Embodiment 1

[0030] 1. Preparation of polyfluorinated bisphenol A epoxy acrylate polymer:

[0031] Mix undecafluoro-n-hexan-1-ol (PFHOL) and dicyclohexylmethane diisocyanate (HMDI) with a molar ratio of 1:2, and react at 60°C for 3-5 hours under nitrogen protection, then add the mixture to dimethyl In methyl formamide (DMF) solution, obtain prepolymer solution until solution is clear and transparent;

[0032] Add bisphenol A epoxy acrylate (ACM) (the molar ratio of ACM to prepolymer is 2.07:1) into the prepolymer mixed solution, and the solid content of the solution after mixing is controlled at 85% (w / v), continue Stirring, under the protection of nitrogen, react at 60°C for 12-24h, and remove the solvent from the obtained mixed solution to obtain a polyfluorine-modified bisphenol A epoxy acrylate polymer for future use. The molecular structural formula of described polyfluorine modified bisphenol A epoxy acrylate polymer is as follows figure 1 shown.

Abstract

The invention relates to the technical field of building materials and particularly relates to super-hydrophobic artificial marble which is composed of following components, by weight: 100 parts of unsaturated polyester resin, 0.5-2 parts of a peroxide-type initiator, 0.1-2 parts of an accelerant, 5-30 parts of vinyl-type resin diluent, 5-30 parts of polyvinyl-type resin assistant crosslinker, 100-500 parts of ore slag micro powder, 10-30 parts of a flame retardant, and 3-15 parts of polyfluoro-modified bisphenol A epoxy acrylate polymer. In the invention, the polyfluoro-modified bisphenol A epoxy acrylate polymer, which has a super-hydrophobic function, is employed as a hydrophobic additive to prepare the artificial marble, so that the artificial marble is excellent in hydrophobic performance. A contact angle between the surface of the super-hydrophobic artificial marble and water is 150-170 degrees so that the surface of the super-hydrophobic artificial marble has an excellent self-cleaning function. In addition, the marble in deep color series is high in strength, is good in waterproof performance and is strong in corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a superhydrophobic artificial marble. Background technique [0002] With the development of my country's iron and steel industry, the discharge of blast furnace slag is increasing day by day. According to recent statistics from China United Iron and Steel Network, my country's crude steel output reached 782 million tons in 2013, and 0.3 to 1.2 tons of blast furnace slag was produced per ton of pig iron, which means that hundreds of millions of tons of blast furnace slag were discharged in 2013. Blast furnace slag powder is a scientific research achievement of iron and steel enterprises. It not only solves the pollution of blast furnace slag waste to the environment, but also uses blast furnace slag powder produced from blast furnace slag as raw material in the cement industry, achieving obvious economic benefits. The present invention intends to study the manufacture ...
