Abstract
The invention discloses a multifunctional epoxy primer and a preparation method for the same. The multifunctional epoxy primer is composed of the ingredients in parts by weight: 50 parts of epoxy resin, 1.5 parts of bentonite, 10 parts of dimethylbenzene, 3 parts of n-butyl alcohol, 20 parts of titanium dioxide, 14.5 parts of barium sulphate, and 1 part of auxiliaries. The preparation method comprises the following steps of weighing the materials, pre-mixing, grinding and dispersing, adjusting the viscosity and colour, filtering, packaging and warehousing. The multifunctional epoxy primer prepared by the method aforementioned has the following main technical indexes that with respect to drying time, a surface drying time is not greater than 2 hours, and a hard drying time is not greater than 24 hours; acid resistance is not less than 48 hours; alkali resistance is not less than 48 hours; salt fog resistance is not less than 200 hours; and an adhesive force is not greater than 1 level. The preparation method disclosed by the invention is simple, convenient, and easy to realize; and the prepared multifunctional epoxy primer is great in an adhesive force on steel structures and concrete base surfaces, in particular, on base materials such as stainless steel, galvanized parts and aluminium alloys so as to increase the adhesive force on the base materials, and is capable of remarkably increasing an adhesive force on paint, thus prolonging the service lives of the base materials.
