Abrasion resistant poly(vinyl chloride) plastisol
View Patent ↗An abrasion resistant poly(vinyl chloride) plastisol is disclosed. The plastisol includes an effective amount of polydimethylsiloxane to increase abrasion resistance while not adversely decreasing coefficient of friction. Articles subject to friction, such as industrial power transfer belts, benefit from the abrasion resistant plastisol.
1. An abrasion resistant mixture, comprising:
(a) liquid plastisol comprising plasticizer and polyvinyl chloride resin dispersed in the plasticizer and
(b) an effective amount of polydimethylsiloxane to increase abrasion resistance while not adversely decreasing coefficient of friction,
wherein the mixture is a liquid, and
wherein the effective amount ranges from about 8 to about 13 parts per 100 parts of the polyvinyl chloride resin.
2. The mixture of claim 1 , wherein the effective amount ranges from about 8 to about 10 parts per 100 parts of the polyvinyl chloride resin.
3. The mixture of claim 1 , further comprising an optional additive selected from the group consisting of slip agents, antiblocking agents, antioxidants, ultraviolet light stabilizers, quenchers, plasticizers, colorants, mold release agents, lubricants, antistatic agents, fire retardants, and fillers such as glass fibers, talc, chalk, or clay.
4. The mixture of claim 3 , wherein the optional additive is present in an amount from none at all to about 70 parts per 100 parts of the polyvinyl chloride resin.
5. The mixture of claim 3 , wherein the optional additive is present in an amount from 0 to about 55 parts per 100 parts of the polyvinyl chloride resin.
6. A coating of the mixture of claim 1 .
7. The coating of claim 6 , wherein the effective amount ranges from about 8 to about 10 parts per 100 parts of the polyvinyl chloride resin.
8. The coating of claim 6 , wherein the mixture further comprises an optional additive selected from the group consisting of slip agents, antiblocking agents, antioxidants, ultraviolet light stabilizers, quenchers, plasticizers, colorants, mold release agents, lubricants, antistatic agents, fire retardants, and fillers such as glass fibers, talc, chalk, or clay.
9. The coating of claim 8 , wherein the optional additive is present in an amount from none at all to about 70 parts per 100 parts of the polyvinyl chloride resin.
10. The coating of claim 8 , wherein the optional additive is present in an amount from 0 to about 55 parts per 100 parts of the polyvinyl chloride resin.
11. The mixture of claim 1 , wherein the mixture is in the form of a molded article.
12. The mixture of claim 11 , further comprising an optional additive selected from the group consisting of slip agents, antiblocking agents, antioxidants, ultraviolet light stabilizers, quenchers, plasticizers, colorants, mold release agents, lubricants, antistatic agents, fire retardants, and fillers such as glass fibers, talc, chalk, or clay.
13. The mixture of claim 1 , wherein the mixture is in the form of a coating on an article.
14. The mixture of claim 13 , further comprising an optional additive selected from the group consisting of slip agents, antiblocking agents, antioxidants, ultraviolet light stabilizers, quenchers, plasticizers, colorants, mold release agents, lubricants, antistatic agents, fire retardants, and fillers such as glass fibers, talc, chalk, or clay.
15. A method of using a mixture of claim 1 , comprising the step of applying the mixture to an article.
16. The method of claim 15 , wherein the mixture further comprises an optional additive selected from the group consisting of slip agents, antiblocking agents, antioxidants, ultraviolet light stabilizers, quenchers, plasticizers, colorants, mold release agents, lubricants, antistatic agents, fire retardants, and fillers such as glass fibers, talc, chalk, or clay.
