example 1

[0035] 1. Preparation of MMA resin prepolymer

[0036] The methyl methacrylate of 20g, the butyl acrylate of 10g, the acrylic acid of 4g and the benzoyl peroxide of 0.04g are joined in the four-necked flask that thermometer, condenser, stirrer are equipped with, water bath heating, temperature is controlled at 85°C, heat preservation reaction for 2 hours to make MMA resin prepolymer, set aside.

[0037] 2. Preparation of MMA floor coating

[0038] The prepolymer of 28g is poured in the beaker, after diluting with the methyl methacrylate of 12g and butyl acrylate of 12g, add talcum powder 13g, plasticizer 8g, defoamer 4g, wax liquid 4g, initiator 8g, 4g of curing accelerator, fully stirred for 5 minutes to obtain a coating. In the absence of air bubbles, the paint was injected into the previously prepared mold and allowed to cure to a 2 mm thick coating within 1 hour at room temperature.

Abstract

The invention relates to a methyl methacrylate(MMA) floor coating capable of rapidly solidifying. The methyl methacrylate(MMA) floor coating capable of rapidly solidifying can be prepared by two steps. First of all, according to a certain proportion, methyl methacrylate(MMA), butyl acrylate (BA), acrylic acid (AA) and benzoyl peroxide (BPO) are put into a reactor provided with a thermometer, a condenser and a stirrer for water bath heating to prepare an acrylate prepolymer for standby use; then at room temperature, a proper amount of the acrylate prepolymer is dissolved and diluted with a certain amount of MMA and BA, talcum powder, liquid wax, an auxiliary agent, an initiator and a solidifying accelerator are added, and fully stirred to obtain the floor coating, and the floor coating is prepared on site during construction, and can solidify 1 hour after the pavement. The MMA floor coating is short in solidifying time, less affected by temperature, excellent in performance, green, environmentally friendly, and wide in adaption field.

Description

technical field [0001] The invention belongs to the field of building materials. In particular, it relates to a fast-curable MMA floor coating. Background technique [0002] MMA floor coating is a new type of floor made of acrylic MMA prepolymer as the main resin base material, MMA, BA and other monomers as crosslinking agents, adding inorganic fillers such as talcum powder, high melting point wax liquid and additives. Paving materials. [0003] MMA floor coatings have the generality of traditional floor coatings, but also have unique properties that other coatings do not have. Traditional floor coatings in my country generally require above zero or five degrees to be cured normally, which limits the application in northern my country. Moreover, the curing time is relatively long, and it can be completely cured after about 2 days, which is easy to crack. The curing and crosslinking reaction of MMA floor coatings is a free radical polymerization reaction, which is slightl...
