Embodiment 1
[0026] Water-based paint for wood flooring, the ratio of its components by weight is: 15 parts of silicon acrylic emulsion, 10 parts of pure acrylic emulsion, 10 parts of glycerin, 25 parts of xylitol, 1 part of sodium pyrophosphate, 40 parts of water share.
[0027] The silicone-acrylic emulsion used is based on pure acrylic emulsion, which is grafted by adding imported silicone monomers during the polymerization process. Due to the special function of silicon monomers, this product has strong adhesion, high gloss, and anti-corrosion properties. Ultraviolet rays, impact resistance, pollution resistance, high hardness and other characteristics, high cost. The chemical characteristics of the emulsion are: solid content: 50%±2, viscosity: 200cP-1000cP, pH value: 7.5-9.0, Tg value: 15°C.
[0028] Pure acrylic emulsion is mainly made of methacrylic acid ester and acrylic resin, and is polymerized with imported high-efficiency emulsifier and functional monomer. Strong force, good...
Embodiment 2
[0030] Water-based paint for corrugated paper, the ratio of each component is: 5 parts of pure acrylic emulsion, 20 parts of styrene-acrylic emulsion, 5 parts of glycerin, 20 parts of xylitol, 1 part of sodium pyrophosphate, 50 parts of water .
[0031] The styrene-acrylic emulsion used herein has excellent water resistance and outstanding calcium ion stability, which is beneficial to the long-term storage of the finished paint and has low cost. The chemical characteristics of the emulsion are: solid content: 47%±1, viscosity: 500cP-2000cP, pH value: 7.5-9.0, Tg value: 10°C.
[0032] The preparation process of the water-based paint is as follows: at room temperature above 5°C, in a clean and dust-free environment
[0033] Step 1: Pour water into the container, pour in xylitol and stir until it is completely dissolved, then pour in glycerin and mix well, then pour in sodium pyrophosphate and stir until it is completely dissolved, and the obtained solution is ready for use;
