Abstract

The invention discloses a high-penetration sand-fixing primer, which is composed of the following components according to the ratio of parts by weight: 400-600 parts of water-based nano inorganic silicon resin, 300-500 parts of deionized water, 30-70 parts of potassium silicate, 30-70 parts of diol, 30-50 parts of toughening agent, 7-12 parts of defoamer, 7-12 parts of penetrant, and 3-7 parts of coupling agent. The invention uses water-based nano-inorganic silicone resin to compound nano-modified potassium silicate to provide a coating system with strong adhesion to inorganic substrates, and through the compounding of three penetrants, the penetration of the water-based coating system is further improved The performance of the invention improves the sand-fixing and sealing effect of the present invention, and can be directly used in the field of building decoration, which can be directly used for the concrete floor with sand and dust.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-permeability sand-fixing primer. Background technique [0002] Concrete is one of the most widely used and inexpensive building materials today. In my country's construction projects, more than 80% of buildings are made of concrete. At present, when concrete buildings are being renovated, the ground is usually leveled with cement mortar, which results in rough ground and is prone to cracks, sand and ash. Cut off and apply a sand-blocking primer to the smooth cut surface. If the existing sand-fixing primer is used directly on the rough ground, the sand-fixing effect is not good, and it is difficult to meet the construction requirements. [0003] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this ...
