Environment-friendly high-strength stone-plastic board and preparation method thereof

Abstract

The invention discloses an environment-friendly high-strength stone-plastic board. The environment-friendly high-strength stone-plastic board comprises the following raw materials in parts by weight: 10-16 parts of marble powder, 8-12 parts of fly ash, 10-14 parts of volcanic ash, 6-10 parts of talcum powder, 17-27 parts of polyethylene, 8-10 parts of chlorinated polyethylene, 4-6 parts of nano-sized titanium dioxide, 2-4 parts of nano-sized zinc oxide, 2-5 parts of a lubricant, 2-3 parts of a plasticizer, 1-3 parts of a stabilizer, 2-4 parts of an antistatic agent and 3-5 parts of a silane coupling agent. The environment-friendly high-strength stone-plastic board combines the advantages of stone and plastic, not only has the appearance like natural stone, but also is relatively light in weight, relatively high in strength, anti-static, non-friable and relatively environment-friendly; meanwhile, according to a preparation method of a sealing material provided by the invention, raw material components are safe, reliable, harmless to the environment and easy to obtain, the cost is relatively low, the process is succinct, the operation is easy and the industrial production is easily implemented, so that the preparation method has a relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly high-strength stone-plastic plate and a preparation method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. yes [0003] Homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80-85°C, and becomes viscoelastic at 130°C , 160 ~ 180 ℃ began to change into a viscous flow state; good...

Problems solved by technology

[0004] On the other hand, in the field of building panels, the commonly used bottom panel materials can be divided into the following types: wooden panels, natural stone, wood-plastic materials, ceramic tiles, etc., but in practical applications, it is found that the above-mentioned materials have their own defects in use. For example: wooden boards have poor moth-resistance, cannot be fire-proof and moisture-proof, and have poor thermal conductivity; ceramic tiles are fragile and cold in texture; The texture is cold; wood-plastic materials contain organic binders and other chemical substances, which are prone to produce small molecule harmful gases when used in indoor environments

With the development of nature by humans, natural stone resources are becoming less and less, and the mining of natural stone is becoming more and more difficult. Natural stone is difficult to process, fragile, requires a lot of water, and is easy to cause environmental pollution. , therefore, there is an urgent need to develop an artificial stone material that can replace natural stone
