Adhesive for nylon mobile phone case and low-temperature silica gel as well as production method and application method of adhesive

Abstract

The invention discloses an adhesive for a nylon mobile phone case and low-temperature silica gel as well as a production method and an application method of the adhesive and relates to the technical field of adhesives. The production method of the adhesive comprises steps as follows: evenly dispersing 10-11% of a low-temperature silica gel base material, 85-90% of a diluent and 2% of a coupling agent by weight, and adding 1% of a curing agent before usage to obtain the adhesive. The production method of the adhesive is simple and easy to implement, the nylon case and the low-temperature silica gel can be well adhered to each other by the aid of the adhesive produced with the method, and the silica gel and the nylon case are ensured to have very high adhesive force and can pass related tests; during usage of the adhesive, the adhesive is sprayed on the nylon case firstly, the thickness is in a range of 10-11 mu m, the nylon case is left to stand at the normal temperature for 10-15 min and baked at the temperature of lower than 95 DEG C for 9-11 min, the case taken out is required to be molded with the low-temperature silica gel through oil pressure within the expiry date of the adhesive, and the process of adhesion of the nylon case and the low-temperature silica gel by the aid of the adhesive is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for nylon mobile phone casings and low-temperature silica gel and its production and application methods. Background technique [0002] The mobile phone casings of the prior art are generally made of plastic materials, but plastic materials generally have certain defects, such as PC materials are not wear-resistant, have a general texture and poor firmness; ABS materials have poor corrosion resistance and poor toughness; The PP material is easy to bend and deform, and cannot fit the mobile phone well; the TPU material is easy to be contaminated with dust and difficult to clean. [0003] In order to overcome the above problems, a mobile phone brand now proposes to combine low-temperature silica gel on the nylon case to obtain a mobile phone case, but nylon and low-temperature silica gel are very difficult to attach, and this problem has become an urgent problem for ...
