Abstract

The present invention relates to a thermosetting resin composition. The composition comprises from about 20 wt. % to about 70 wt. % of a thermosetting resin, from about 1 wt. % to about 30 wt. % of a curing agent, from about 0 wt. % to about 10 wt. % of an accelerant, a tungsten compound, and an inorganic filler. A prepreg may be prepared in an impregnation manner or a coating product may be prepared in a coating manner. The composition may decrease the thermal expansion coefficient of laminates and may effectively block UV light and decrease the light transmissivity.

First claim

The invention claimed is:

1. A thermosetting resin composition, wherein the thermosetting resin composition comprises a thermosetting resin, an inorganic filler and a tungsten compound, wherein the tungsten compound comprises S and P elements.

2. The thermosetting resin composition of claim 1 , wherein the tungsten compound is selected from the group consisting of an organic tungsten compound, an inorganic tungsten compound, and a combination of organic tungsten compounds and inorganic tungsten compounds.

3. The thermosetting resin composition of claim 1 , wherein the tungsten compound is selected from the group consisting of amine tungsten diisopropyl phosphorodithioate, amine tungsten alkyl(aryl)phosphorothioate, and a combination of amine tungsten diisopropyl phosphorodithioate and amine tungsten alkyl(aryl)phosphorothioate.

4. The thermosetting resin composition of claim 1 , wherein the tungsten compound is in an amount of from about 0.001 to about 30 wt. % of the total mass of the thermosetting resin composition.

5. The thermosetting resin composition of claim 4 , wherein the tungsten compound is in an amount of from about 0.1 to about 15 wt. % of the total mass of the thermosetting resin composition.

6. The thermosetting resin composition of claim 1 , wherein the inorganic filler is selected from the group consisting of silica, boehmite, alumina, talc, mica, kaolin, aluminum hydroxide, magnesium hydroxide, zinc borate, zinc stannate, zinc oxide, titania, boron nitride, calcium carbonate, barium sulfate, barium titanate, aluminum borate, potassium titanate, E-glass powder, S-glass powder, D-glass powder, NE-glass powder, hollow micropowder and boehmite, and a combination of at least two selected therefrom.

7. The thermosetting resin composition of claim 1 , wherein the inorganic filler is in an amount of from about 10 to about 80 wt. % of the total mass of the thermosetting resin composition.

8. The thermosetting resin composition of claim 7 , wherein the inorganic filler is in an amount of from about 20 to about 60 wt. % of the total mass of the thermosetting resin composition.

9. The thermosetting resin composition of claim 1 , wherein the inorganic filler has an average particle size of from about 0.1 to about 100 μm.

10. The thermosetting resin composition of claim 1 , wherein the inorganic filler has an average particle size of from about 0.5 to about 20 μm.

11. The thermosetting resin composition of claim 1 , wherein the thermosetting resin is in an amount of from about 20 to about 70 wt. % of the total mass of the thermosetting resin composition.

12. The thermosetting resin composition of claim 11 , wherein the thermosetting resin is in an amount of from about 25 to about 65 wt. % of the total mass of the thermosetting resin composition.

13. The thermosetting resin composition of claim 1 , wherein the thermosetting resin composition further comprises a curing agent in an amount of from about 1 to about 30 wt. % of the total mass of the thermosetting resin composition.

14. The thermosetting resin composition of claim 13 , wherein the curing agent is in an amount of from about 4 to about 25 wt. % of the total mass of the thermosetting resin composition.

15. The thermosetting resin composition of claim 1 , wherein the thermosetting resin composition further comprises an accelerant in an amount of from about 0 to about 10 wt. % of the total mass of the thermosetting resin composition, excluding 0 wt. %.

16. The thermosetting resin composition of claim 15 , wherein the accelerant is in an amount of from about 1 to about 10 wt. % of the total mass of the thermosetting resin composition.

17. A resin varnish, wherein the resin varnish is obtained by dissolving or dispersing the thermosetting resin composition of claim 1 in a solvent.

18. A prepreg comprising a reinforcing material and a thermosetting resin composition of claim 1 attached on the reinforcing material after impregnation and drying.

19. A laminate comprising at least one prepreg of claim 18 .
