Embodiment 1
[0014] (1) Firstly, self-made wollastonite powder, mixed silica powder and calcium carbonate powder in a molar ratio of 1:1, calcined at 1050°C for 110 minutes, and then ground. Then, weigh 1,000 grams of bisphenol A epoxy resin with an epoxy value of 0.52mol / 100g, 200 grams of triethylenetetramine, 200 grams of carboxyl-terminated liquid cyanide rubber, 2,4,6-tris(dimethyl 1.0 g of aminomethyl)phenol, 35 g of aminopropyltriethoxysilane (KH-550), 300 g of silica lime powder, 20 g of fumed silica with a particle size of 15-20 nm. Mix the above components at a room temperature of 35°C to obtain a room temperature curing adhesive for porcelain sleeve bonding. The adhesive is ready to use when it is prepared, and it is best to use it up in 30 to 45 minutes under natural conditions. If gelation occurs, stop using it.
[0015] (2) Grind and level the joints of the upper and lower porcelain sleeves, clean the oil, dust and other impurities at the joints and heat and dry them. After cooli...

[0018] (1) Firstly, self-made wollastonite powder, mixed silica powder and calcium carbonate powder in a molar ratio of 1:1, calcined at 1070°C for 90 minutes, and then ground. Then, weigh 1,000 grams of bisphenol A epoxy resin with an epoxy value of 0.51mol / 100g, 250 grams of triethylenetetramine, 225 grams of carboxyl-terminated liquid cyanide rubber, 2,4,6-tris(dimethyl 1.2 grams of aminomethyl)phenol, 40 grams of aminopropyltriethoxysilane (KH-550), 400 grams of silica lime powder, 15 grams of fumed silica with a particle size of 15-20 nm. Mix the above components at a room temperature of 28°C to obtain a room temperature curing adhesive for porcelain sleeve bonding. The adhesive is ready to use when it is prepared, and it is best to use it up in 30 to 45 minutes under natural conditions. If gelation occurs, stop using it.

Embodiment 3
[0022] (1) First, self-made wollastonite powder, mixed silica powder and calcium carbonate powder in a molar ratio of 1:1, calcined at 1060°C for 100 minutes, and then grind. Then, weigh 1000 grams of bisphenol A epoxy resin with epoxy value of 0.52mol / 100g, 300 grams of triethylenetetramine, 250 grams of carboxyl-terminated liquid cyanide rubber, 2,4,6-tris(dimethyl 1.0 g of aminomethyl)phenol, 50 g of aminopropyltriethoxysilane (KH-550), 500 g of silica lime powder, 10 g of fumed silica with a particle size of 15-20 nm. Mix the above components at room temperature 15°C to obtain room temperature curing adhesive for porcelain sleeve bonding. The adhesive is ready to use when it is prepared, and it is best to use it up in 30 to 45 minutes under natural conditions. If gelation occurs, stop using it.
[0023] (2) Grind and level the joints of the upper and lower porcelain sleeves, clean the oil, dust and other impurities at the joints and heat and dry them. After cooling, scrub the ...
