Problems solved by technology

However, the flame retardancy of ASA is poor, and the addition of flame retardants will sharply reduce the toughness of ASA materials, make the materials brittle, and reduce the service life
At the same time, its wear resistance and anti-adhesion are poor, and the comfort during use is poor.

Abstract

The invention provides an ASA co-extruding material with flame resistance and high weather resistance and relates to the technical field of macromolecules. The ASA co-extruding material with flame resistance and high weather resistance provided by the invention comprises the following components in parts by weight: 20-32 parts of ASA powder, 62-70 parts of medium flow styrene acrylonitrile resin,8-12 parts of low flow styrene acrylonitrile resin, 20-30 parts of ethylene ditetrabromide phthalimide, 6.2-9.3 parts of auxiliary fire retardant and 10-15 parts of water-based wear-resisting agent. The ASA co-extruding material has excellent flame resistance, high wearing resistance, high surface evenness and high heat stability; ASA powder, medium flow styrene acrylonitrile resin and low flow styrene acrylonitrile resin are compounded and prepared into a base stock resin, so that liquidity is moderate, impact property is excellent and melt strength is higher; an anti-flaming plasticizer is added, so that fire-resistant temperature and capacity of resisting against high-temperature corrosion deformation of the product are promoted; the water-based wear-resisting agent is added for obviously improving the surface performance of system, so that the wearing resistance, smoothness and anti-adhesion property of the coating can be obviously promoted.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a flame-retardant high-weather-resistant ASA co-extrusion material. Background technique [0002] At present, the sub-board co-extruded layers of various construction industries have been made of plastics and wood flour. These boards have poor high temperature resistance, are easy to vitrify and break in high temperature environments, and have a short service life. Generally, they only need to be replaced every 3-5 years, which increases the cost of use, and the aging speed is fast, easy to fade, and cannot be recycled. use. [0003] ASA resin is a ternary graft copolymer composed of acrylonitrile, styrene, and acrylate. It is an amorphous polymer formed by grafting and copolymerizing acrylonitrile and styrene monomers with polyacrylate as the main chain. ASA was first industrialized by BASF in Germany in 1962, followed by Hitachi Chemical in Japan. ASA is an opaque yellow am...
