Abstract

The present invention relates to a PVC sealant, wherein the raw materials comprise, by weight, 400-800 parts of a polyvinyl chloride paste resin, 8-20 parts of a foaming agent, 400-800 parts of a plasticizer, 8-20 parts of a stabilizer, and 8-20 parts of titanium dioxide powder. The sealant preparation method comprises: carrying out mixing stirring on the polyvinyl chloride paste resin, the foaming agent and the plasticizer for 8-30 min, adding the stabilizer, stirring for 8-30 min, adding titanium dioxide powder, and stirring for 8-30 min so as to obtain the PVC sealant. According to the present invention, the sealant does not contain bisphenolA, epoxy group and other substances, has characteristics of good foaming effect, low price and simple preparation production, completely meets the food glue requirements, and meets the development trend of the future food sealant.

Description

technical field [0001] The invention relates to a PVC sealant and a preparation method thereof. Background technique [0002] Sealant is usually coated on the lid of the food jar, and then sealed on the jar body to complete the packaging of the food. At present, raw materials with ingredients such as bisphenol A and epoxy radicals are mostly used for sealants, but such ingredients are not conducive to food hygiene and are easy to contaminate food. Contents of the invention [0003] One object of the present invention is to provide a PVC sealant. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A PVC sealant, its raw materials include: in parts by weight: 400-800 parts of polyvinyl chloride paste resin, 8-20 parts of foaming agent, 400-800 parts of plasticizer, 8-20 parts of stabilizer and 8 parts -20 parts of titanium dioxide. [0006] Preferably, the stabilizer is calcium zinc stabilizer. [0007] Anoth...
