Problems solved by technology

The advantage of this technology is that it is simple to implement, but the disadvantage is that the cost of laser marking agents is often very expensive, and the inappropriate addition ratio will affect the mechanical properties of the material. At the same time, many laser marking agents contain heavy metal components, which not only pollute the environment, but also easily produce color pollution. , is not conducive to the realization of color matching

Abstract

The invention discloses a nylon / polyphenylene sulfide alloy material and a preparation method thereof. The nylon / polyphenylene sulfide alloy material comprises following components in parts by weight:35 to 80 parts of nylon, 1 to 10 parts of polyphenylene sulfide, and 20 to 50 parts of glass fibers. By adding a certain amount of polyphenylene sulfide resin into nylon resin, and then the mixture is reinforced by glass fibers to prepare the nylon / polyphenylene sulfide alloy material. Compared with a common laser labeling agent modified enhanced nylon material, the provided nylon / polyphenylene sulfide alloy material has a good mechanical property and an excellent laser labeling performance, does not contain any heavy metal, is environmentally friendly and pollution free, and is beneficial for color matching. The alloy material is resistant to fading in a high temperature high humidity environment, and also has a good laser labeling effect, and moreover, the application range is enlarged.

Description

technical field [0001] The invention belongs to the technical field of nylon modification, and in particular relates to a nylon / polyphenylene sulfide alloy material and a preparation method thereof. Background technique [0002] Polyamide resin has excellent comprehensive properties such as excellent mechanical properties, excellent barrier properties, heat resistance, wear resistance, and chemical corrosion resistance, and is widely used in the fields of machinery manufacturing, electric tools, electronic appliances, and transportation. Especially in the electronic and electrical industry, many parts are marked by laser marking, which requires nylon materials to have good laser marking performance. Nylon materials are generally difficult to mark. To obtain a better laser marking effect, laser marking agents must be added. [0003] Patent CN201810350929 discloses a modified nylon that can be laser marked. By adding a laser marking agent, the nylon has a good laser marking e...
