Abstract
The invention relates to an ethylene-vinyl acetate copolymer-containing flame retardant heat resistant plastic. The plastic is prepared from the following ingredients in parts by weight: 70-80 parts of ethylene-vinyl acetate copolymer, 30-40 parts of ethyl acrylate, 30-40 parts of vinylacetamide, 10-20 parts of magnesium hydroxide, 10-20 parts of glycerinum, 10-20 parts of limestone and 10-20 parts of polyurethane. The prepared ethylene-vinyl acetate copolymer-containing flame retardant heat resistant plastic has excellent flame retardant and heat resistant effects.
Description
Technical field
The present invention relates to a kind of flame-proof heat-resistant plastics, particularly relate to a kind of flame-proof heat-resistant plastics that contain ethylene-vinyl acetate copolymer.
Background technology
At present, plastics kind is multifarious on the plastics market, and function is different.At different demands.Along with rapid economy development, the client also is more and more higher to the index request of plastic cement.In the professional domain that relates to the flame-resistant high-temperature-resistant plastics, requirement to the flame-proof heat-resistant plastic is to uprise day by day, the plastics kind that has at present good flame-retardance and good high-temperature resistant result on the market simultaneously is considerably less, therefore develops a kind ofly to have excellent flame-retardant performance simultaneously and stable on heating plastics are very urgent.
Summary of the invention
The technical problem that solves: the fire-retardant and relatively poor problem of heat-resisting effect of conventional plastics.
Technical scheme: the present invention is a kind of flame-proof heat-resistant plastics that contain ethylene-vinyl acetate copolymer, is made up of according to weight ratio following composition: 70～80 parts of ethylene-vinyl acetate copolymers, 30～40 parts of ethyl propenoates, 30～40 parts of ethernamines, 10～20 parts of magnesium hydroxides, 10～20 parts of glycerine, 10～20 parts in Wingdale, 10～20 parts of urethane.Under 60 ℃, various compositions are dropped into the reaction vessel allotment, stir, be heated to 200 ℃ and keep 10h, the plastics that can obtain to have good flame-proof heat-resistant effect after the cooling.
Beneficial effect: after preparing the flame-proof heat-resistant plastics that contain ethylene-vinyl acetate copolymer, its flame retardant resistance and high thermal resistance are tested.Adopt the flame retardant of plastic of GB/T 14833-93 to test, the result shows that the flame-proof heat-resistant plastics that contain ethylene-vinyl acetate copolymer that the present invention makes have good flame-retardant effect.Plastics are 800～900 ℃ of maintenance 15h down in scorching hot temperature in addition, and the flame-proof heat-resistant plastics that contain ethylene-vinyl acetate copolymer produce without any unusual phenomenon, have good heat-resisting property.
