Problems solved by technology

[0008] ③The solid content of benzyl alcohol, nonylphenol, dodecylphenol, acetone, toluene, and xylene is diluted, the volatility is greater, the shrinkage rate is greater, and it is easy to cause shedding problems after a long time!
[0009] ④Current beautician curing agent part basically contains 30% to 50% benzyl alcohol, nonylphenol, dodecylphenol, these are added as fillers to greatly reduce the bonding performance of beautifying agent, is the beautifying agent One of the important reasons why the agent is easy to fall off after curing
[0010] ⑤The curing agent part contains a large amount of benzyl alcohol, nonylphenol, and dodecylphenol, which makes the mechanical strength of the cured product insufficient, poor wear resistance, and low viscosity, which is also one of the reasons for easy falling off
[0011] This formula is a 2:1 beautifying agent formula, which has the problem of high brittleness, which does not meet the needs of beautifying seam construction and thermal expansion and contraction of tiles. Therefore, it is necessary to do toughness treatment on curing, so that the cured product can be both soft and hard

Embodiment 1

[0032] The preparation method of a transparent paste beautifying agent curing agent disclosed by the present invention, the specific preparation method is as follows:

[0033] Add 10-40 parts of 1.3 cyclohexanedimethylamine curing agent into the reaction kettle, stir the reaction kettle slowly, and at the same time add 5-20 parts of T5000 polyetheramine, 5-20 parts of D2000 polyetheramine, 5-20 parts of D400 polyether amine, disperse and stir the reactor, then slowly add 5-20 parts of 4080E hydrogenated epoxy resin and continue stirring, then add 5-30 parts of electronic grade 128 epoxy resin, and slowly add 5-20 parts of carbon 12-14 alkyl glycidyl ether, after the dropwise addition, stir and disperse at a speed of 400-700 rpm for 1-3 hours, then stand still for 8-12 hours, add 1-3‰ of UV absorbers, 1-3‰ of Light stabilizer, add 3-5% fumed silicon dioxide sio2, disperse for 8-15 minutes at a speed of 1000-1300 rpm, raise the temperature to 45-55 degrees, add 6-8‰ flow-stoppin...

Embodiment 2

[0035] Curing agent components: Add 30 parts of 1.3 cyclohexyl dimethylamine curing agent to the reaction kettle, and slowly stir the reaction kettle at a speed of 200 rpm. At the same time, add 10 parts of T5000 polyetheramine, 10 parts of D2000 polyetheramine, 20 parts of D400 Polyether amine, the reaction kettle is slowly dispersed and stirred at a speed of 300 rpm, then slowly add 10 parts of 4080E hydrogenated epoxy resin and continue to stir, then add 10 parts of electronic grade 128 epoxy resin, and slowly add 10 parts of carbon 12-14 alkyl Glycidyl ether, after the dropwise addition is completed, stir and disperse at a speed of 600 rpm for 2 hours, then stand still for 10 hours, add 2‰ of ultraviolet absorbers, 2‰ of light stabilizers, and add 5% of fumed silicon dioxide sio2, Disperse at a speed of 1200 rpm for 10 minutes, raise the temperature to 50 degrees, add 8‰ flow-stopping agent, disperse for another 10 minutes, and vacuumize for 15 minutes to obtain a 2:1 trans...

Abstract

The invention relates to a transparent paste beautification sealer curing agent for tiles and a preparation method thereof. A component B of the curing agent adopts a cycloamine curing agent 1.3bis(aminomethyl)cyclohexane for modification reaction to reduce the number of contained active bonds and lower the reaction activity of the curing agent, thus reaching the effects of controlling the curingspeed and eliminating a matte surface on the surface of a cured product. Epoxy resin is used as a chain extender of the curing agent to improve the compatibility between the curing agent and resin, and at the same time, D400 polyetheramine, D2000 polyetheramine and T5000 polyetheramine are mixed with epoxy resin for modification under certain operation conditions, thus obtaining a raw material ofbeautification sealer curing agent for tiles with moderate viscosity, good weather resistance, good water resistance, fast curing speed, high glossiness and moderate rigidity and softness.

Description

technical field [0001] The invention relates to the field of epoxy resin, in particular to a preparation method of a 2:1 transparent paste epoxy beautifying agent curing agent. Background technique [0002] Epoxy resin is a widely used basic resin, and it is combined with curing agents with different properties to produce cured products with different properties. Epoxy beauty joint agent is an indispensable tile decoration product in the current decoration. It can endow the tile gap with rich colors, smooth as porcelain, no mildew, easy to change color, and no dirt. It also gives practical and aesthetic functions. Ceramic tiles bring the decorative effect of icing on the cake, making the overall decoration more exquisite and beautiful, magnificent or euphemistic and elegant. The commonly used matrix of beauty joint agent is epoxy resin, which is mixed with curing agent and then added with pearl powder to obtain solid beauty joint agent of various colors and styles. A comple...
