A kind of polyethylene masterbatch composite auxiliary agent and preparation method thereof

Abstract

The invention discloses a polyethylene master batch compound additive and a preparation method thereof. The polyethylene master batch compound additive is prepared from the following components: 1 to 10% of nanometer fully-vulcanized powdered silicone rubber, 18 to 25% of nanometer silica, 1 to 8% of a dispersant, 1 to 8% of an organosilicon active flow aid, 1 to 5% of a fluorine-containing polymer, 3 to 5% of an anti-oxidant 168, 3 to 5% of an anti-oxidant 1010, 1 to 4% of an antistatic agent, 1 to 4% of an ultraviolet ray absorber and 50 to 60% of a PE carrier resin. The polyethylene master batch compound additive has the characteristics of a great number of functions, safety, environment friendliness and strong exclusiveness and enables a plastic product to have multiple excellent performances.

Description

technical field [0001] The invention belongs to the technical field of plastic additives, and in particular relates to a polyethylene masterbatch compound additive and a preparation method thereof. Background technique [0002] my country's total plastic production and product consumption both rank second in the world. Among them, polyethylene (PE) has the largest output, the fastest development and the most active variety development among synthetic resins. Because PE has excellent low temperature resistance, chemical stability, most acid and alkali corrosion resistance, electrical insulation properties, etc., and because of its light weight and easy processing, the production of PE has developed rapidly. [0003] According to statistics, the total national PE output in 2012 was about 10 million tons. Since the new polyethylene projects in the Asia-Pacific region are mainly located in China, India and South Korea in the next period of time, it is expected that the total do...

AI Technical Summary

Problems solved by technology

However, at present, some brands of additives are often modified only for one of the functions. To change the performance of PE in many ways, a variety of additives with different functions are often added at the same time. It is necessary to open multiple feeding systems at the same time, which makes the operation complicated and affects Product quality, increase production cost, but also reduce production efficiency

[0008] 2) The method is backward

For example, in order to solve the phenomenon of thin film adhesion, the method of directly adding anti-adhesion agent in the manufacturing process of the film is generally adopted. Although the purpose of reducing the surface friction coefficient is also achieved, because the anti-adhesion agent is in the form of inorganic powder, it has unique characteristics of fine microstructure. Particle size distribution, direct addition will easily cause uneven dispersion of anti-blocking agent in the resin matrix, thus affecting the optical and mechanical properties of the film product

[0009] 3) At present, some domestic additives: such as antioxidants, slip agents, etc. are still in powder form, and users are prone to dust during feeding, wall hanging when storing materials, and blockage (bridging) when adding materials. Material loss is large, which not only causes pollution, but also easily makes measurement inaccurate, directly affecting product quality

[0010] At present, there is no auxiliary agent that can effectively overcome the above-mentioned difficulties at the same time
