[0019] The preparation process used is as follows:

[0020] a. Add 100 parts by weight of the filler to the stirring tank at a set temperature of 80°C, fully stir and raise the material temperature to 60-65°C;

[0021] b. Spray 1-10 parts by weight of silane coupling agent uniformly in the filler, fully stir and cool to room temperature;

[0022] c. The organic bentonite and fumed silica are mixed at a weight ratio of 4-8:1 and then added with an organic solvent 2-3 times the weight of the mixture to fully disperse and then stand to obtain a pre-activated product;

[0023] d. Adding the homing coupling agent modified filler obtained in step b to the unsaturated polyester resin, heating and stirring, and adding 1.0-3.0% of the total weight of the unsaturated polyester resin as a percentage by weight at 60-70°C c The obtained pre-activated product;

[0024] e. Cool to a paste, and pack into finished products.

preparation Embodiment 1

[0026] 100 parts by weight of 988-3 resin is 100 parts by weight of the filler modified by the silane coupling agent and 1 part by weight of the pre-activated material, wherein the content of the silane coupling agent is 1% of the filler.

preparation Embodiment 2

[0028] 100 parts by weight of 988-3 resin is 120 parts by weight of filler modified with silane coupling agent and 1.5 parts by weight of pre-activated material, wherein the content of silane coupling agent is 2% of the filler.

Abstract

The invention provides a marble adhesive, which comprises the following components: an unsaturated polyester resin, a modified filler and a pre-activated material, wherein the filler is a silane coupling agent-modified filler. The preparation process of the marble adhesive is simple and can greatly improve the adhesive strength and construction range of the marble adhesive, obviously improve the continuous reliability of materials adhered by the marble adhesive and lower possibility of hydrolysis and powdering. The oil absorption of the marble adhesive provided by the invention is reduced greatly, and by increasing the filled amount of the filler in the resin, the performance to price ratio of the product can be improved greatly.

Description

Technical field: [0001] The invention relates to an adhesive for construction, in particular to a silane coupling agent modified marble glue. The invention also relates to its preparation process. Background technique: [0002] Marble glue is the main product in the field of stone chemical industry. The existing marble glue is generally composed of unsaturated multi-element polyester, fillers and a small amount of thixotropic agent hydrogenated castor oil. It is used to bond marble, Granite and stone. However, the filler used in marble glue has high oil absorption value and poor wettability, resulting in low bonding strength, easy pulverization and cracking, and poor water resistance; hydrogenated castor oil thixotropy is greatly affected by environmental temperature and seasons, and it is too thin and easy to flow in summer Hanging and easy to settle, it is too hard to mix in winter. Summary of the invention: [0003] The technical problem to be solved by the present invention ...
