of the polymer reinforced lightweight gypsum decorative material after molding, greatly reducing the load on the building structure; at the same time, due to the formula and process method provided by the invention, each component can be evenly dispersed in the gypsum raw material, ensuring that it has sufficient use strength, basically without increasing the cost, and fundamentally solving the problem that the existing gypsum decorative materials increase the load on the building structure due to their large bulk density.

[0005] However, the above method has the following problems: the actual use environment is not taken into consideration, and the use of traditional methods to plasticize materials will deteriorate the compatibility between materials, thereby affecting performance. Summary of the invention

[0006] To this end, the present invention provides a composite additive manufacturing method for polymer materials, which is used to overcome the problem in the prior art that the compatibility between materials deteriorates, thereby affecting the performance.

[0007] To achieve the above object, the present invention provides a composite additive manufacturing method for polymer materials, comprising:

[0008] Feeding polymer material pellets from a feed hopper into an extruder, and extruding the pellets into a tube core mold of the polymer material through an extrusion die;

[0009] The tube core mold and the pellets are melted into a whole and rounded into a tube core semi-finished product;

[0012] Winding and collecting the finished tube core product, and catalyzing it to generate a corresponding polymer material;

[0013] Placing the polymer material into an organic solvent and testing several polymerization effects of the polymer material;

[0014] According to the test results, the particle size of the pellets, the wall thickness of the tube core mold and the radius of the tube core are adjusted;

[0015] Wherein, the polymerization effect includes the density of the polymer material and the uniformity of the polymer material.

[0016] Furthermore, the step of testing the polymerization effect of the polymer material comprises:

[0017] Measuring the polymer material using a density balance to form a number of measurement results;

[0018] Draw a corresponding polymerization effect image according to the measurement results, and fit the polymerization effect data image that does not reach the corresponding polymerization threshold to form several polymerization characteristics of the polymer material;

[0019] Compare the percentage of polymerization effect data that reaches the polymerization threshold with the standard percentage. If it does not reach the standard percentage, adjust the particle size of the pellets.

[0020] Wherein, the polymerization threshold is the minimum standard of the polymerization effect of the polymer material;

[0021] The aggregation threshold includes a density aggregation threshold and a uniformity aggregation threshold;

[0022] The standard percentage is the minimum proportion of the aggregation effect data that reaches the corresponding aggregation threshold relative to the standard aggregation effect data.

[0023] Furthermore, the pellets of the polymer material enter the extrusion die of the extruder from the feed hopper, and are formed into a semi-finished product with a radius of a target size under the action of the extrusion die.

[0024] Wherein, the radius is the radius of the molded tube core.

[0025] Furthermore, the process of removing the tube die mold from the tube die with mold is as follows:

[0026] The extruder extrude the polymer material, and continuously extrude the polymer material into the tube core mold in a dragging manner;

[0037] The polymer material is separated from the tube core mold to form the tube core finished product.

[0038] Furthermore, the step of determining the proportion of the aggregation effect includes:

[0039] Setting an aggregation threshold, and comparing the aggregation effect data with the aggregation threshold;

[0040] If the aggregation effect data is greater than the aggregation threshold, it is determined that the aggregation standard is met, otherwise the aggregation standard is not met;

[0041] For a single polymer material, the ratio of the number of tests that meet the polymerization standard to the total number of tests is taken as the polymerization effect ratio.

[0042] Furthermore, the step of drawing the aggregate effect image includes:

[0043] Testing the uniformity and density of the polymer material respectively;

[0044] A uniformity image and a density image are drawn, and images that do not reach the corresponding polymerization threshold are fitted, and the fitting results are used as the uniformity polymerization characteristics or density polymerization characteristics of the polymer material.

[0045] Further, adjusting the particle size of the pellets includes setting a standard percentage and comparing the proportion of polymerization effect data reaching a density polymerization threshold;

[0046] If the proportion of the polymerization effect data reaching the polymerization threshold is greater than the standard percentage, it is determined that there is no need to adjust the particle size of the particles, otherwise the particle size of the particles is reduced.

[0047] Furthermore, when the polymer material is generated, the wound and collected tube core finished product is horizontally immersed in a corresponding catalyst.

[0048] Compared with the prior art, the present invention utilizes the method of setting the polymerization threshold value and the standard percentage, melts and cools the polymer material, and reacts the catalyst with the polymer material mixture, thereby achieving a full record of the polymer material polymerization process, making the polymerization efficiency higher, reducing the polymerization error rate, and improving the utilization rate of the polymer material.

