A kind of nucleating agent polypropylene high-performance composite additive and preparation method thereof

Abstract

The invention discloses a nucleating agent polypropylene high-performance compound additive which comprises the following components in percentage: 45-55% of nano nucleating agent, 5-10% of fluorine-containing polymer, 20-30% of antioxidant, 2-6% of antibacterial agent, 5-10% of dispersing agent and 3-10% of calcium stearate. The nucleating agent polypropylene high-performance compound additive has the characteristics of multiple functions, safety, environmental-friendliness and high specificity, and a plastic product with the additive has multiple excellent properties.

Description

technical field [0001] The invention belongs to the technical field of plastic additives, and in particular relates to a nucleating agent polypropylene high-performance compound additive and a preparation method thereof. Background technique [0002] There are many defects in the existing plastics. Take the domestic M30RH and K9927 as examples. Although they are strong in rigidity, their toughness is poor, and they are easily damaged when used as the inner tub of a washing machine under high-speed impact; the temperature resistance is not strong, especially under low temperature conditions. The texture is brittle, and it is easy to crack when used as a refrigerator liner; it has no anti-mildew and antibacterial function, and it is easy to infect skin, gastrointestinal and other diseases; it also has high haze and low light transmission rate, which affects the use effect; it is not easy to release the mold during processing, which is serious It will directly damage the proces...

AI Technical Summary

Problems solved by technology

[0003] At present, the usual PP additives also have the following main problems: (1) The modification effect is general

There is a difficult technical problem: if the rigidity of PP is increased, the toughness will decrease, and if the toughness is increased, the rigidity will be insufficient. In addition, it is difficult to improve the main technical indicators such as heat resistance and low temperature impact strength simultaneously.

(2) Single function

To change the performance of PP in many ways, it is often necessary to open multiple feeding holes at the same time to add a variety of modifiers with different functions, which not only increases the difficulty of the process, but also increases the hidden dangers of equipment failure, but also increases the production cost and reduces labor efficiency.

(3) More powder

At present, some modifier products are still in powder form. During the production process, they are easy to hang on the wall when storing materials, easy to raise dust when feeding materials, easy to block (bridge) when feeding materials, and large material loss, which not only causes pollution, but also affects the health of workers. , also make the measurement inaccurate, directly affect the product quality
