Problems solved by technology

[0003] However, at present, ordinary PVC pipe materials have poor wear resistance and poor toughness, so the service life is short, and they are not suitable for use in harsh environments. In the prior art, there are PVC pipes with wear-resistant components, but the wear-resistant effect and toughness are high-temperature resistant. The effect is poor. Moreover, since the current development of PVC pipes is in a period of rapid development and the industry's production capacity continues to expand, many small and medium-sized enterprises have filled the formula with a large amount of calcium carbonate in order to seize the market and reduce costs, which has affected PVC pipes. The image of the entire industry directly affects the PVC market share and accelerates the loss of PVC market share

Embodiment Construction

[0018] A wear-resistant and toughened PVC pipe modified by adding a rare earth coupling agent to activate vermiculite, characterized in that the PVC pipe includes PVC resin, filler, stabilizer and plasticizer; the filler is a rare earth coupling agent Activated vermiculite, the stabilizer is a calcium-zinc composite heat stabilizer, and the plasticizer is chlorinated polyethylene.

[0019] Relative to 100 parts by weight of the PVC resin, the filler is 8-10 parts, the stabilizer is 4-6 parts, and the plasticizer is 15-20 parts.

[0020] The preparation method of described rare earth coupling agent activated vermiculite is:

[0021] (1) Dry the vermiculite in an oven at 110°C for 2-3 hours, cool to room temperature and grind it through a 200-300 mesh sieve to obtain vermiculite powder;

[0022] (2) Put the vermiculite powder in a high-speed kneader, control the speed at 600r / min and stir for 20-30min, wait until the temperature rises to 100-110°C, keep the temperature constant...

Abstract

The invention discloses an abrasion-proof toughened PVC pipe modified by addition of rare earth coupling agent activated vermiculite and a preparation method thereof. The rare earth coupling agent activated vermiculite is used as packing and added into raw materials, the adding amount is small, and the cost is low; the vermiculite is treated with a rare earth coupling agent, the rare earth coupling agent can play a role in coupling, and a firm wrapping layer is formed on the surface of vermiculite powder due to the unique outer shell structure of rare earth elements, so that inorganic rigid particles with rare earth coordination compounds as shells and vermiculite particles as cores are formed, and the inorganic rigid particles have a high toughening and modification effect on the PVC pipe; meanwhile, organic modification treatment of the vermiculite enhances the interface bonding strength with matrix resin, and a liminated structure is likely to be stripped in the rubbing process, so that the abrasion-proof performance of the PVC pipe is effectively improved.

Description

technical field [0001] The invention relates to the field of PVC pipe production, in particular to a wear-resistant and toughened PVC pipe modified by adding a rare earth coupling agent to activate vermiculite and a preparation method. Background technique [0002] As one of the products of scientific and technological development, PVC pipes are widely used in water supply, building drainage, sewage, chemical and other technical fields because of their strong corrosion resistance, high strength, and good rigidity. Such as various water supply and drainage pipes made of PVC materials. [0003] However, at present, ordinary PVC pipe materials have poor wear resistance and poor toughness, so the service life is short, and they are not suitable for use in harsh environments. In the prior art, there are PVC pipes with wear-resistant components, but the wear-resistant effect and toughness are high-temperature resistant. The effect is poor. Moreover, because the current developmen...
