Abstract

An adhesive for filling gaps between stones, the adhesive including at least 100 weight parts of an unsaturated polyester resin suitable for air-drying, between 1 and 5 weight parts of hydrogenated castor oil, between 10 and 250 weight parts of a filler, and between 1 and 15 weight parts of an anti-shrinking agent. The adhesive has good permeability and shrinkage resistance, and high brightness after being polished.

Claims

1. An adhesive comprising at least 100 weight parts of an unsaturated polyester resin suitable for air-drying, between 1 and 5 weight parts of hydrogenated castor oil, between 10 and 250 weight parts of a filler, and between 1 and 15 weight parts of an anti-shrinking agent.

2. The adhesive of claim 1, wherein the gas-filling adhesive comprises at least 100 weight parts of the unsaturated polyester resin suitable for air-drying, between 1 and 5 weight parts of the hydrogenated castor oil, between 50 and 200 weight parts of heavy calcium carbonate, between 2 and 10 weight parts of talcum powder, and between 1 and 15 weight parts of the anti-shrinking agent.

3. The adhesive of claim 1, wherein the filler is selected from the group consisting of calcium carbonate, talcum powder, heavy calcium carbonate, quartz powder, dolomite powder, barium sulfate, or a mixture thereof.

4. The adhesive of claim 1, further comprising between 1 and 5 weight parts of an active diluent.

5. The adhesive of claim 1, wherein the anti-shrinking agent is selected from the group consisting of polypropyl acetate, poly(adipate-co-propanetriol), poly vinyl acetate, polyacrylate, polystyrene, polyethylene, polyvinyl chloride, polymethyl methacrylate, or a mixture thereof.

6. The adhesive of claim 1, wherein the unsaturated polyester resin suitable for air-drying is selected from the group consisting of dicyclopentadiene-modified unsaturated polyester resin synthesized using half-esterification, allyl glycidyl ether-modified unsaturated polyester resin, or trimethylolpropane diallyl ether-modified unsaturated polyester resin;

to the unsaturated polyester resin suitable for air-drying, a diluent, accelerator, and inhibitor of polymerization are added according to conventional usage amount.

7. The adhesive of claim 1, comprising 100 weight parts of the unsaturated polyester resin suitable for air-drying, between 2 and 4 weight parts of the hydrogenated castor oil, between 5 and 10 weight parts of the anti-shrinking agent, between 75 and 150 weight parts of calcium carbonate, and between 4 and 8 weight parts of talcum powder.

8. The adhesive of claim 1, further comprising between 5 and 20 weight parts of rutile titanium dioxide.

9. The adhesive of claim 1, further comprising a colored pigment.

10. The adhesive of claim 3, wherein the calcium carbonate used is between 300 and 1,000 mesh on the average.

11. The adhesive of claim 4, wherein the active diluent is selected from the group consisting of styrene, α

-methyl styrene, glycerol diallyl ether adipate, diallyl phthalate, 2-chlorostyrene, p-tert-butyl styrene, or a mixture thereof.

12. The adhesive of claim 6, wherein in the process of the preparation of the unsaturated polyester resin suitable for air-drying, cycloalkane diols, neopentyl glycol, hydrogenated bisphenol A, trans-double dehydration mannitol, or isophthalic acid is added.

13. The adhesive of claim 2, wherein further comprising between 1 and 5 weight parts of an active diluent.

14. The adhesive of claim 2, wherein the anti-shrinking agent is selected from the group consisting of polypropyl acetate, poly(adipate-co-propanetriol), poly vinyl acetate, polyacrylate, polystyrene, polyethylene, polyvinyl chloride, polymethyl methacrylate, or a mixture thereof.

15. The adhesive of claim 2, wherein the unsaturated polyester resin suitable for air-drying is selected from the group consisting of dicyclopentadiene-modified unsaturated polyester resin synthesized using half-esterification, allyl glycidyl ether-modified unsaturated polyester resin, or trimethylolpropane diallyl ether-modified unsaturated polyester resin;

to the unsaturated polyester resin suitable for air-drying, a diluent, accelerator, and inhibitor of polymerization are added according to conventional usage amount.

16. The adhesive of claim 2, comprising 100 weight parts of the unsaturated polyester resin suitable for air-drying, between 2 and 4 weight parts of the hydrogenated castor oil, between 5 and 10 weight parts of the anti-shrinking agent, between 75 and 150 weight parts of calcium carbonate, and between 4 and 8 weight parts of talcum powder.

17. The adhesive of claim 2, wherein further comprising between 5 and 20 weight parts of rutile titanium dioxide.

18. The adhesive of claim 2, wherein further comprising a colored pigment.

19. The adhesive of claim 13, wherein the active diluent is selected from the group consisting of styrene, α
