Description

Technical Field

[0001] The invention relates to the technical field of non-foaming PU material and fiber cloth molding technology, and in particular to a non-foaming PU material and fiber cloth integral molding technology. Background Art

[0002] In the related art, the existing non-foamed PU materials have excellent performance and are widely used in the production of daily necessities, such as shoes or protective gear. At present, non-foamed PU materials are often single in color and transparent or translucent. Therefore, in order to improve the aesthetics, grid printing is often used to print patterns on the outer surface of the non-foamed PU material; however, such a molding process has the following disadvantages: First, the pattern is printed on the outer surface of the non-foamed PU material by grid printing. The outer surface of the non-foamed PU material must be cleaned with chemical agents such as cleaning agents and treatment agents before printing. Chemical agents such as cleaning agents and treatment agents are not environmentally friendly during use, which can easily cause environmental pollution during the preparation process and harm the health of users; second, the fiber cloth is exposed to the outside of the non-foamed PU material. Long-term use can easily cause the pattern and pattern on the fiber cloth to fade and discolor, and it is easy to be damaged by external friction.

[0003] With regard to the related art, a grid printing method is used to print a pattern on the outer surface of a non-foamed PU material. The outer surface of the non-foamed PU material must be cleaned with chemical agents such as cleaning agents and treatment agents before printing can be performed. Chemical agents such as cleaning agents and treatment agents are not environmentally friendly during use, and are likely to cause environmental pollution during the preparation process, while harming the health of the user. In addition, the fiber cloth is exposed to the outside of the non-foamed PU material. Long-term use can easily cause the pattern and design on the fiber cloth to fade and discolor, and it is easily damaged by external friction. There is still a lack of a better technical solution. Summary of the invention

[0004] In view of this, it is necessary to provide an integrated molding process of non-foamed PU material and fiber cloth, so as to at least solve the problem that the grid printing method is used in the related art to print the pattern on the outer surface of the non-foamed PU material. The outer surface of the non-foamed PU material must be cleaned with chemical agents such as cleaning agents and treatment agents before printing. Chemical agents such as cleaning agents and treatment agents are not environmentally friendly during use, which can easily cause environmental pollution during the preparation process and harm the health of the user. The fiber cloth is exposed to the outside of the non-foamed PU material. Long-term use can easily cause the pattern and design on the fiber cloth to fade and discolor, and it is easily damaged by external friction.

[0005] The embodiment of the present application provides a process for integrally forming a non-foamed PU material and a fiber cloth, which comprises the following steps:

[0006] S1, preparing a non-foaming polyurethane raw material, preparing a liquid non-foaming polyurethane glue A and a liquid non-foaming polyurethane glue B, pouring them into a stirring device, and the stirring device fully and evenly stirs the liquid non-foaming polyurethane glue A and the liquid non-foaming polyurethane glue B according to a preset weight ratio to obtain the liquid non-foaming polyurethane raw material; wherein the liquid non-foaming polyurethane raw material is transparent or translucent;

[0007] S2, preparing fiber cloth and a molding mold; wherein the surface of the fiber cloth can be printed with patterns of different patterns and colors according to requirements;

[0008] S3, placing the fiber cloth in the molding mold, and then pouring the liquid non-foaming polyurethane raw material into the molding mold to obtain a solid finished product; wherein the liquid non-foaming polyurethane raw material permeates the fiber cloth, so that the solid non-foaming polyurethane raw material is molded on the outside of the fiber cloth.

[0009] In one embodiment, in step S3, the liquid non-foaming polyurethane raw material can also be poured into the molding mold, and then the fiber cloth is placed in the molding mold to obtain a liquid finished product.

[0010] The beneficial effects of the present invention are as follows: the present application has a reasonable design, and a transparent finished product or a translucent finished product is obtained by adopting a process of integrally forming a non-foamed PU material and a fiber cloth, and the fiber cloth is embedded in the non-foamed PU material, which has an atmospheric and beautiful appearance. The non-foamed PU material has excellent hardness and wear resistance, and can effectively protect the patterns on the fiber cloth from external damage, and is not easy to fade or discolor. The patterns on the fiber cloth can be preserved for a long time and remain as new after long-term use. At the same time, embedding the fiber cloth in the non-foamed PU material replaces the traditional process of printing patterns on the outer surface of the non-foamed PU material by grid printing, and there is no need to use chemical agents such as cleaning agents and treatment agents, thereby avoiding the problem that the chemical agents are unfriendly to the environment during use, which easily causes pollution to the environment during the preparation process and damages the health of the user, and the practicability is strong.
