Novel anticorrosive, moisture-resistant and flame-retardant IXPC material and preparation method thereof

Abstract

The invention relates to a novel anticorrosive, moisture-resistant and flame-retardant IXPC material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 20 to 40 parts of plastic grains, 25 to 35 parts of modified resin, 12 to 18 parts of nitrile rubber, 0.1 to 0.4 part of a cross-linking agent, 1 to 5 parts of a stabilizing agent, 0.1 to0.3 part of a foaming agent, 18 to 30 parts of a filling material, 0.1 to 0.3 part of a ripening agent, 0.2 to 0.4 part of a lubricant and a proper amount of a pigment. The material is prepared through the following steps: subjecting components except for the cross-linking agent and the foaming agent to uniform mixing under full stirring, placing an obtained mixture into an internal mixer, then adding the cross-linking agent and the foaming agent, carrying out internal mixing, then carrying out open milling so as to obtain a thin sheet, placing the thin sheet into a foaming machine, and carrying out foaming. Compared with the prior art, the preparation method provided by the invention prepares a product with property characteristics similar to the property characteristics of a natural wood material; and the material can adjust various softness, hardness, weight and thickness according to the needs of the product, can be shaped by heating through a mold, has excellent anticorrosive, moisture-resistant and flame-retardant characteristics, and thoroughly solves problems like insusceptibility to damping and mildewing, corrosion prevention and flammability in the use process of a traditional wood plate.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and relates to a novel anti-corrosion, moisture-resistant and flame-retardant IXPC material and a preparation method thereof. Background technique [0002] In recent years, due to the continuous reduction of timber resources in the world, the reduction of timber resources in our country is faster. On the other hand, with the improvement of people's living standards, people have higher and higher requirements for the quantity and quality of timber utilization. However, the timber resources that our country can provide at present are very limited, therefore, the contradiction between supply and demand of timber resources is becoming increasingly prominent. Nowadays, plastic imitation wood materials have become a new field of research and development. Plastic imitation wood products have the characteristics of harmless to human body, no cracking and deformation, no mold, no pollution...

AI Technical Summary

Problems solved by technology

However, in actual use, the products made of existing plastic imitation wood materials still have the following deficiencies: 1) easy to deform under long-term storage; 2) easy to absorb moisture and cause frost and white under long-term storage; It is easy to harden and crack or crack under long-term storage. 4) Poor flame retardancy

Although the technical solution disclosed in this patent takes into account the tensile strength and bending strength of the material, the material is susceptible to moisture and corrosion, and its flame retardancy is poor, which needs further improvement
