Embodiment 1

[0018] A polymer cement waterproof coating with good adhesion is made of the following components in mass percentage: 60% of pure acrylic emulsion, 5% of modified polymer powder, 0.5% of rare earth light-changing agent, 0.5% of defoamer, Polyether polyol 4%, polyurethane thickener 6%, preservative 0.2%, hydroxyethyl cellulose 1%, sodium dodecylsulfonate 0.8%, propylene benzene emulsion 3%, dispersant 0.4%, balance is deionized water;

[0019] The above-mentioned modified polymer powder is made of the following components by mass percentage: 80% of nano-silicon dioxide, 5% of nano-silicon carbide, 5% of kaolin powder, 5% of nano-boron carbide, and 5% of fly ash; the preparation method as follows:

[0020] 1) Bake nano-silica, nano-silicon carbide, kaolin powder, nano-boron carbide and fly ash in a baking equipment at a temperature of 86-95°C for 30-40 minutes, then quickly cool to room temperature, and pulverize through 60 mesh Sieve, get the mixed powder for later use;

Abstract

The invention relates to polymer cement waterproof paint having good adhesion performance. The polymer cement waterproof paint having good adhesion performance comprises the following raw materials by mass percentage: 60% of a pure acrylic emulsion, 5% of modified polymer powder, 0.5% of a rare earth light conversion agent, 0.5% of an antifoaming agent, 4% of polyether polyol, 6% of a polyurethane thickening agent, 0.2% of an antiseptic, 1% of hydroxyethyl cellulose, 0.8% of sodium dodecanesulphonate, 3% of a phenylpropane emulsion, 0.4% of a dispersant, and the balance of deionized water. The prepared high built crack-resistant polymer cement waterproof paint has the advantages of large elongation percentage, high bonding strength, good water resistance, good alkali resistance and good weatherability, can be directly applied on bases without obvious water, and can be widely applied for watertightness of the bases with small activity such as kitchen, toilet, balcony and basement.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a polymer cement waterproof coating with good adhesion. Background technique [0002] At present, the bonding interface of some building components used in the construction field at home and abroad often has surface cracking, falling off, and even damage to the component body due to the influence of various factors, resulting in doubled building safety hazards. The specific manifestations are as follows: 1. In the external wall thermal insulation project and its decoration project, the pasted thermal insulation board and decorative board (brick) often appear to fall off from the external wall of the building; 2. The wall cement plastering of the building envelope Surface cracking, hollowing, and cracking will occur in the layer, thermal insulation leveling layer, finishing layer, roof concrete waterproof layer, etc.; , caulking materials, caulking materials, potting materials, ...
