Abstract

The invention relates to a surface coating material of a high rigidity steel tape belt. The coating material comprises an undercoat coating material and a top coat coating material. Wherein the undercoat coating material comprises the following components in percentage by weight: 29-30% of pigment, 25-29% of polyester resin, 1-5% of melamine resin, 1-3% of epoxy resin and 35-39% of solvent; and the top coat coating material comprises the following components in percentage by weight: 12-21% of melamine resin, 17-21% of polyester resin, 4-6% of aggregate, 50-57% of solvent and 5-7% of antifoaming agent. The surface coating material of the high rigidity steel tape belt has the beneficial effects that the strength of coating is superior to that of the other coatings, and the coating material has good hardness and toughness; with regard to the close distance measurement of the tape, the coating material can extend the extension length and bending resistance of the tape to the maximum extent; and at the same time, the coating material meets an environment-friendly requirement, and is nontoxic and harmless.

Description

Technical field [0001] The invention relates to a steel tape measure tape, in particular to a coating material for the steel tape measure tape. Background technique [0002] The surface coating of the tape is generally composed of primer coating and top coating. [0003] The surface coating material of the existing tape measure is relatively thin and the coating is not dense enough, which causes the tape to be easily bent during actual use and has poor erection performance, which affects the measuring length of the tape measure at close distances. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a high-rigidity steel tape measure tape surface coating material, which aims to solve the above-mentioned problems. [0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: [0006] The invention consists of primer painting and top paint painting; [0007] T...
