Embodiment 1

[0119] Acrylic resin-1, 1,4-butanediol dimethacrylate, sodium p-toluenesulfonate, dimethyl-p-toluidine, titanium dioxide color paste, coupling agent KH-570 of the weight parts listed in Table 1 Mix and store as component A, get the benzoyl peroxide and dibutyl phthalate listed in Table 1 and mix and store as component B, when using, mix the first component with the Mix component B evenly, take a small amount and spread it on the lap joint of the two boards, measure the shear strength for 24 hours after curing and polishing, put the rest in a 200ml paper cup, and get the product P1 after curing.

[0120] The obtained product P1 was tested according to the test method for its anti-yellowing performance, curing time, and 24-hour shear strength, and the results are listed in Table 1.

Embodiment 2

[0122] Acrylic resin-2, 1,4-butanediol dimethacrylate, copper dichloride, 600 mesh kaolin, 1500 mesh aluminum hydroxide, 80nm modified kaolin, p-toluenesulfonate in parts by weight listed in Table 1 Sodium peroxide, dimethyl p-toluidine, titanium dioxide color paste, coupling agent KH-570 are mixed and stored as component A, and benzoyl peroxide and dibutyl phthalate listed in table 1 are taken Mix and store as B component, get the dodecylmercaptan listed in Table 1 and store as C component, during application, combine described A component, described B component and described C component Divide and stir evenly, take a small amount and apply it on the lap joint of the two boards, measure the shear strength for 24 hours after curing and polishing, and put the rest in a 200ml paper cup, and obtain the product P2 after curing.

[0123] The resulting product P2 was tested according to the test method for its anti-yellowing performance, curing time, and 24-hour shear strength, and ...

Embodiment 3

[0125] Acrylic resin-3, 1,6-hexanediol dimethacrylate, p-tert-butylcatechol, dimethyl-p-toluidine, titanium dioxide color paste, coupling agent KH- 570 and 600 mesh kaolin, 1500 mesh aluminum hydroxide, 80nm modified kaolin, and sodium p-toluenesulfonate are mixed and stored as component A, and benzoyl peroxide and phthalic acid dicarboxylate listed in Table 1 are taken. The butyl ester is mixed and stored as the B component, and the dodecyl mercaptan listed in Table 1 is stored as the C component. When applying, stir the A component, the B component and the C component evenly, take a small amount and apply it on the lap joint of the two boards, measure the shear strength for 24 hours after curing and polishing, and put the rest in a 200ml paper cup Among them, the product P3 is obtained after curing.

[0126] The resulting product P3 was tested for its anti-yellowing performance, curing time, and 24-hour shear strength according to the test method, and the results are listed...

Abstract

The invention discloses a normal-temperature bi-component or multi-component curing system and an application thereof. The normal-temperature bi-component or multi-component curing system comprises the following components in parts by weight: (A) 10-90 parts of acrylic-based resin, (B) 0-30 parts of acrylic ester with the degree of functionality more than or equal to 2, (C) 0-2 parts of polymerization inhibitors, (D) 0-85 parts of fillers, (E) 0.005-10 parts of organic acid and / or organic acid salt, (F) 0-4 parts of sulfur alcohol, (G) 0.05-3 parts of tertiary amine, (H) 0-10 parts of addition agents, (I) 0.1-6 parts of curing agents and (J) 1-15 parts of dispersing agents. The normal-temperature bi-component or multi-component curing system disclosed by the invention is good in yellowing resistance, high in curing velocity and short in curing time and can be conveniently used at the normal temperature or even in winter.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a two-component or multi-component curing system at room temperature and its application. Background technique [0002] The hardness, rigidity, toughness and weight of the artificial solid surface material are between natural stone and wood, with appropriate strength and impact strength, and secondly, it has chemical corrosion resistance and low water absorption, which is convenient for design, processing, transportation, installation and renovation , Repair, etc., especially the processing of various products can be integrated. The colors are gorgeous and dazzling, which can meet the needs of different users and designs, and avoid the phenomenon of single color and uneven color of natural materials. Applications of solid surfaces can be infinitely extended and combined. Therefore, in the current decoration market, artificial solid surface materials occupy an increasing share. No...
