Abstract

The invention discloses a high-elasticity vibration-resistant expanded polyethylene plate and a method for manufacturing the same. The high-elasticity vibration-resistant expanded polyethylene plate comprises, by weight, 120-140 parts of polyethylene, 20-30 parts of ethylene-vinyl acetate copolymers, 10-14 parts of p-toluenesulfonhydrazide, 5-8 parts of dichlorotetrafluoroethane, 3-5 parts of dicumyl peroxide, 7-9 parts of zinc oxide, 40-50 parts of titanate-modified calcium carbonate, 8-10 parts of leucite powder, 5-7 parts of dynasylan ibteo, 6-9 parts of magnesium stearate, 4-6 parts of butyl stearate, 4-5 parts of hexamethylenetetramine, 3-5 parts of polycarbonate, 10-14 parts of aluminum hydroxide, 7-9 parts of titanium nitride whiskers, 6-8 parts of dioctyl adipate, 3-5 parts of 2-aminoethanol, 8-9 parts of dicyclohexyl phthalate, 7-9 parts of magnesium diboride and 4-6 parts of jade powder. The high-elasticity vibration-resistant expanded polyethylene plate and the method have the advantages that the polyethylene plate manufactured by the aid of the method not only is excellent in vibration-resistant and buffer performance, but also is high in mechanical strength and good in ageing resistant, and good flame-retardant effects can be realized.

Description

technical field [0001] The invention relates to a polyethylene sheet, in particular to a high-elasticity shock-resistant foamed polyethylene sheet and a preparation method thereof. Background technique [0002] Foamed polyethylene, commonly known as pearl cotton, is a new type of environmentally friendly packaging material with high-strength cushioning, shock-absorbing and shock-resistant capabilities. It is flexible, light, elastic, and has good resilience. It can absorb and disperse external impact by bending to achieve a cushioning effect. At the same time, foamed polyethylene has a series of superior performance characteristics such as heat preservation, moisture resistance, friction resistance and corrosion resistance. At present, it is widely used in the packaging of IT, electronics, electrical appliances, hardware and electromechanical, advanced audio-visual, precision instruments, high-end furniture, life jackets and other products. However, polyethylene foam mate...
