Problems solved by technology

[0003] In recent years, with the rapid development of the electronics industry, a large number of integrated circuits, components and their products are packaged with cheap and high-quality film materials. However, the existing degradable plastic film packaging materials generally do not have antistatic properties. Film packaging that generates static electricity, the film will accumulate static electricity due to electromagnetic induction and friction, and generate high-voltage discharges to various sensitive electronic components, instruments, etc., causing damage to the packaged goods and causing great economic losses

Abstract

The invention discloses an anti-electrostatic degradable film material and a preparation method thereof. The film material is prepared from the following raw materials: LDPE, LLDPE, starch-based degradable plastic materials and anti-electrostatic master batch. The preparation method comprises the following steps: uniformly mixing the raw materials at a high speed; and obtaining a product by extruding, swelling and stretching. The anti-electrostatic degradable film material has good anti-electrostatic effect, is degradable and does not pollute the environment; and the preparation method of the anti-electrostatic degradable film material has simple process and low cost and can prepare finished products with good quality.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a plastic film and a preparation method thereof, in particular to an antistatic degradable film material and a preparation method thereof. Background technique [0002] Degradable plastics not only have the functions and characteristics of traditional plastics, but also can be split, degraded and reduced in the natural environment under the action of microorganisms in soil and water, or through the action of ultraviolet rays in sunlight, and finally re-enter the ecological environment in a non-toxic form. , back to nature. Among the degradable plastics, the biodegradable plastics made of aliphatic polyester are the most promising. Aliphatic polyesters mainly include polycaprolactone (PCL), polybutene (PBS) and copolymers synthesized from petroleum, as well as polylactic acid produced from renewable resources and polyhydroxybutyric acid produced by microorganisms. (PHB),...
