Abstract

The invention discloses a high-content calcium carbonate hard PVC (Polyvinyl chloride) sheet material based on EMO and a processing method thereof. The high-content calcium carbonate hard PVC sheet material is prepared from the following components in parts by weight: 80 to 100 parts of PVC resin, 1 to 5 parts of the EMO, 1 to 3 parts of thermal stabilizer, 3 to 8 parts of AIM, 1 to 2 parts of DOTP (Dioctyl Terephthalate), 30 to 50 parts of calcium carbonate and 0.1 to 0.6 part of fatty acid ester. According to the high-content calcium carbonate hard PVC sheet material disclosed by the invention, the AIM and the EMO are compounded, so that the high-content calcium carbonate hard PVC sheet material is toughened by utilizing less AIM and EMO and the high-content calcium carbonate hard PVC sheet material has good workability and is easy to mold; the high-content calcium carbonate hard PVC sheet material has the advantages of simple technology and low processing cost and has a good application prospect.

Description

technical field [0001] The invention relates to an EMO-based high-calcium carbonate hard PVC sheet and a processing method thereof, belonging to the technical field of PVC sheet product processing. Background technique [0002] Polyvinyl chloride (PVC) plastic is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Due to the nature determined by its molecular structure, pure polyvinyl chloride resin cannot be directly thermoformed. It must be added with impact modifiers, stabilizers, fillers, etc. to improve performance, and made into polyvinyl chloride formula materials, and then processed into various types PVC sheet products. [0003] Among them, calcium carbonate is the most widely used inorganic filler in PVC sheet. Adding calcium carbonate to PVC sheet can improve the heat resistance, wear resistance, dimensional stability and rigidity of the product, and reduce the cost of the product. However, due to the hydrophilic and oleophobi...
