Abstract

An adhesive including at least 100 weight parts of an unsaturated polyester resin suitable for air-drying, between 0 and 5 weight parts of hydrogenated castor oil, between 1 and 20 weight parts of a nano powder, between 10 and 250 weight parts of a filler, and between 1 and 15 weight parts of an anti-shrinking agent.

Claims

1. An adhesive comprising at least 100 weight parts of an unsaturated polyester resin suitable for air-drying, between 0 and 5 weight parts of hydrogenated castor oil, between 1 and 20 weight parts of a nano powder, 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, comprising at least 100 weight parts of the unsaturated polyester resin suitable for air-drying, between 1 and 3 weight parts of the hydrogenated castor oil, between 3 and 10 weight parts of the nano powder, between 50 and 200 weight parts of the filler, and between 5 and 10 weight parts of the anti-shrinking agent.

3. The adhesive of claim 2, comprising 100 weight parts of the unsaturated polyester resin suitable for air-drying, one weight part of the hydrogenated castor oil, 6 weight parts of the nano powder, 70 weight parts of the filler, and 8 weight parts of the anti-shrinking agent.

4. 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.

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

6. The adhesive of claim 1, wherein the nano powder and the filler are dispersed using ultrasonic wave and stirred at least 1,500 rpm.

7. The adhesive of claim 1, wherein the nano powder is selected from the group consisting of nano silicon dioxide, nano calcium carbonate, nano magnesium silicate, nano calcium oxide, nano alumina, or a mixture thereof.

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

9. 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.

10. The adhesive of claim 5, 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.

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

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

13. The adhesive of claim 8, wherein the filler used is between 300 and 1,250 mesh on the average.
