Abstract

The invention provides high-weather-resistance ASA special for PVC resin tiles, and relates to the technical field of engineering plastic production and manufacturing. The high-weather-resistance ASA special for PVC resin tiles comprises the following raw materials in parts by weight: 70-90 parts of styrene, 10-30 parts of acrylonitrile, 2-5 parts of alkylphenol phosphate esters and 1-3 parts of a nonionic emulsifier, and the alkylphenol phosphate esters and the nonionic emulsifier are compounded and emulsified, and styrene and acrylonitrile are sequentially added into a polymerization reaction device to carry out core-shell emulsion polymerization, and polymerization reaction is conducted to obtain the product. The weather resistance of ASA can be greatly improved, and the polymerization reaction is accelerated and thorough through the polymerization reaction device.

Description

technical field [0001] The invention relates to the technical field of engineering plastics production and manufacturing, in particular to high weather resistance ASA for PVC resin tiles. Background technique [0002] The main component of PVC resin tile is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. It is a well-loved, popular and widely used synthetic material in the world today. Its global usage ranks second among various synthetic materials. PVC is polyvinyl chloride plastic, which is bright in color, corrosion-resistant, and durable. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process , so its products generally do not store food and medicines. In the prior art, PVC resin materials will be used in the construction industry to produce PVC resin tiles. PVC resin tiles have good plasticity. In order to increase their weather resistan...
