Long-acting and weather-proof resin tile co-extrusion material with light screening function and preparation method thereof

Abstract

The invention discloses a long-acting and weather-proof resin tile co-extrusion material with a light screening function. The co-extrusion material comprises the following raw materials: ASA resin, ASresin, modified montmorillonite, a light screener, a hindered amine light stabilizer, an ultraviolet light absorber, an antioxidant, EBS and toner. The modified montmorillonite is prepared in the following steps: dissolving sodium hexametaphosphate into water to form homogeneous solution and adding montmorillonite, so as to obtain suspension liquid; performing ultrasonic dispersion on the suspension liquid, allowing standing still for layering and performing vacuum spray drying on an upper-layer matter, so as to obtain a prefabricated material; dissolving the prefabricated material into methylbenzene, rising the temperature, dropping in a treating agent and stirring the mixture for reaction, so as to obtain primary modified montmorillonite; dissolving the primary modified montmorilloniteinto methylbenzene, performing ultrasonic dispersion, adding an initiator under a protective atmosphere, slowing dropping in a monomer MMA (methyl methacrylate), rising the temperature and stirring the mixture for reaction, so as to obtain the modified montmorillonite. The prepared resin tile co-extrusion material is excellent in ultraviolet aging resistance, long in service life and good in mechanical property.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a long-acting weather-resistant resin tile co-extrusion material with light shielding function and a preparation method thereof. Background technique [0002] As a building material for waterproof, heat preservation and heat insulation, clay tile is one of the building materials that we use more and has a long history. However, this kind of tile needs to consume a lot of clay. In order to protect cultivated land, protect the environment, save energy, my country has gradually restricted or even banned the use of clay tiles. At present, more and more synthetic resin tiles have been applied to buildings. Synthetic resin tile is a new type of building material developed by using high-tech chemical and chemical technology. Pollution, green environmental protection, fire prevention, insulation, easy installation, etc., and the shape is beautiful and three-dimensional, and the co...

Problems solved by technology

Among them, ASA resin has poor anti-ultraviolet aging performance in outdoor conditions. Therefore, in order to improve the anti-ultraviolet aging performance of ASA resin, light stabilizers are often added. However, adding a small amount cannot effectively improve the anti-ultraviolet aging performance of ASA, while a large Adding a light stabilizer will significantly reduce the mechanical properties of the material
