White marble sand modified sol resin material and preparation method thereof

Abstract

The invention discloses a white marble sand modified sol resin material. The white marble sand modified sol resin material is prepared from the following raw materials in parts by weight: 60 to 70 parts of polypropylene, 20 to 30 parts of white marble sand, 14 to 20 parts of ethyl orthosilicate, 3 to 5 parts of iso-octyl acrylate, 1 to 2 parts of hexamethyl phosphoryl triamide, 5 to 7 parts of allyl alcohol, 1 to 2 parts of pyromellitic acid dianhydride, 0.4 to 1 part of 2-thiol benzimidazole, 1 to 2 parts of fatty acid polyglycol ester, 2 to 4 parts of aluminum stearate, 0.1 to 0.2 part of bisphenol a diglycidyl ether, 0.4 to 1 part of polyacrylamide, 2 to 3 parts of hydrogenated castor oil and 10 to 12 parts of 6% to 7% of ammonium hydroxide. According to white marble sand modified sol resin material, sol is sufficiently organized with a compound filler of white marble sand, so that the compatibility of the compound filler in resin is effectively improved, the aggregation is effectively reduced, and the stability strength of the finished product is improved.

Description

technical field [0001] The invention belongs to the field of white marble sand, and in particular relates to a white marble sand modified sol resin material and a preparation method thereof. Background technique [0002] The main component of white marble is calcium carbonate, which is mainly composed of CaCO3, MgCO3 and SiO2, and also contains a small amount of Al2O3, Fe2O3 and other components. It belongs to fine-grained marble with white color and hard quality. It is a first-class building and carving material. Basically it is not soluble in water. It can exist in the following forms: aragonite, calcite, chalk, limestone, marble, travertine, and can be found in rocks. The main component of animal back shells and snail shells. At the same time, it is also an important building material. White marble is hard and white. The Huabiao in front of Tiananmen Square, the Jinshui Bridge, the palace base, stone steps, and guardrails in the palace are all made of white marble. ...

AI Technical Summary

Problems solved by technology

[0003] White marble sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries; white marble sand is mostly Used as an organic resin filler, it can effectively improve the mechanical properties of the resin substrate. However, because it is an inorganic compound, it has poor compatibility with the resin matrix and easily forms agglomerations, which will affect the stability and strength of the finished composite material.
