Example Embodiment

[0015] PVC double-wall corrugated pipe is made of hard polyvinyl chloride resin as the main raw material. According to the material characteristics of hard polyvinyl chloride resin-poor impact toughness and the use characteristics of large-caliber buried drainage pipes, consider adding in the formulation design Toughening calcium carbonate particles not only improves the toughness of the product, but also improves the ring stiffness of the pipe.

[0016] According to the special performance requirements of buried drainage pipes, the ring stiffness performance of pipes is its key technical index. After various comparisons and tests, choose SLK-1000 or SLP-1000 or rigid polyvinyl chloride similar to its index Resin is used as a raw material for production.

[0017]

[0018] The formulation system is mainly composed of rigid polyvinyl chloride resin, rare earth heat stabilizer, lubricant, coupling agent, modifier, rare earth modified calcium carbonate, etc.

[0019] The f...

Abstract

Formula for producing polyvinyl chloride double-wall bellow consists of hard polyvinyl chloride resin 100 proportion, rare-earth thermal stabilizer 3-6 proportion, lubricant 1.5-2.5 proportion, coupling agent 0.5-1.0 proportion, acrylic ester 2-4 proportion, modifier 6-10 proportion, rare-earth modified calcium carbonate 10-25 proportion. It substitutes lead stabilizer and can be used for blow-off pipe and environmental-protection construction.

Description

technical field [0001] The invention relates to a formula for producing polyvinyl chloride (PVC) double-wall corrugated pipes, that is, a formula for producing polyvinyl chloride drain pipes with a rare earth heat stabilizer. Background technique [0002] Since traditional drainage pipes mostly use cement pipes or reinforced concrete pipes, they are all rigid pipes, and their service life is generally about 15 to 20 years. Their physical, mechanical and chemical properties are not as good as PVC double-wall corrugated pipes, which are backward and eliminated. product. PVC double-wall corrugated pipe is a structural wall pipe for buried drainage. Because PVC double-wall corrugated pipe has a long service life, it is not easy to break when buried underground, and it is resistant to acid and alkali and a certain temperature, so it is suitable for urban sewage pipes Therefore, in recent years, PVC double-wall corrugated pipes have been vigorously developed and promoted. However...
