Abstract

The invention relates to transparent high-hardness yellowing-resistant epoxy stone face glue and a preparation process thereof. The transparent high-hardness yellowing-resistant epoxy stone face glueis characterized by being prepared from glue A and glue B, wherein the glue A is prepared from epoxy resin 128, epoxy resin 127, epoxy resin 170, phenylcarbinol, an epoxy active diluent 622, an organic silane coupling agent 550, an anti-foaming agent 6020, a leveling agent BYK-306 and an anti-ultraviolet agent L-9522; the glue B is a modified amine curing agent; the glue A and the glue B are uniformly mixed according to the mass ratio of (2 to 4):1; de-foaming is performed in vacuum; then, the glue is scraped onto a stone panel; curing is firstly performed for 30min at the room temperature; then, curing is continuously performed at 60 DEG C for 1h; next, the material is taken out; after the cooling, the shore hardness of an obtained cured object is 88 or higher; the grinding performance isgood; the adhesion force reaches grade 1; the yellowing resistant performance is good; no obvious yellowing occurs after the sunlight irradiation for 1 year; the glue A does not crystallize. The rawmaterials in a formula can be easily obtained; the cost is low; the performance is excellent; the face glue is suitable for large-scale popularized use.

Description

technical field [0001] The invention relates to a formula of stone surface glue. In particular, it relates to a transparent, high-hardness, anti-yellowing epoxy stone surface glue and a preparation process thereof. Background technique [0002] Due to the increase of environmental protection supervision, upstream enterprises have stopped or reduced production, resulting in insufficient supply of 1,3-BAC, the core raw material of epoxy stone surface adhesive, which limits the production capacity of transparent, high hardness, and yellowing-resistant epoxy stone surface adhesive. Meet the needs of the market. Contents of the invention [0003] The purpose of the present invention is to provide a transparent, high-hardness, anti-yellowing epoxy stone surface glue preparation process to solve the technical problems of insufficient supply of existing raw materials, high price, and difficult procurement. [0004] In order to solve the above-mentioned technical problems, the te...
