High-performance environment-friendly water-based single-component primer for plastic base materials and production process of primer

Abstract

The invention relates to a high-performance environment-friendly water-based single-component primer for plastic base materials and a production process of the primer. The primer consists of the following components in parts by weight: 50-65 parts of a water-based single-component acrylic emulsion, 10-15 parts of deionized water, 5-10 parts of a water-based film-forming assistant, 10-15 parts of water-based cellulose, 5-10 parts of water-based wax liquor and 0.1-0.3 part of a water-based defoaming agent. The primer has the beneficial effects that the silver discharge performance is good, the large-molecular-weight water-based acrylic emulsion is adopted, the advantage of good directionality is adopted, and the cellulose is combined, so that silver discharge is improved. Drying is fast, a conventional mode of "twice coating and twice baking" is converted into a mode of "twice coating and once baking", and the effect of high fullness and high metal feeling after coating can be guaranteed. The adhesive force is high, and the water-based acrylic emulsion containing trace hydroxyl is beneficial for combination with hydrogen bonds on materials; and meanwhile, an adhesive force promoter is added, so that the adhesion force of the primer to the material and the interlayer is improved.

Description

technical field [0001] The invention belongs to the field of water-based paints, in particular to a high-performance, environment-friendly water-based one-component primer for plastic substrates and a production process. Background technique [0002] The successive implementation of the "Environmental Protection Law" and the "Air Pollution Prevention and Control Law" has forced enterprises to strictly abide by the amount of VOC emissions and reduce the degree of pollution to the environment. The original water-based single-pack primer has deficiencies such as silver displacement, slow drying, and poor adhesion. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a high-performance environmental protection water-based one-component primer and production process for plastic substrates. [0004] The purpose of the present invention is accomplished through the following technical solutions. The...
