Problems solved by technology

In order to meet the requirements of certain mechanical properties and high flame retardancy, flame retardants and fillers are generally added in large amounts, and these added components are usually not well compatible with PVC resins. On the other hand, due to these The synergistic effect between the additives has not been properly exerted, and a large amount of additives is required to achieve the desired effect, resulting in a greatly reduced processing flow performance of the final PVC composite.
It can be seen from the prior art that in the process of polyvinyl chloride modification, improving its flame retardancy and improving its fluidity are mutually restraining solutions. If the flame retardancy is improved, the fluidity will decrease, and if the fluidity is improved, then Reduced flame retardancy

Abstract

A nanometer polyvinyl chloride plastic is characterized by comprises the following raw material compositions in parts by weight: 80-90 parts of polyvinyl chloride, 30-60 parts of a flame retardant plastic additive, 5-6 parts of barium stearate, 2-4 parts of calcium stearate, 4-5 parts of a brominated flame retardant, 10-15 parts of an auxiliary agent, wherein the flame retardant plastic additive comprises the following compositions in parts by weight: 25-30 parts of antimony trioxide, 15-20 parts of zinc borate, 60-80 parts of phosphotriester, 10-20 parts of tetrabromobutane, 1-5 parts of epoxy chloropropane and the like.

Description

technical field [0001] The invention relates to a plastic, especially a high flame-retardant polyvinyl chloride plastic. Background technique [0002] Due to the increasingly wide application of plastics, such as electronics, military industry, daily chemical and other industries, these industries have very high requirements for flame retardancy. Generally, it is required to add flame retardants in the plastic production process to achieve the purpose of flame retardancy. Currently, in the plastic production process Generally, single flame retardant additives such as alumina trihydrate and antimony trioxide are added to the product. Excessive addition of these single flame retardant additives can affect certain properties of the finished product, and too little addition will not result in flame retardant effects. Therefore, the synergistic formulation of flame retardants has become an important topic for in-depth research by technicians in this industry. [0003] Polyvinyl ...
