Problems solved by technology

The resin used in the prior art, a class is unsaturated polyester resin, and this resin curing speed is faster, and intensity is higher, but anti-yellowing, aging resistance are poor, and environmental pollution is heavier; A class is epoxy resin , this kind of resin has high strength and good aging resistance, but the curing speed is slow. It often takes 2-3 days to enter the grinding and polishing process when using the drying board process, which affects production efficiency. When using assembly line production, it needs to be heated to accelerate curing. Escape affects the environment and increases energy consumption, so it is necessary to improve

Embodiment 1

[0033] In a 500ml three-neck glass flask with stirring and reflux condenser, add 188g of epoxy resin E-54 and 75g of vinyl cyclohexene diepoxide ERL-4205, turn on the stirrer, fill with nitrogen, and raise the temperature to 90°C. Put 129.6g of acrylic acid dissolved with 0.5g of triphenylphosphine and 1.0g of p-methoxyphenol into the feeding bottle, drop evenly into the flask, control the temperature at 90-95°C, drop it in 1.5 hours, raise the temperature to 115°C, and 115°C-118°C constant temperature reaction for 4 hours, the steam in the bottle is refluxed through the condenser to continue the reaction. From the beginning of adding acrylic acid, take the material every hour to measure the acid value. After the reaction, the product in the cooling bottle was cooled, and when the temperature dropped to 40° C., it was discharged and nitrogen filling was stopped to obtain 392 g of product. The viscosity, hue and acid value of the product epoxy acrylate resin were analyzed by sa...

Embodiment 2

[0037]When preparing epoxy acrylate resin, the raw materials used are bisphenol F type epoxy resin YDF-175, epoxy equivalent 170, viscosity 2200mpa.s at 25°C, 170g, vinyl ring ethylene diepoxide ERL-4205 75g , catalyst triethylamine 1.0g, polymerization inhibitor ST-1 0.8g acrylic acid 129.6g, operating conditions are the same as embodiment 1, obtain epoxy acrylate resin 372.5g, sampling analysis results are shown in Table 1.

[0038] In the preparation of photocurable resin composition, used raw material is:

[0039] Prepared epoxy acrylate resin 140g, polyester acrylate GF-3106 20g, reactive diluent tert-amyl alcohol triacrylate 24g, acrylate isodecyl 11g, plasticizer polyether 10g, photoinitiator bis 2,6 - 0.8 g of difluoro-3-pyrrole phenyl titanocene (GR-FMT, 784), no filler was added, and the rest was the same as in Example 2 to obtain 204 g of a photocurable resin composition.

[0040] The composition and its sample after 20 minutes of sunlight irradiation, the test re...

Embodiment 3

[0042] When preparing epoxy acrylate resin, the raw materials used are bisphenol A epoxy resin E-54 188 g, diisoprene diepoxide (ERL-4269) 85 g, catalyst triphenylphosphine 0.8 g, di Ethylamine 1.0g, methacrylic acid 153g, other conditions are the same as embodiment 1, get epoxy acrylate resin 426g, sampling test, the results are shown in Table 1.

[0043] When preparing the photocurable resin composition of the present invention, the epoxy acrylate resin consumption is 172g, reactive diluent 1,4-butanediol diacrylate 20g, benzyl acrylate 10g, plasticizer dioctyl phthalate 15g of ester, 3g of photocuring agent KIP 150, no filler, and other conditions were the same as in Example 1, and 204g of photocurable resin composition was obtained. The resin composition and samples were sampled and tested, and the results are shown in Table 2.

Abstract

The invention relates to a photo-curable resin composition for repairing a facing marble plank. The photo-curable resin composition comprises the following components in percentage by total weight being 100%: 70-92% of epoxy acrylate or modified epoxy acrylate, 5-30% of reactive diluent, 0-10% of plasticizer, 0.1-3% of photoinitiator and 0-20% of filler The composition is used for spraying or scraping the surface of the plank, can be fast cured by being irradiated by an ultraviolet light source or sunlight to realize repair enhancement and has the characteristics of fast construction speed, energy conservation, good grinding and polishing effects and the like.

Description

[0001] technical field [0002] The invention belongs to a light-curing epoxy acrylate adhesive for stone processing, in particular to a light-curing adhesive for repairing facing marble slabs. Background technique [0003] The surface of the stone is ground and polished to a high gloss before it can be used for building finishes. The structure of marble stone is uneven, there are many joints, fissures and cavities, and the strength is poor. Before grinding and polishing, resin surface coating is often used to solidify, strengthen the surface of the stone, fill the surface, reduce damage during grinding and polishing, and improve surface gloss. The resin used in the prior art, a class is unsaturated polyester resin, and this resin curing speed is faster, and intensity is higher, but anti-yellowing, aging resistance are poor, and environmental pollution is heavier; A class is epoxy resin , this kind of resin has high strength and good aging resistance, but the curing speed i...
