Abstract

The invention discloses special PVC (polyvinyl chloride) modified granules for gabion mesh covering. The special PVC modified granules are characterized by being prepared from components in parts by weight as follows: 100 parts of PVC resin powder, 20-30 parts of a liquid plasticizer, 5-10 parts of an auxiliary liquid plasticizer, 2-5 parts of a solid plasticizer, 1-3 parts of a heat stabilizer, 5-10 parts of an antioxidant, 3-6 parts of an internal lubricant, 1-3 parts of an external lubricant, 0.5-1 part of a processing modifier and 5-10 parts of a reinforced modifier. The prepared special PVC modified granules for gabion mesh covering are smooth in surface and high in glossiness and has excellent weather resistance and excellent hydrochloric acid corrosion resistance, and a prepared gabion mesh completely meets various requirements of field application.

Description

technical field [0001] The invention relates to a special PVC modified granular material for gabion covering. Background technique [0002] PVC used to be the most produced plastic in the world. Because of its simple production, good insulation and flexibility, it is widely used in daily necessities, artificial leather, pipes, wires and cables, etc. However, due to its poor thermal stability, poor mechanical properties, poor aging resistance, poor cold resistance and other shortcomings, its application is subject to many restrictions. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a special PVC modified pellet for gabion mesh coating, the pellet has a smooth surface, high gloss, excellent weather resistance, and excellent Excellent salt corrosion resistance; the gabion mesh prepared by using the pellets can meet the application requirements in many fields such as ...
