Embodiment 1

[0027] Weigh 500 grams of potassium hexatitanate whiskers and 10 grams of coupling agent for hot mixing, let it cool to room temperature, and then add the mixture, 10 kilograms of PVC-5 resin, and 400 grams of compound stabilizer in a small high-speed mixer in sequence. Agent, 400 grams of ACR, 800 grams of CPE and 2 kilograms of calcium carbonate, hot-mixed and cold-mixed according to the conventional method, the mixed material is injected into a 150-gram injection molding machine to make a sample, and its drop weight impact index (0 °C ambient temperature Under the real impact rate) and ring stiffness index, the measurement results are shown in Table 1.

Embodiment 2

[0029] Weigh 2 kg of potassium hexatitanate whiskers and 40 g of coupling agent for hot mixing, let it cool down to room temperature, then add the mixture, 10 kg of PVC-5 resin, and 400 g of compound stabilizer in a small high-speed mixer. Agent, 400 grams of ACR, 800 grams of CPE and 3 kilograms of calcium carbonate were hot mixed and cold mixed according to conventional methods, and the mixture was injected into a 150-gram injection molding machine to make a sample, and its drop-weight impact index (0°C ambient temperature Under the real impact rate) and ring stiffness index, the measurement results are shown in Table 1.

Abstract

This invention relates to a hard and its preparation method. The feature is that it contains six potassium titanate crystal whiskers, hard chlorethylene tube made by materials in this invention has good low temperature proof capability, wear resistance and corrosion stability.

Description

technical field [0001] The invention relates to a hard polyvinyl chloride (PVC-U) pipe material and a preparation method thereof, in particular to a hard polyvinyl chloride pipe material for manufacturing drainage pipes and a preparation method thereof. Background technique [0002] In the past, the drainage pipes buried in the ground used large-volume pipes such as cast iron pipes or cement pipes. The construction was very troublesome. The cast iron pipes buried underground for a long time had to be replaced every certain number of years, which brought a lot of inconvenience to the project. The traditional cast iron Pipes and cement pipes are gradually replaced by hard polyvinyl chloride pipes. Reinforced pipes and corrugated pipes made of rigid polyvinyl chloride have the characteristics of light weight, low cost, and good corrosion resistance. They do not require frequent maintenance and replacement, and are convenient for construction and installation. But its disadvant...
