Description
Technical Field
The invention relates to the field of high polymer materials, in particular to a film opening agent, a modified ethylene propylene rubber film and a composition for forming the film opening agent and the modified ethylene propylene rubber film.
Background
The opening agent, also called slipping agent, anti-blocking agent, etc. is commonly used in the production and preparation process of plastic film material products to ensure that the film layers are not adhered and have good opening performance. The earliest opening agents were inorganic talc and diatomaceous earth, etc.; the medium-term development is to organic oleamide, erucamide, EBS derivatives and the like; at present, the synthetic silicon dioxide is widely applied to films as an opening agent.
The oleamide/erucamide is a raw material processed by using vegetable oil as a raw material, and has the appearance of small particles (small crystals) without peculiar smell. The resin has good compatibility with resin, is stable to heat, oxygen and ultraviolet rays, has a typical polar and nonpolar molecular structure, can form a monomolecular film on a material interface, and has the effects of adhesion resistance, smoothness, leveling, water resistance, moisture resistance, precipitation resistance, pollution resistance, static resistance, dispersion and the like. 0.1-0.5 of oleamide is added into the low-density polyethylene film material, so that the antistatic and lubricating properties and the moisture-proof properties can be improved; meanwhile, the addition of the oleamide can also obviously reduce the friction coefficient and the bonding resistance, obviously improve the benefit during film blowing (extrusion molding), effectively prevent the bonding between films and the caking between granules, increase the smoothness of the surfaces of the films, prevent the deposition of dust on the surfaces of products, and produce very smooth plastic finished products.
The silicon dioxide opening agent is artificially synthesized amorphous silicon dioxide, is a high-efficiency anti-adhesion agent, an anti-caking agent and an opening agent, and is often used as a high-efficiency opening agent for polyolefin IPP films, polyethylene LDPE films and BOPP biaxially oriented polypropylene films. The silica opening agent exhibits a greater bulk density and is more easily mixed with the resin, facilitating processing operations. The silicon dioxide opening agent can be made into a master batch with the concentration of more than 20 percent, and the silicon dioxide opening agent is 100 percent of synthetic amorphous silicon dioxide, does not contain any silicon crystal, does not form silicosis, does not contain organic matters, and passes the FDA certification. When the silicon dioxide opening agent is applied to a film, the addition of the silicon dioxide opening agent allows a customer to reduce the addition amount of the amide slipping agent, so that an excellent opening effect can be obtained, and the static/dynamic friction force reduction effect is obvious. In the film, the silicon dioxide opening agent is added to have very small influence on the haze rise of the film, the transparency is high, and the phenomenon of terminal yellowing is effectively improved.
However, the film prepared by the film opening agent still has the defects that the adjacent film layers are adhered and are not easy to open.
