Abstract
The invention relates to a nano intensified-nylon-6 composite, which is prepared by blending the following major materials according to different percentages, melting and extruding the materials under the temperature of 215 DEG C to 250 DEG C: 50 percent to 70 percent of nylon slices, 25 percent to 30 percent of glass fiber, 0.05 percent to 0.1 percent of antioxidant I, 0.05 percent to 0.1 percent of antioxidant II, 1 percent to 1.5 percent of lubricant, 0.5 percent to 1 percent of nano material and 0.25 percent to 1 percent of coupling agent; the invention needs no compatilizer and tackifier, greatly reduces the cost, solves the problem that the glass fiber of the engineering plastics is exposed during the injection molding process, improves the appearance quality of the products and enhances the physical indexes of the products to a certain degree, thus changing the situation that some domestic manufacturers depend on the imported nylon. The composite of the invention can be used for the automobile and electromechanical industry fields, can be acted as a thin-walled complicated structural product due to the high rigidness, and is an environment protective product that can substitute the present halogenous fire retardants due to the fire resistance, which is energy conservative and environment protective and is an ideal product for the current engineering plastic modificationindustry.
Description
Technical field: [0001] The invention relates to the field of engineering plastics, in particular to a nanoscale reinforced nylon 6 composition and a preparation method thereof. Background technique [0002] The peripheral parts of automobile engines are mainly heat-generating and vibrating parts, so the materials used must have high comprehensive performance. However, due to the poor dispersion and fluidity of glass fibers, there are obvious weld marks and flow marks on the surface of injection molded products, and there are even glass fibers. The phenomenon of fiber exposure seriously affects the appearance of the product. Nylon has the advantages of high strength, wear resistance, solvent resistance, good self-lubricating property and wide temperature range. It has outstanding chemical resistance and oil resistance. It is the most widely used variety among the five major engineering plastics. It is now widely used in various electronic and electrical equipment. and home ...
