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;

Abstract

The invention relates to a waterproof paint for architecture and building materials, especially to a water-base paint which is widely applied to brushing objects such as boarded floor, toy for children, corrugated paper, inner wall, outer wall, woodwork, damp proofing, cement, leak stopping, metal product, etc. The prescription of water-base paint totally differs from the traditional one, comprising: adding raw materials such as glycerin, xylitol, etc., except crylic acid emulsion, which are food-grade raw materials substantially, nontoxic and environmental-friendly absolutely. The water-base paint can be constructed directly, bring handsome looking and relieving labor strength of constructors. Furthermore, the water-base paint does not damage health of constructors, with multiple advantages of current waterproof paints.

Description

technical field [0001] The invention relates to waterproof coatings for buildings and building materials, especially a water-based paint, which can be widely used for painting wooden floors, children's toys, corrugated paper, interior walls, exterior walls, wood products, moisture-proof, cement, plugging, metal products etc. Background technique [0002] At present, the waterproof coatings on the market have solved the problem of high toxicity of coal tar in the past, and used petroleum asphalt, polyurethane, epoxy resin, acrylamide, formaldehyde, benzene and some additives, but the coatings made of these raw materials are volatile. Toxic gas directly endangers human health. Contents of the invention [0003] The object of the present invention is to provide a water-based paint, which has the characteristics of environmental protection, energy saving and non-combustibility. [0004] The object of the present invention is achieved by the following approach: the water-base...
