Problems solved by technology

Now marine lifejackets generally use EVA foam material as buoyancy material, and when producing EVA foam material, static electricity is often generated, which seriously threatens people's safety; at present, AC foaming agent is generally used in EVA foam, but AC foam The decomposition temperature of the agent is high, and the resilience of the prepared EVA foam material is not high, and the softness is poor. At the same time, most of the EVA foam materials currently on the market do not have antibacterial function.

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 [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antibacterial EVA foam material. Background technique [0002] Ethylene-vinyl acetate copolymer, abbreviated as EVA in English, has been widely used in sports equipment, life-saving equipment, household products and other fields due to its excellent coloring performance and good flexibility since its inception. [0003] A life jacket is a life-saving garment designed similar to a vest, made of nylon fabric, neoprene, buoyancy material, inflatable material or reflective material, etc. It has enough buoyancy to wear on the body, so that the head of the person who falls into the water can be exposed The water surface is one of the life-saving equipment on ships and aircrafts. Now marine lifejackets generally use EVA foam material as buoyancy material, and when producing EVA foam material, static electricity is often generated, which seriously threatens peop...
