Nylon composite material excellent in waterproofing and wear-resisting properties and preparation method of composite material

Abstract

The invention discloses a nylon composite material excellent in waterproofing and wear-resisting properties. The composite material is characterized by being prepared from the following raw materials in parts by weight: 0.1-0.3 part of diphenylamine, 5-7 parts of precipitated barium sulfate, 8-12 parts of graphite fiber, 0.5-1 part of polyethylene wax, 2-4 parts of nano aluminum nitride, 1-2 parts of sodium lignin sulfonate, 90-100 parts of nylon 6, 2.5-3.2 parts of lithium chloride, 3-9 parts of epoxy resin E51, 10-15 parts of an EVA emulsion, 60-80 parts of ethyl acetate, 1-3 parts of castor oil, 4-7 parts of ethylene / vinyl alcohol copolymer powder and 15-30 parts of distilled water. By adding the graphite fiber, the wear resistance, the toughness, the rigidity and other properties of the material are enhanced; the added precipitated barium sulfate has the advantages of strong chemical inertness, good stability, acid and base resistance, and moderate hardness, and is able to absorb harmful rays an the like; by adding the nano aluminum nitride, the mechanical performance and heat-conducting effect of a finished product are significantly improved; and the material disclosed by the invention is excellent in waterproofing and heat-conducting effects, simple in processing and worthy of popularizing.

Description

technical field [0001] The invention relates to a nylon composite material with good waterproof and wear-resistant properties and a preparation method thereof, belonging to the technical field of nylon production. Background technique [0002] With the rapid development of modern society, the pressure of work and study is gradually increasing, and more and more young people are more and more passionate about outdoor sports. Outdoor sports can not only make people feel the magic of nature away from the hustle and bustle of the city, but also bring people more challenges and stimulations, broaden their horizons and regulate stress. Currently the most popular outdoor sports include hiking, mountain climbing, cycling, river tracing, camping and so on. It is particularly important to choose clothes with good waterproof and wear resistance for outdoor sports.

Problems solved by technology

[0003] Nylon 6 is a widely used engineering plastic with excellent comprehensive performance, but it has the disadvantages of poor resistance to strong acid and strong alkali, low dry and low temperature impact strength, high water absorption, etc., and the processing temperature of nylon 6 is relatively high. Increased production costs, high requirements for production equipment, not conducive to large-scale production

The low-melting-point nylon 6 currently on the market is mainly prepared by foreign companies through synthetic methods. This method has disadvantages such as complex processing technology and high cost. However, domestic research on low-melting point is still in the laboratory stage and is difficult to achieve. Industrialized large-scale production, so it is the focus of current research to obtain nylon 6 with a low melting point through modification. It has many excellent properties, but it also has disadvantages such as poor impact strength and poor heat resistance. Therefore, on the basis of low melting point nylon 6 matrix In addition, it is necessary to modify low-melting point nylon 6 by filling, strengthening, copolymerization, blending and other methods to increase the versatility of application
