Problems solved by technology

[0003] However, U-PVC pipe fittings have poor thermal stability during processing, high melt viscosity, and poor plasticizing fluidity. In production and application, additives such as stabilizers, plasticizers, and lubricants must be added to process them.
The current U-PVC pipe fittings add more auxiliary materials, but the impact resistance is poor

Abstract

The invention relates to a U-PVC pipe with a high impact resistant performance. The U-PVC pipe comprises the following components in parts by weight: 100 parts of PVC-SG8 resin, 1 to 10 parts of ABS resin powder, 1 to 10 parts of solubilizer, 1 to 10 parts of heat stabilizer, 0.1 to 5 parts of lubricant, 0 to 5 parts of processing modifier, 5 to 50 parts of filling agent, and 0.5 to 5 parts of titanium dioxide. The pipe comprises ABS powder, the chain sections of butadiene rubber of ABS can absorb the impact energy, and thus the pipe can well resist the impact. At the same time, the amount of added ABS powder is little, the influence on the processing property and product stability is small, and the production is barely affected. A proper amount of CPE is added to increase the capacity of the ABS / PVC system, in the microscopic view, the phase separation degree is decreased, and thus the impact resistant effect is enhanced.

Description

technical field [0001] The invention relates to a U-PVC pipe fitting, in particular to a high-impact U-PVC pipe fitting. Background technique [0002] U-PVC general-purpose pipes and fittings are products promoted and used by the Ministry of Construction in the 1990s. Compared with galvanized steel pipes and cast iron pipe fittings, they have the advantages of light weight, low price, corrosion resistance, fast flow rate and convenient installation. , is an ideal replacement product for building water supply pipes. [0003] However, U-PVC pipe fittings have poor thermal stability during processing, high melt viscosity, and poor plasticizing fluidity. In production and application, additives such as stabilizers, plasticizers, and lubricants must be added to process them. The current U-PVC pipe fittings have more auxiliary materials, but the impact resistance is poor. Therefore, it is very necessary to research and develop a U-PVC pipe fitting with less auxiliary materials a...
