Manufacturing method for polymer composite products

Abstract

The invention discloses a manufacturing method for polymer composite products. The method comprises a preparation step, a pre-treatment step, a combination step and a cooling step. The preparation step is to form a semi-finished product by using a non-polymer material and form a to-be-treated member capable of cooperating with the semi-finished product by using the polymer material; the pre-treatment step is to heat the to-be-treated member and to coat an adhesion agent on the semi-finished product; the combination step is to combines the semi-finished product and the to-be-treated member; and the cooling step is to cool the to-be-treated member. In the pre-treatment step, the semi-finished product and the to-be-treated member are formed in advance, so that size precision and possible deformation of the semi-finished product and the to-be-treated member can be controlled accurately so as to increase shape accuracy; and in cooperation with the adhesion agent and the characteristic of expansion caused by heat and contraction caused by cold of the material, so that the combination force between the semi-finished product and the to-be-treated member can be greatly increased.

Description

technical field [0001] The invention relates to a manufacturing method of a composite material product, in particular to a manufacturing method of a polymer composite product. Background technique [0002] With the improvement of industrial technology and living standards, people have higher and higher requirements for various products, not only require cheap price and practicality, but also further require beautiful appearance, light weight, and long service life...etc. [0003] Therefore, in recent years, there are more and more composite material products. Combining the material properties of different materials to meet people's diverse needs, plastic injection-coated composite material products are the most common. [0004] refer to figure 1 , the practice of the existing plastic injection package composite material product 11 (injection package molding) is to place the formed product 12 in an injection mold 100 in advance, then heat the plastic 13 into a liquid state a...

Problems solved by technology

[0006] 1. Severe deformation: As we all know, the molding shrinkage rate of each plastic material is different. Therefore, the product 12 covered by the injected plastic 13 will bear the pressure generated when the plastic material shrinks.

However, as various products become lighter and thinner, the product 12 covered by the injected plastic 13 is also getting thinner and thinner. Therefore, the product 12 cannot effectively resist the shrinkage of the plastic material. The pressure generated is prone to serious warping deformation

[0007] 2. Poor binding force: In addition, the original binding force between heterogeneous materials is not good, and the contact area between the product 12 and the plastic 13 is greatly reduced due to the thinning, resulting in a weaker binding force between the product 12 and the plastic 13 Weak and prone to peeling
