Abstract

The invention relates to single-component waterproof high-hardness water-based floor paint and a preparation method thereof. With the combination of a modified pure acrylic emulsion and a modified silicone acrylic emulsion, not only can the weather resistance be improved, but also certain hardness can be enhanced; a good waterproof effect is also achieved; secondly, polycarbodiimide is also introduced into the formula, so that emulsion crosslinking is effectively promoted, drying rate is accelerated, and adhesive force is improved; and thirdly, the materials are different from sodium silicateor potassium silicate used by common floor paint. The lithium silicate adopted by the invention has the advantages that the modulus is 3.5, the possibility of efflorescence is reduced to the maximum extent, the stability is better, and most importantly, the overall strength and wear resistance are improved. And finally, in order to solve the problem of storage stability of a traditional silicate system, the water glass stability is introduced, so that the reaction of the water glass and the emulsion can be effectively prevented, the coexistence effect is achieved, and the problem of storage stability of the system is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of floor paint, in particular to a one-component waterproof high-hardness water-based floor paint and a preparation method thereof. Background technique [0002] The existing floor paints are mainly oil-based, and the oil-based paints are divided into epoxy, polyurethane and polyurea. These floor paints all contain harmful substances and do not meet the current environmental protection requirements. Poor weather resistance, not suitable for outdoor use. So the water-based floor paint was born, but the current water-based floor paint has the disadvantages of low hardness, poor wear resistance, poor weather resistance, easy to efflorescence, and water resistance. Compounding various additives can effectively solve the problems of poor water resistance, low hardness and poor wear resistance. SUMMARY OF THE INVENTION [0003] 1. The technical problem to be solved by the invention [0004] The purpose of the...
