Abstract

The invention belongs to the field of special paint, and discloses water-based high-clarity high-scratch-resistance five-splitting main finish paint. The water-based high-clarity high-scratch-resistance five-splitting main finish paint comprises the following components in parts by weight: 70 to 80 parts of hydroxyl acrylic emulsion, 5 to 10 parts of nano silicon sol, 4 to 8 parts of glass powder/aluminum oxide and an appropriate amount of pH regulator, thickening agent and water for adjusting the system to the appropriate viscosity and pH value; and the hydroxyl value of the hydroxyl acrylicemulsion is 3. The water-based high-clarity high-scratch-resistance five-splitting main finish paint has the advantages of rapidness in curing, good water resistance and scratch resistance.

Description

technical field [0001] The invention relates to the field of special coatings, in particular to a water-based high-definition, high-transparency, high-scratch-resistant, five-splitting clear surface main paint, a preparation method and a two-component clear top paint. Background technique [0002] CN201610360100.4 discloses a hydroxyacrylic acid emulsion for outdoor water-based wood coatings and a preparation method thereof. The preparation method is as follows: 1. Weigh deionized water, co-emulsifier, sodium carbonate, and emulsifier into the reactor, and stir at a constant speed ; 2. Fill the reactor with nitrogen and raise the temperature to 80°C; 3. Add the initiator solution into the reactor; 4. Weigh a certain amount of alkyl methacrylate, styrene, n-butyl acrylate ester, trimethylolpropane triacrylate and co-emulsifier, and added into the reactor through the monomer dropping tank; 5, weigh a certain amount of n-butyl acrylate, styrene, co-emulsifier, molecular weight ...
