Embodiment 1

[0013] A heat-resistant wear-resistant anti-aging PVC elastomer material, its components and weight percentages are:

[0014]

[0015]

[0016] The balance is CPVC resin, and the particle diameter of nanometer calcium carbonate is between 30-50nm.

Embodiment 2

[0018] The heat-resistant, wear-resistant and aging-resistant PVC elastomer material in Example 1 (referred to as sample 1) and the existing PVC elastomer material (referred to as sample 2) were compared for heat resistance and secondary injection molding rate.

[0019] The existing heat-resistant and wear-resistant PVC pipes prepare raw materials according to the following weight ratio:

[0020] 50 parts of PVC resin, 2.5 parts of calcium stearate, 1.5 parts of zinc stearate, 1.3 parts of stearic acid, 12 parts of fluorine vinegar, 20 parts of thermoplastic styrene-butadiene rubber, and 80 parts of calcium carbonate.

[0021] After testing, it was found that the T of sample 1 g The temperature is 116 degrees, the T of sample 2 g The temperature is 88 degrees; the secondary injection molding rate of sample 1 is 99%, and the secondary injection molding rate of sample 2 is 97%.

[0022] It can be seen that the heat resistance of the product of the present invention is better, ...

Embodiment 3

[0024] Experimental detection of the service life of sample 1 and sample 2:

[0025] Sample 1 was placed in an outdoor environment with an average temperature of 20 degrees, and it was found that it began to turn yellow after 330 days; sample 2 began to turn yellow after 146 days. After adding maleic anhydride, sample 1 began to turn yellow after 385 days in the same environment.

[0026] It shows that the product of the present invention is not easy to age and has a longer service life. It is found through experiments that the wear resistance of sample 1 is significantly enhanced compared with sample 2.

Abstract

The invention provides a heat-resistant, wear-resistant and aging-resistant PVC (Polyvinyl Chloride) elastomer material. According to the heat-resistant, wear-resistant and aging-resistant PVC elastomer material, through adding ingredients, such as CPVC (Chlorinated PVC) resin, an aluminate coupling agent, phosphite, polyol, aluminum hydroxide and the like, and defining the content of each ingredient, a good synergy among the added ingredients is exerted, the heat resistance and wear resistance are remarkably improved on the basis that the high original secondary injection molding ratio is maintained, the aging is not easy, the service life is long, and the mechanical properties are enhanced to some extent.

Description
