Problems solved by technology

[0002] In the construction process of architectural coatings, the quality of the primer plays a decisive role in the quality of the coating film. Problems such as blistering and cracking on the surface of the coating film are directly related to the base primer. There are many kinds of primers, but the permeability is very poor, the sealing performance is very poor, and it is easy to foam during construction

Abstract

The invention relates to a permeable epoxy seal primer. The permeable epoxy seal primer is characterized by being prepared from, by weight, 70-80 parts of 100% epoxy hard resin, 22-26 parts of thinner, 0.5-1.5 parts of adhesive force promoting resin, 40-60 parts of 75% epoxy resin, 4-8 parts of adhesive force promoter, 1-3 parts of permeation assistant, 1-3 parts of plasticizer and 30-50 parts of diluent. A corresponding amount of 100% epoxy hard resin is added to a reaction still according to the proportion, then thinner and adhesive force promoting resin are added, a preliminary mixture is obtained through stirring, the preliminary mixture and 75% epoxy resin are placed in a color modulation vat, diluent is added, permeation assistant, plasticizer and adhesive force promoter are added in sequence while stirring, and then the permeable epoxy seal primer is obtained. The permeable epoxy seal primer is high in permeability and sealing performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a permeable epoxy sealing primer. Background technique [0002] In the construction process of architectural coatings, the quality of the primer plays a decisive role in the quality of the coating film. Problems such as blistering and cracking on the surface of the coating film are directly related to the base primer. There are many kinds of primers, but their permeability is very poor, their sealing performance is very poor, and they are prone to foaming during construction. In order to meet the market demand, it is urgent to develop a high-permeability, high-sealing, high-adhesion sealing primer. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a permeable epoxy sealing primer with strong penetration and good sealing effect. [0004] The technical scheme adopted in the present invention: permeable epoxy seali...
