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 nano-SiO 2 The particle diameter is between 20-30nm.

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 112 degrees, the T of sample 2 g The temperature is 87 degrees; the secondary injection molding rate of sample 1 is 97%, 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 began to turn yellow after 322; sample 2 began to turn yellow after 144 days. After adding maleic anhydride, sample 1 began to turn yellow after 368 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 has also been significantly enhanced compared with sample 2.

Abstract

The invention provides a heatproof, wearproof and aging-resistant PVC elastomer material. By adding CPVC resin, an aluminate coupling agent, phosphite ester, polyol and aluminium hydroxide and other ingredients, and defining the content of each component, the added ingredients can reach a very good synergistic effect. On the basis of maintaining an original high secondary injection molding rate, the PVC elastomer material has substantially strengthened heat resistance and wear resistance, and is difficult to age. The service life of the PVC elastomer material is long, and its mechanical properties are also enhanced by certain degree.

Description
