Primer applicable to security door and preparation method of primer

Abstract

The invention relates to a primer applicable to a security door and a preparation method of the primer. The primer is prepared from the following raw materials in percentage by weight: base stocks: 30%-50% of aqueous epoxy ester resin and 6%-10% of amino resin; aids: 3%-5% of a cosolvent, 1%-3% of a neutralizer, 10%-15% of deionized water, 0.5%-2% of a wetting dispersant, 0.1%-0.5% of a defoaming agent and 0.1%-0.3% of a base material wetting agent; pigments and fillers: 15%-25% of a red pigment free of heavy metal, 5%-10% of compound zinc phosphate, 5%-10% of compound ferrotitanium powder and 1%-5% of nanoscale precipitated barium sulphate. According to the preparation method, an aqueous coating is used as a solvent, so that the fire risk during construction is eliminated, the atmospheric pollution is alleviated, and the working environment condition is improved; a coating process of existing security doors is not changed, the workability of the product is relatively good, and the aqueous coating can be used for direct coating construction in humid environment on a wet surface and is well adaptive to the surface of the material; a coating tool can be washed by water, so that the consumption of a cleaning solvent is greatly reduced.

Description

technical field [0001] The invention relates to the field of plastic paints, in particular to a primer suitable for anti-theft doors and a manufacturing method thereof. Background technique [0002] With the increasing shortage of natural resources and people's increasing demand for resources, many areas where steel and wood are used are replaced by recyclable plastics. Therefore, the application of plastics in today's society is becoming more and more extensive, and the protection and decoration of plastic surfaces are becoming more and more important. Due to the low surface energy of plastics, there are certain difficulties in the adhesion of paints on the surface, so most of the paints used on plastic surfaces are solvent-based paints. A large proportion of solvent-based coatings are volatile solvents, which will volatilize into the atmosphere after coating, causing a great degree of air pollution. These organic solvents are mainly derived from petroleum, which is also a...