[0049] Furthermore, by testing the polymerization effect of polymer materials, the polymerization efficiency can be made higher, the polymerization error rate can be reduced, and the utilization rate of polymer materials can be improved.

[0050] Furthermore, by forming polymer material pellets into polymer material with a radius of a target size under the action of an extrusion die, the polymerization efficiency can be made higher and the utilization rate of the polymer material can be improved.

[0051] Furthermore, by squeezing the polymer material into the tube core mold in a dragging manner, the tube core mold can be more completely removed and the tube core mold can be reused, thereby further improving the utilization rate of the polymer material.

[0052] Furthermore, by performing melt spheronization on the tube core mold, the polymerization efficiency can be made higher, the polymerization error rate can be reduced, and the utilization rate of the polymer material can be improved.

[0053] Furthermore, by further melting and cooling the semi-finished tube core product and strengthening the penetration and wetting bonding of the polymer material, the polymerization efficiency can be made higher, thereby further improving the utilization rate of the polymer material.

[0054] Furthermore, by setting a polymerization threshold, the full recording of the polymer material polymerization process is achieved, which makes the polymerization efficiency higher and effectively reduces the polymerization error rate, thereby further improving the utilization rate of the polymer material.

[0080] Step S13, comparing the percentage of polymerization effect data reaching the polymerization threshold with the standard percentage, and if it does not reach the standard percentage, adjusting the particle size of the particles;

[0081] Among them, the polymerization threshold is the minimum standard for the polymerization effect of polymer materials;

[0082] The aggregation threshold includes a density aggregation threshold and a uniformity aggregation threshold;

[0083] The standard percentage is the minimum proportion of the aggregated effect data that reaches the corresponding aggregation threshold relative to the standard aggregated effect data.

[0084] By testing the polymerization effect of polymer materials, the polymerization efficiency can be made higher, the polymerization error rate can be reduced, and the utilization rate of polymer materials can be improved.

[0085] Specifically, the polymer material pellets enter the extrusion die of the extruder from the feed hopper and are formed into semi-finished products with a radius of the target size under the action of the extrusion die.

[0086] Wherein, radius is the radius of the core with mold.

[0087] By forming polymer material pellets into polymer materials with a radius of a target size under the action of an extrusion die, the polymerization efficiency can be made higher and the utilization rate of the polymer material can be improved.

[0088] Specifically, the process of removing the tube die mold from the tube die with mold is as follows:

[0089] The extruder extrude the polymer material and continuously extrude the polymer material into the tube core mold in a dragging manner;

[0090] If the radius of the polymer material coming out of the tube core mold does not reach the target size, it is determined that the wall thickness of the tube core mold should be reduced.

[0091] By squeezing the polymer material into the tube core mold in a dragging manner, the tube core mold can be more completely removed and the tube core mold can be reused, thereby further improving the utilization rate of the polymer material.

[0092] Specifically, the steps of forming a semi-finished tube core include:

[0093] The steps of forming a semi-finished tube core include:

[0094] rotating the heat press around the die mold;

[0095] Winding a hot pressing heating roller around the tube core mold and melting the pellets and the tube core mold into a whole;

[0096] The hot pressing and heating rollers are rolled to round the whole body to form a semi-finished tube core;

[0097] Among them, the hot pressing heating roller is composed of a plurality of heated circular rollers and can rotate around the tube core semi-finished product.

[0098] See also Figure 3 and Figure 4 As shown, they are respectively a schematic diagram of forming a semi-finished tube core according to an embodiment of the present invention and a schematic diagram of demoulding a polymer material according to an embodiment of the present invention. In implementation, polymer material pellets enter the extrusion die of the extruder from the feed hopper, and under the action of the extrusion die, a polymer material body with a radius fixed to the size 1 of the polymer material tube core is formed.

[0099] The extruder extrude the polymer material body, and the polymer material body is continuously squeezed into the polymer material tube core 2 in a dragging manner.

[0100] The hot press rotates around the polymer material tube core 2, and the hot press heating roller is wound on the polymer material tube core 2. The hot press heating roller melts the polymer film 21 wound on the polymer material tube core 2, and performs a rounding process on the melted polymer material tube core 22.

[0101] Understandably, Figure 3 This is only a special rounding method. In practice, it can also be rounded into a cylinder or a sphere, which will not be described in detail here.

[0102] By performing melt spheronization on the tube core mold, the polymerization efficiency can be made higher, the polymerization error rate can be reduced, and the utilization rate of the polymer material can be improved.

