AI Technical Summary

Problems solved by technology

[0004] 1. The organic filler is easy to agglomerate during the addition process, and it is not easy to open the agglomeration by stirring in the substrate, so the addition is uneven
[0005] 2. Due to the difference in density between the organic filler and the substrate, the filler tends to float or sink during the addition process, resulting in uneven dispersion, which makes the material modification fail to achieve the expected effect. This problem is especially obvious in substrates with low viscosity

Embodiment 1

[0035] 1. Embryo making: The mold is a compression mold, and the tetrafluoroethylene powder is placed in the lower mold cavity. The shape of the cavity can be a cuboid, cylinder or other shapes. The cavity design should fully consider the uniform heating of the powder and Easy demoulding (especially for complex cavity shapes);

[0036] 2. The upper part of the mold can press the powder, and at this time, apply 10MPa to the powder;

[0037] 3. Heat the mold. A better process can make the powder evenly heated. The temperature is 400°C and the time is 500 minutes;

Abstract

The invention provides a resin base composite material. The resin base composite material is prepared through the following steps of placing resin powder into a cold stamping die which can be heated,and performing cold stamping, heating and sintering and cooling, so as to obtain a sintered blank material; heating and melting a thermoset resin to form thermoset resin molten fluid; and soaking thesintered blank material in the thermoset resin molten fluid, performing standing, taking the sintered blank material after standing out, and performing cooling, so as to obtain the resin base composite material. According to the resin base composite material prepared by the invention, after cold stamping and sintering, the blank is obtained, the multi-hole sintered blank material is used as a filler to be macerated in a thermoset resin molten fluid base material, the thermoset resin molten fluid sufficiently macerates and stuffs gaps of the sintered blank material, after cooling, the sinteredblank material is taken out, the thermoset resin is solidified to form a novel resin composite material, the sintered blank material in the material can be easily and uniformly mixed with the base materials, and the resin composite material is directly fine processed on a machine tool to be prepared into spare parts in appropriate shapes, so that the wear resistance, corrosion resistance and shockresistance of finished products are improved, and the service life can be greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a method for preparing polar polymer splits by low-temperature plasma. Background technique [0002] Cast polyurethane, epoxy resin, cast nylon and other thermosetting materials have been widely used in composite materials, such as tires, due to their excellent mechanical properties, wear resistance, compression resistance, tear resistance, solvent resistance, and aging resistance. , rubber rollers, conveyor belts, anti-corrosion coatings, sealing rings, wear-resistant parts and other industrial fields and people's livelihood fields. However, although these engineering materials have excellent performance, with the development of processing technology and the requirements of the use environment, in more and more environments, materials are required to have more excellent performance, such as high impact resistance, high strength and high Tear r...
