Reactive polyurethane adhesive for mobile phone circuit board assembly protection

Abstract

The invention discloses reactive polyurethane adhesive for mobile phone circuit board assembly protection. The reactive polyurethane adhesive for the mobile phone circuit board assembly protection comprises a shell; a threaded spiral groove is formed in the upper end of the shell; the inner wall of the threaded spiral groove is in threaded connection with a connector; the upper end of the connector is fixedly connected with a flat-mouth cover; a circular through hole is formed in the upper end of the flat-mouth cover; the flat-mouth cover is connected with an anti-sticking sleeve in a sleevingmanner; a rectangular groove in the right end of the shell is connected with a cover in a clamping manner; a hairbrush is placed in the rectangular groove; the hairbrush comprises a hairbrush stick;the upper end of the hairbrush stick is fixedly connected with a fixed seat; bristles are fixed to the upper end of the fixed seat; and an annular clamping block is mounted at the upper end of the fixed seat. According to the reactive polyurethane adhesive for the mobile phone circuit board assembly protection, the problems that the reactive polyurethane adhesive cannot be smeared uniformly to affect a mobile phone circuit board assembly protection effect to a certain extent, the function is single, the practicability is poor and the commercial value is not high are solved.

Description

technical field [0001] The invention relates to the technical field of polyurethane adhesives, in particular to a reactive polyurethane adhesive used for assembly and protection of mobile phone circuit boards. Background technique [0002] Polyurethane is polyurethane. The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. , plastic and nylon, etc., used in airports, hotels, building materials, coal mines and cement plants, etc. The adhesive has good adhesion to metal, glass, ceramics, leather and fibers, etc., and can be used to make reactive polyurethane adhesives , need to be used in the assembly of mobile phone circuit board, mainly play a protective effect. [0003] But the existing technology also has the following deficiencies: [0004] 1. When bonding with reactive polyurethane adhesive, it cannot be applied evenly, which will affect the protection effect of mobile...