[0103] Specifically, the steps of forming the finished tube core include:

[0104] The semi-finished tube core is melted and placed in a heater for deep melting;

[0105] Enter the cooler to cool and shape, forming a semi-detached tube core semi-finished product;

[0106] Push or pull the corresponding part of the semi-finished tube core;

[0107] The polymer material is released from the tube die to form a finished tube die.

[0108] By further melting and cooling the semi-finished tube core product and strengthening the penetration and wetting bonding of the polymer material, the polymerization efficiency can be made higher, thereby further improving the utilization rate of the polymer material.

[0109] Specifically, the steps to determine the proportion of aggregation effect include:

[0110] Set an aggregation threshold and compare the aggregation effect data with the aggregation threshold;

[0111] If the aggregation effect data is greater than the aggregation threshold, it is judged that the aggregation standard is met, otherwise it does not meet the aggregation standard;

[0112] For a single polymer material, the ratio of the number of tests that meet the polymerization standard to the total number of tests is taken as the polymerization effect ratio.

[0113] By setting a polymerization threshold, the entire polymerization process of polymer materials can be recorded, making the polymerization efficiency higher and effectively reducing the polymerization error rate, thereby further improving the utilization rate of polymer materials.

[0114] Specifically, the steps of drawing the aggregation effect image include:

[0115] Polymer materials are tested for uniformity and density respectively;

[0116] A uniformity image and a density image are drawn, and images that do not reach the corresponding polymerization threshold are fitted, and the fitting results are used as uniformity polymerization characteristics or density polymerization characteristics of the polymer material.

[0117] By drawing the polymerization effect image and fitting the polymerization effect data image that has not reached the polymerization threshold, the polymerization characteristics of the polymer material are determined, and the full record of the polymer material polymerization process is achieved, making the polymerization efficiency higher, thereby further improving the utilization rate of the polymer material.

[0120] Embodiment 2:

[0121] Place the finished polymer material in a 90% alcohol solution, with a density polymerization threshold of 10g / cm 3 , using a density balance to measure several polymer material products, the first measurement result was 7g / cm 3 The second measurement result is 8g / cm 3 The third measurement result is 9g / cm 3 The fourth measurement result is 12g / cm 3 The fifth measurement result is 13g / cm 3 , the proportion of aggregation effect data that reaches the density aggregation threshold is 40%.

[0122] Specifically, the adjustment of the particle size of the pellets includes setting a standard percentage and comparing the proportion of the aggregation effect data that reaches the density aggregation threshold;

[0123] Among them, if the proportion of polymerization effect data reaching the polymerization threshold is greater than the standard percentage, it is judged that there is no need to adjust the particle size of the particles, otherwise the particle size of the particles is reduced.

[0124] It can be understood that the uniformity is the density of each part of the polymer material, and during the test, the test can be performed according to the above method.

[0125] Embodiment 3:

[0126] For finished polymer materials, the polymerization effect data that reaches the polymerization threshold accounts for 55%, the particle size is 0.9 mm, and the standard percentage is 45%. It is judged that the standard percentage is reached and there is no need to adjust the particle size of the particles.

[0127] Embodiment 4:

[0128] For finished polymer materials, the polymerization effect data that reaches the polymerization threshold accounts for 55%, the particle size is 0.9 mm, and the standard percentage is 60%. It is judged that the standard percentage is not reached, and the particle size of the particles is reduced.

[0129] Embodiment 5:

[0130] For two polymer material finished products A and B produced at the same time, the polymerization effect data of finished product A that reaches the polymerization threshold accounts for 65%, and the particle size is 0.9mm. The polymerization effect data of finished product B that reaches the polymerization threshold accounts for 55%, and the particle size is 0.9mm. The standard percentage is 60%. If finished product A reaches the standard percentage and finished product B does not reach the standard percentage, it is judged that the particle sizes of polymer materials A and B need to be reduced at the same time.

[0131] In particular, for target polymer materials generated simultaneously, the difference in their corresponding standard percentages should not exceed 10%.

[0132] Specifically, when the polymer material is produced, the finished tube core product collected by winding is horizontally immersed in the corresponding catalyst.

[0133] By horizontally immersing the wound and collected tube core products into corresponding catalysts to generate polymer materials, the polymerization efficiency can be made higher, thereby further improving the utilization rate of the polymer materials.

[0134] By adjusting the particle size of the particles, the polymerization efficiency can be made higher, thereby further improving the utilization rate of the polymer material.
