Special polyvinyl chloride/gull stone multifunctional material for agricultural plantation and cultivation

Abstract

A special polyvinyl chloride / gull stone multifunctional material for agricultural plantation and cultivation comprises 30-90 parts of PVC resin, 0.1-10 parts of a gull stone negative ion additive, 0-10 parts of a reinforcing agent, 4-20 parts of a plasticizer, 0-9 parts of a foaming agent and 0-9 parts of a stabilizer. The gull stone negative ion additive is composed of materials releasing negative ions, comprising opal, tourmalinite, mineral fossil and an assistant, and has the functions of negative ion releasing, fatigue alleviating, mind easing, various peculiar smell expelling and air purifying.

Description

technical field

[0001] The invention belongs to the fields of polymer material modification, chemical engineering, composite materials, material processing, and special materials for agricultural planting and breeding, and has wide application value. Background technique

[0002] PVC is one of the five general-purpose synthetic resins in synthetic materials. Its output is second only to polyethylene. It is one of the most widely used plastics in the world. Agricultural plastic products have been widely used in agriculture, forestry, animal husbandry and fishery in my country. industry, and agriculture has become the second largest consumption field of plastic products after the packaging industry. The main raw material of PVC sheet and breeding pipe is polyvinyl chloride, which has strong chemical corrosion resistance and stable performance. It can ensure the long-term usability of the sheet and piping system when storing soil under various conditions and transporting water c...
