Problems solved by technology

At present, the performance analysis of commercially available marking pastes is carried out. One type is resin, which is greatly affected by temperature during use, and some types have a relatively strong odor. This type of marking paste has relatively low fluidity and can always maintain the shape and shape of the coating. Appearance; the other type is rubber, adding organic solvent products. This type of marking paste has relatively large fluidity, can be leveled soon after coating, and has a relatively small odor, but relatively large elasticity and relatively high strength.

Abstract

The invention relates to polysilazane-containing bolt anti-loosening marking paste and a preparation method thereof. The marking paste is prepared from the following raw materials: acrylate emulsion, a polysilazane solution, diethylene glycol monobutyl ether, white carbon black, orange pigment and silicone rubber. The preparation method comprises the following steps: mixing the acrylate emulsion with diethylene glycol monobutyl ether, sequentially adding other raw materials, fully and uniformly stirring, and standing until no bubble exists. After polysilazane is added, the use amount of filler in the marking paste can be effectively reduced, and meanwhile, an anti-sagging auxiliary can be replaced. The marking paste prepared by the method has excellent adhesion to metal, plastic and the like, is safe and non-corrosive to the surface of a metal material, is convenient to construct, has certain strength after being completely dried, and can achieve a certain anti-loosening effect.

Description

technical field [0001] The invention relates to the technology in the field of coatings, and more specifically, the invention relates to a preparation method of a polysilazane-containing bolt anti-loosening marking paste. Background technique [0002] Marking paste belongs to a kind of paint, which provides a convenient visual inspection method for nuts, bolts and other fastening and assembly parts to prevent loosening and / or tampering identification, and provides tamper-proof marking measures for fulfilling quality assurance responsibilities. If the assembly is tampered or loosened without permission Then the mark will be interrupted. It is easy to construct, quick-drying, has excellent adhesion to metal, and is safe and non-corrosive to the surface of metal materials. After the paste is completely dry, it has a certain strength, and the product uses fluorescent pigments, which are particularly clear under the irradiation of ultraviolet light. Convenient for inspection at ...
