Problems solved by technology

However, the starch molecular chain contains a large number of hydroxyl groups, which are easy to form hydrogen bonds inside and outside the molecular chain, so it is insoluble, infusible, and has poor water resistance. It is easy to absorb water when exposed to water or stored in humid air for a long time, affecting its stability. sex

Abstract

The invention discloses an uvioresistant laminated plastic film. The uvioresistant laminated plastic film is prepared from, by weight, 65-75 parts of polypropylene, 45-55 parts of corn starch, 4-5 parts of montmorillonite, 10-16 parts of bamboo charcoal powder, 4-8 parts of plasticizer, 5-7 parts of fish glue from scale, 8-15 parts of collagenous fibers, 2-5 parts of elastomer, 5-8 parts of polylactic acid, 3-8 parts of plant fibers, 5-10 parts of nano titanium dioxide, 5-10 parts of waterproof agent, 3-6 parts of tea polyphenols, 6-12 parts of peroxide and 2-7 parts of antistatic agent. The adopted corn starch is rich in sources, low in cost and environment friendly, the prepared plastic film is high in strength, low in production cost, biodegradable and antistatic, and white pollution can be mitigated. By the aid of the characteristics of ultraviolet shielding of montmorillonite and oxidation resistance of tea polyphenols, the film is good in ultraviolet resistance and oxidation resistance, and rate of ultraviolet shielding is over 96%; as bamboo charcoal powder is added in the formula, a lot of negative ions can be released, and the plastic film is strong in odor adsorbability, antibacterial property and deodorization capability.

Description

technical field [0001] The invention relates to the field of plastic films, in particular to an anti-ultraviolet composite plastic film. Background technique [0002] With the vigorous development of the plastic industry, the environmental pollution caused by waste plastic film garbage is becoming more and more serious, and white pollution has become a global environmental problem. Therefore, people must intensify their efforts to develop biodegradable plastic films to control the environmental pollution caused by plastic waste. [0003] Starch is a natural polymer material with abundant sources and low price. It is also an inexhaustible renewable resource. It can be biodegraded under various environmental conditions. The final degradation products carbon dioxide and water can It is recycled through photosynthesis of plants without causing any pollution to the environment. However, the starch molecular chain contains a large number of hydroxyl groups, which are easy to for...
