Water-based wooden toy paint

Abstract

The invention relates to a water-based wooden toy paint, which is prepared by mixing and stirring the following raw materials in percentage by mass: 30 to 40 percent of waterborne acrylic emulsion, 15 to 25 percent of waterborne polyurethane dispersion, 3 to 5 percent of functional resin, 1 to 2 percent of film forming aid, 0.2 to 0.4 percent of wetting agent, 0 to 0.2 percent of leveling agent, 0.01 to 0.02 percent of preservative, 10 to 45 percent of pigment, 0 to 15 percent of water-based color paste, 0.5 to 1 percent of thickening agent and the balance of deionized water. The invention has the advantages that: the water-based wooden toy paint does not contain heavy metals and other toxic substances, meets the toy safety standard, cannot harm the health of children, and also has the characteristics of high drying speed, high film hardness, fullness, wear resistance, water resistance, after tackiness resistance and the like.

Description

Water-based wooden toy paint 【Technical field】 The invention belongs to the technical field of paint production, and in particular relates to a water-based wooden toy paint. 【Background technique】 China is the world's largest producer of toys. The toy industry occupies a certain position in my country's manufacturing industry and has a certain influence on the world's toy industry. my country is the largest toy manufacturing and exporting country in the world. 70% of the world's toys are manufactured in my country, but the qualified rate of toys in China's domestic market is only 76.3%. And it also faces severe problems such as intellectual property protection and EU trade barriers. For a long time, most of my country's export products have been based on the European and American markets with a low-price strategy. Domestic toys seldom use very environmentally friendly water-based paints, and more use solvent-based paints. Because the human body consumes too much heavy m...

Problems solved by technology

Water-based wood coatings have become a development trend due to their more environmentally friendly features, but there are still some shortcomings: one is that the drying of water-based wood coatings is particularly affected by climate, especially humidity, and the production efficiency is relatively low. Many manufacturers of water-based wooden furniture for children still use the original oil-based home paint equipment, and the production efficiency is low; the second is the performance of the product itself. Objectively speaking, after more than ten years of research and development and technical research, the comprehensive performance It has been greatly improved, and the performance of the paint film can basically meet the construction requirements and coating effect, but the physical properties of the paint film, such as hardness, fullness, heat resistance and water resistance, and high temperature back-stick resistance, are comparable to those of traditional oil-based polyurethane wood paints. There is still a certain gap than
