Problems solved by technology

[0004] In the prior art, in order to prevent the epoxy resin from crystallizing when the temperature is below zero, more expensive modified epoxy resins are usually added or used, such as Wuxi resin 830 and Taiwan-produced 170 resin. These resins all belong to bisphenol F type epoxy resin, which greatly increases the production cost

Embodiment 1

[0023] Add 6kg of E-44 epoxy resin, 11kg of E-51 epoxy resin, and 4kg of butyl glycidyl ether into a mixing bucket, stir evenly, and then add the calculated amount of polyimide 1kg, barium sulfate in sequence under continuous stirring 58kg, heavy calcium powder 16kg, light calcium powder 4kg, stir evenly to obtain resin glue A; add polyamide epoxy curing agent 17kg, phenalkamine epoxy curing agent 1kg in another clean mixing bucket, stir evenly, and then add While stirring, add 1kg of 2, 4, 6-tris(dimethylaminomethyl)phenol, 1kg of polyimide, 60kg of barium sulfate, 16kg of heavy calcium powder, and 4kg of light calcium powder, and stir evenly to obtain curing agent B. When using dry-hanging glue to bond substances, mix the prepared resin glue A and curing agent B at a mass ratio of 1:1, apply it to the part to be bonded, and wait for it to dry.

Embodiment 2

[0025] Add 7kg of E-44 epoxy resin, 10kg of E-51 epoxy resin, and 5kg of polypropylene glycol diglycidyl ether into a mixing bucket, stir evenly, and then add the calculated amount of liquid silicone rubber 1kg, barium sulfate in sequence under continuous stirring. 60kg, heavy calcium powder 16kg, light calcium powder 5kg, stir evenly to obtain resin glue A; add polyamide epoxy curing agent 17kg, phenalkamine epoxy curing agent 1kg in another clean mixing bucket, stir evenly, and then add Add 1kg of tris(2-ethylhexanoic acid) salt of 2,4,6-tris(dimethylaminomethyl)phenol, 1kg of liquid silicone rubber, 60kg of barium sulfate, 16kg of heavy calcium powder and light calcium powder in a stirring state 4kg was stirred evenly to obtain curing agent B. When using dry hanging glue to bond substances, mix the prepared resin glue A and curing agent B at a mass ratio of 1:0.8, apply it on the part to be bonded, and wait for it to dry.

Embodiment 3

[0027] Add 5kg of E-44 epoxy resin, 8kg of E-51 epoxy resin, and 3kg of ethylene glycol diglycidyl ether into a mixing bucket, stir evenly and then add the calculated amount of carboxyl liquid nitrile rubber 1.5 kg, barium sulfate 60kg, heavy calcium powder 20kg, light calcium powder 2kg, stir evenly to get resin glue A; add polyamide epoxy curing agent 17kg, phenalkamine epoxy curing agent 1kg in another clean mixing bucket, stir Evenly, add 1kg of tris(2-ethylhexanoic acid) salt of 2,4,6-tris(dimethylaminomethyl)phenol, 1kg of carboxyl liquid nitrile rubber, 60kg of barium sulfate, heavy calcium Mix 16kg of powder and 4kg of light calcium powder evenly to obtain curing agent B. When using dry hanging glue to bond substances, mix the prepared resin glue A and curing agent B in a mass ratio of 1:1, apply it to the part to be bonded, and wait for it to dry.

Abstract

The invention relates to a low-temperature-resistant stone dry hanging adhesive and a preparation method thereof, and aims to provide a low-temperature-resistant low-production-cost stone dry hanging adhesive and a preparation method thereof. The low-temperature-resistant stone drying hanging adhesive comprises a resin adhesive A and a curing agent B, wherein the resin adhesive A is composed of E-44 epoxy resin, E-51 epoxy resin, diluter, toughener, barium sulfate, heavy calcium carbonate powder and light calcium carbonate powder. The preparation method comprises the following steps: uniformly stirring the E-44 epoxy resin, E-51 epoxy resin and diluter, sequentially adding the toughener, barium sulfate heavy calcium carbonate powder and light calcium carbonate powder, and stirring uniformly to obtain the resin adhesive A. The invention is low in raw material cost, and can resist low temperature without adding the high-cost bisphenol F-type epoxy resin; the resin adhesive A component can not crystallize even at -15 DEG C; and the prepared stone dry hanging adhesive has the advantages of high strength and low manufacturing cost.

Description

technical field [0001] The invention relates to a dry-hanging glue and a preparation method thereof, in particular to a stone dry-hanging glue and a preparation method thereof. Background technique [0002] "Dry hanging" generally refers to the construction method of using a steel skeleton for the stone base, and then connecting the steel skeleton with the stone with stainless steel pendants. The stainless steel pendant fixes the grooved parts at the bottom and upper part of the stone, and seals the joints with structural adhesive. The structural adhesive used is dry hanging adhesive. [0003] Dry hanging glue is usually composed of A and B groups, one group is mainly epoxy resin and filler, which is the main component of dry hanging glue; the other group is mainly curing agent and additive, which is the component of curing resin. When the two components are not in use, they are both liquid and will not solidify and crystallize. When in use, the two components are mixed and...
