Embodiment 1

[0018] Now in conjunction with specific example, the present invention will be further elaborated

[0019] The impact modifier uses 5 parts of MBS (methyl methacrylate-butadiene-styrene polymer), the processing aid uses 2 parts of PMMA (polymethyl methacrylate), and the lubricant uses polyester fatty acid ester 1 2 parts, 2 parts of organotin as stabilizer, 30 parts of activated calcium carbonate as filler, 100 parts of polyvinyl chloride.

[0020] According to above-mentioned prescription, utilize the method for extruder extruding to produce drainpipe (this method is conventional production method), the general production steps are batching, sizing, traction, packing.

[0021] The performance of the pipe made by this formula can meet the requirements of the national standard GB / T5836.1-2006 for rigid polyvinyl chloride drainage pipes.

[0022] See the following table for the physical performance requirements of PVC pipes in GB / T 5836.1-2006:

Abstract

The invention belongs to the field of building materials, relates to a polyvinyl chloride drain pipe, and aims to solve the problems of poorer stability, poorer pipe impact resistance and high production cost during the production of the conventional polyvinyl chloride drain pipe. The polyvinyl chloride drain pipe provided by the invention is made of a stabilizer, filler, a lubricant, an impact modifier, a processing agent and the like. By adopting the technical scheme of the invention, the problems can be effectively solved.

Description

technical field [0001] The invention belongs to the field of building materials and relates to a polyvinyl chloride drainage pipe. Background technique [0002] Due to its convenient processing, polyvinyl chloride is widely used, especially the progress of chlor-alkali industry technology, which promotes the application of polyvinyl chloride more widely. In the field of drainage, especially in the drainage system of buildings, when rigid polyvinyl chloride drainage pipes are used, due to the poor impact resistance of rigid polyvinyl chloride, and in the actual processing process, due to the poor stability of polyvinyl chloride, it is easy to Releases hydrogen chloride to corrode processing equipment. Contents of the invention [0003] The technical problem to be solved by the invention lies in the poor stability of the existing polyvinyl chloride drainage pipe, and a polyvinyl chloride drainage pipe is provided aiming at this problem. [0004] The present invention solve...
