Problems solved by technology

Although this invention uses water as a solvent to meet the requirements of environmental protection, the base material used in this invention is styrene-acrylic emulsion, so the defects such as high-temperature stickiness and low-temperature brittleness of the produced rock slices are still unavoidable, and the produced rock slices are packaged before transportation. It is easy to agglomerate and stick together on the way, so the rock flakes can only be soaked in emulsion and water, packaging and transportation will increase the customer's use and transportation costs, and because the rock flakes based on styrene-acrylic resin have poor elasticity, it will affect a large number of popularization and application in the market
[0005] To sum up, there is no environmentally friendly colored rock flake with excellent elasticity, good color retention, aging resistance, acid and alkali resistance, and non-sticking during transportation. It is packed in ordinary paper bags and does not need to be soaked in Emulsion and water, thus saving a lot of packaging costs and transportation costs, a product with an ideal cost performance

Abstract

The invention relates to a preparation method for a dry-type water colored sliver, comprising following technical steps: 1) preparation of polyurethane modification acrylic acid latex: dihydric alcohol is put into a reactor and then temperature is increased to 70 DEG C to 100 DEG C, then dihydric alcohol and organic tin dihydric alcohol is added and temperature is increased to 100 DEG C +/- 5 DEG C for 2 to 4 hour reaction, then temperature is decreased to 60 DEG C +/- 5 DEG C and methyl acrylate and dihydroxy methylpropanoic acid are added, then circumfluence temperature is controlled at 60 DEG C to 80 DEG C and reaction is carried out for 6 hours +/- 0.5 hours; when NCO value in reaction system is lower than 1, prepolymer is transferred into a dispersator and is dispersed in water dissolved in neutralizing agent of triethylamine, then water polyurethane is prepared; 50 to 100 pieces of water polyurethane are put into a reactor, temperature is increased to 70 DEG C to 90 DEG C and polyurethane modification acrylic acid co polymerization latex is obtained: step 2, the preparation of dry-type water colored sliver. The dry-type water colored sliver of the invention has the advantages of fine climate resistance performance, no conglutination on the way of transportation, fine elasticity, no discharging of organic matter with volatility and cost saving.

Description

(1) Technical field [0001] The invention relates to a preparation method of dry water-based colored rock flakes, which can be widely used as paint decoration for interior and exterior walls of buildings, granite paint and the like. It belongs to the field of chemical building materials. (2) Background technology [0002] At present, the rock chip industry is mainly based on wet rock chips. Due to the disadvantages of high temperature stickiness and low temperature brittleness, dry rock slices are easy to agglomerate and stick during packaging and transportation, so dry rock slices can only be packaged and transported by soaking in emulsion and water. The use and transportation costs of wet rock slices are very high. In the past, the poor elasticity of rock slices affected the popularization and application in the market. [0003] The invention patent application with application number 200810060085.7 provides a non-adhesive, non-fading colored rock flake and its preparatio...
