Abstract

The invention discloses a low-odor and low-VOC (Volatile Organic Compound) polyvinyl chloride composite material. The low-odor and low-VOC polyvinyl chloride composite material is prepared from the following components in parts by weight: 100 parts of polyvinyl chloride resin, 35 to 45 parts of plasticizer, 5 to 8 parts of stabilizing agent, 0.3 to 0.8 part of lubricant, 2 to 4 parts of flame retardant, 20 to 40 parts of inorganic filler and 0.3 to 1.0 part of antioxidant. The low-odor and low-VOC polyvinyl chloride composite material and the preparation method thereof, disclosed by the invention, are used for the field of automobile insulating wire harnesses; odorous small molecule substances in the material are adsorbed through zeolite powder and anatase type nano titanium dioxide; a mixing and extrusion technology of PVC is improved aiming at the prior art; a feeding sequence and feeding time are adjusted; the odor grade of the PVC can be reduced when the PVC is produced according to the mixing technology; a special post-treatment technology is increased and finished-product mixing and heat circulating material drying treatment is increased; the obtained product meets basic performance requirements of the automobile wire harnesses and the odor and VOC of the whole automobile are reduced.

Description

Technical field

[0001] The invention relates to the technical field of new materials, in particular to a low-odor and low-VOC polyvinyl chloride composite material and a preparation method thereof. Background technique

[0002] At present, most of the domestic automobile wire industry uses PVC as the basic raw material, adding plasticizers and stabilizers and other additives. Although this kind of automobile wire material can meet the basic performance requirements of automobile wiring harness, it has a large smell and high VOC index. As people's environmental awareness gradually increases, low-odor and low-VOC products will surely become mainstream. The existing technology cannot meet the basic performance of automobile wiring harnesses while meeting the environmental protection indicators of low odor and low VOC.

[0003] Chinese patent CN201510808087.X discloses a low-odor wire and cable sheathing compound, which uses a compound plasticizer and uses a 105°C calcium-zinc stabili...
