Embodiment Construction

[0015] PVC double-wall corrugated pipe is made of rigid polyvinyl chloride resin as the main raw material. According to the material characteristics of rigid polyvinyl chloride resin-poor impact toughness and the use characteristics of large-diameter buried drainage pipes, it is considered to add Toughened calcium carbonate particles not only improve the toughness of the product, but also improve the ring stiffness of the pipe.

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

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...
