Microcapsule coating material for thread-off proof screws

Abstract

Relating to the technical field of coating processing and production, the invention discloses a microcapsule coating material for thread-off proof screws. The coating material is composed of the following raw materials by weight: 40-50 parts of epoxy resin, 10-16 parts of a curing agent, 15-21 parts of microcapsule filler, 20-30 parts of pigment, 12-18 parts of polybutylene terephthalate and 22-28parts of a graphene / Ti-based composite material. The preparation method includes: putting epoxy resin, polybutylene terephthalate and the graphene / Ti-based composite material into a high-temperaturestirrer, and performing heating at 200DEG C for 20min to prepare a solution; adding the microcapsule filler into the prepared solution, and placing the solution in a 8MPa high-pressure container for 2h; and then taking out the solution, adding the pigment into the solution, performing stirring for 10min, adding the curing agent, and conducting stirring to a sticky state, and performing standing for 8h to form the microcapsule coating material for thread-off proof screws. The microcapsule coating material provided by the invention has good adhesive force up to grade 1, and endows screws with better thread-off proof performance.

Description

technical field [0001] The invention relates to the technical field of coating processing and production, in particular to a microcapsule coating material for anti-loosening screws. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. [0003] Screw is a general term for fasteners, a daily colloquial language. Screws are an indispensable industrial necessity in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws used in TVs, electrical products, musical instruments, furniture, etc.; large screws used in engineering, construction, and bridges , nuts; transportation equipment, airplanes, trams, automobiles, ...
