Embodiment 1

[0018] The self-made glue provided in this embodiment 1 is composed of granular injection molding raw materials and methyl ethyl ketone, wherein the mass fraction of granular injection molding raw materials is 10%, the mass fraction of methyl ethyl ketone is 90%, and the granular Granular injection molding raw materials and methyl ethyl ketone are mixed according to their respective mass fractions, and the final mixture of granular injection molding raw materials and methyl ethyl ketone is in a fluid state.

[0019] The granular injection molding raw material in Embodiment 1 includes any one of acrylonitrile-butadiene-styrene copolymer, polycarbonate, polypropylene and polyvinyl chloride, that is, the composition of granular injection molding is single, and it cannot be the above-mentioned several a mixture of materials.

[0020] In addition, it should be noted that the self-made glue made by mixing polycarbonate and methyl ethyl ketone can only bond polycarbonate products. T...

Embodiment 2

[0026] The self-made glue provided in the second embodiment includes: granular injection molding raw materials and methyl ethyl ketone, wherein the mass fraction of granular injection molding raw materials is 13%, the mass fraction of methyl ethyl ketone is 87%, and the granular Granular injection molding raw materials and methyl ethyl ketone are mixed according to their respective mass fractions, and the final mixture of granular injection molding raw materials and methyl ethyl ketone is in a fluid state.

Embodiment 3

[0028] The self-made glue provided in the second embodiment includes: granular injection molding raw materials and methyl ethyl ketone, wherein the mass fraction of granular injection molding raw materials is 16%, the mass fraction of methyl ethyl ketone is 84%, and the granular Granular injection molding raw materials and methyl ethyl ketone are mixed according to their respective mass fractions, and the final mixture of granular injection molding raw materials and methyl ethyl ketone is in a fluid state.

Abstract

The invention provides self-prepared glue and a preparation method thereof. The method comprises the following steps of adding a granular injection molding raw material and methyl ethyl ketone into a stirring container according to respective preset mass fractions; stirring methyl ethyl ketone and the granular injection molding raw material by overturning the stirring container, and besides diluting the granular injection molding raw material with the methyl ethyl ketone until the granular injection molding raw material is diluted to be fluid with methyl ethyl ketone. When the self-prepared glue prepared in the invention is used for bonding products, the phenomenon of whitening cannot be generated.

Description

technical field [0001] The invention relates to the technical field of glue, more specifically, to a self-made glue and a preparation method thereof. Background technique [0002] At present, in the manufacturing process of electronic products, the bonding process is often used for plastic products, and the two parts are bonded together by various types of glue. For example, the front shell and the rear shell of the earphone are formed by bonding process Headphone case. However, the existing glues have the following technical problems when bonding different parts of plastic products: [0003] After the glue solidifies, there will be whitening phenomenon, which will seriously affect the appearance of finished electronic products and reduce the user's perception of electronic products. Contents of the invention [0004] In view of the above problems, the purpose of this invention is to provide a kind of self-made glue and its preparation method, to solve the problem that t...
