Abstract
The invention discloses modified ethylene vinyl-acetate copolymer (EVA) resin plastic. The EVA resin plastic is prepared from EVA resin, i.e., an ethylene vinyl-acetate copolymer, and additives, wherein the additives include a chemical resistant agent, an oil resistant agent, a filling reinforcing agent, a fire retardant and a coupling agent, wherein the chemical resistant agent is chloroprene rubber; the oil resistant agent is acrylonitrile butadiene rubber; the filling reinforcing agent is diatomite; the fire retardant is dicarboxylic ethyl methyl phosphate; the coupling agent is mercapto propyl trimethoxy silane. The modified EVA resin plastic disclosed by the invention, through adding of various additives in the EVA resin, has the characteristics of good chemical resistance, good oil resistance, high strength, high impact toughness, good fire resistance and good product quality.
Description
Technical field
The present invention relates to plastics, particularly relate to a kind of modified EVA resin and plastic.
Background technology
EVA resin, chemical name is ethylene-vinyl acetate copolymer, the content of the vinyl acetate between to for plastic in EVA resin lower than 20% time, at this moment just can be used as plastics and uses.EVA resin has excellent water tolerance, processibility, shock resistance, heat retaining property and sound-proofing, is widely used in the fields such as foaming shoe material, functional canopy film, packing film, hot melt adhesive, electric wire and toy.But along with the progress of social productive forces, existing EVA resin cannot meet industrial user demand gradually, especially, at aspects such as chemical proofing, oil-proofness, intensity, toughness, is greatly restricting the development of EVA resin.In addition, EVA resin itself has high inflammableness, easily blasts, more dangerous during use.
Summary of the invention
The technical problem that the present invention mainly solves is to provide that a kind of chemical proofing is good, oil-proofness is good, intensity is high, toughness is large, the modified EVA resin and plastic of good flame resistance, good product quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of modified EVA resin and plastic is provided, by EVA resin, be that ethylene-vinyl acetate copolymer and additive are made, described additive comprises chemical-resistant resistance agent, oil-proof composition, packing strengthening agent, fire retardant and coupling agent, described chemical-resistant resistance agent is chloroprene rubber, described oil-proof composition is paracril, described packing strengthening agent is diatomite, described fire retardant is dicarboxylic acid ethyl-methyl phosphoric acid ester, described coupling agent is mercaptopropyl trimethoxysilane, the shared weight percent of the each composition of described modified EVA resin and plastic is respectively ethylene-vinyl acetate copolymer and accounts for 84.1%-88.5%, chloroprene rubber accounts for 0.8%-1.7%, paracril accounts for 0.4%-1.3%, diatomite accounts for 7.6%-8.4%, dicarboxylic acid ethyl-methyl phosphoric acid ester accounts for 1.5%-2.4%, mercaptopropyl trimethoxysilane accounts for 1.2%-2.1%.
In a preferred embodiment of the present invention, the described shared weight percent of the each composition of modified EVA resin and plastic is specially ethylene-vinyl acetate copolymer and accounts for 87.9%, chloroprene rubber accounts for 0.9%, paracril accounts for 0.5%, diatomite accounts for 7.8%, dicarboxylic acid ethyl-methyl phosphoric acid ester accounts for 1.6%, and mercaptopropyl trimethoxysilane accounts for 1.3%.
In a preferred embodiment of the present invention, the described shared weight percent of the each composition of modified EVA resin and plastic is specially ethylene-vinyl acetate copolymer and accounts for 84.7%, chloroprene rubber accounts for 1.6%, paracril accounts for 1.2%, diatomite accounts for 8.3%, dicarboxylic acid ethyl-methyl phosphoric acid ester accounts for 2.3%, and mercaptopropyl trimethoxysilane accounts for 1.9%.
The invention has the beneficial effects as follows: modified EVA resin and plastic of the present invention is by adding multiple additives in EVA resin, the modified EVA resin and plastic that makes to make has that chemical proofing is good, oil-proofness is good, intensity is high, toughness is large, the feature of good flame resistance and good product quality.
