Abstract
The invention relates to an antibacterial EVA (Ethylene-Vinyl Acetate) foam material belonging to the technical field of high-molecular materials. The antibacterial EVA foam material comprises the following components in parts by weight: 80-100 parts of EVA copolymers, 5-10 parts of ethylene-propylene copolymers, 6-12 parts of polyolefin elastomer, 0.5-1 part of a crosslinking agent, 0.5-1 part of barium stearate, 10-15 parts of a microcapsule foaming agent, 5-8 parts of antistatic agent, 1-3 parts of nanometer titanium dioxide and 2-4 parts of chloroxylenol. The antibacterial EVA foam material provided by the invention is soft in texture, smooth in surface, good in rebound vibration resistant effect, favorable in antibacterial and antistatic functions and relatively wide in application range, not only can be used for manufacturing life-saving devices, but also can be used in other fields such as packaging materials and the like.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of antibacterial EVA foamed material.
Background technology
Ethylene-vinyl acetate copolymer, the English EVA that is called for short, since coming out, with good tinctorial property and good flexibility, and has been widely used in the fields such as sports equipment, buoyant apparatus, household articles.
Vestlifejacket is a kind of clothes of giving first aid to life, design class is like vest, adopt nylon facing material, chloroprene rubber, buoyancy material, inflatable material or light reflecting material etc. to be made, be through and there is enough buoyancy with it, drowning people's head can be surfaced, and is one of survival equipment on ship, on aircraft.It is buoyancy material that present sea generally adopts EVA foaming material with vestlifejacket, and in the time producing EVA foam material, often can produce static, serious threat people's safety; General employing AC whipping agent when EVA foaming at present, but AC foaming agent decomposition temperature is higher, the EVA foam material rebound resilience making is not high, and flexibility is poor, and meanwhile, EVA foam material major part in the market does not have antibacterial.Therefore how overcoming the deficiencies in the prior art is problems that current technical field of polymer materials is needed solution badly.
Summary of the invention
The object of the invention is, in order to solve the deficiencies in the prior art, provides a kind of antibacterial EVA foamed material, its surface smoothing, and resilience anti seismic efficiency is good, and has good antibacterial and anti-static function.
The technical solution used in the present invention is as follows:
A kind of antibacterial EVA foamed material, comprises the following component according to parts by weight meter: 80 ~ 100 parts of ethylene-vinyl acetate copolymers, 5 ~ 10 parts of ethylene-acrylic acid copolymers, 6 ~ 12 parts of polyolefin elastomers, 0.5 ~ 1 part of linking agent, 0.5 ~ 1 part of barium stearate, 10 ~ 15 parts of microcapsule foamers, 5 ~ 8 parts, static inhibitor, 1 ~ 3 part of nano titanium oxide, 2 ~ 4 parts of PCMXs.
Described static inhibitor is glyceryl monostearate.
Described linking agent is crosslink agent DCP.
The preparation method of antibacterial EVA foamed material of the present invention adds mixing roll mixing above-mentioned raw materials simultaneously, obtains batch mixing material, then mixing material upper and lower surface is covered after polyester film to compression molding on vulcanizing press; Sample after moulding is placed in dull and stereotyped upper foaming, removes polyester film after cooling.
compared with prior art, its beneficial effect is in the present invention:antibacterial EVA foamed material quality softness of the present invention, surface smoothing, resilience anti seismic efficiency is good, and has good antibacterial and anti-static function, and range of application is wider, not only can be used for manufacturing buoyant apparatus, also can be used for other field, as wrapping material field etc.
