Problems solved by technology

[0003] At present, the performance of modified plastics with PVC as the main component has been greatly improved, but they still cannot meet higher requirements. Among them, their heat resistance is not good, and their anti-aging performance cannot meet the growing market requirements. Therefore, it is necessary to develop a material with excellent heat resistance and aging resistance to meet the needs of the application.

Abstract

The invention discloses a heat-resisting ageing resistant material and a preparation method thereof. The material comprises following components in parts by weight: 80-100 parts of polyvinyl chloride (PVC), 10-20 parts of bisphenol A epoxy resin, 5-10 parts of toluene diisocynate, 0.8-2 parts of lignin calcium sulfonate, 8-15 parts of polyethylene glycol 600, 6-15 parts of styrene, 5-10 parts of stabilizer, 1-5 parts of lubricant, 2-6 parts of acrylamide, and 0.5-3 parts of antioxidant. The preparation method comprises the steps of adding the PVC, bisphenol A epoxy resin, styrene, stabilizer and antioxidant into a mixing blender, mixing at certain conditions, then adding the lignin calcium sulfonate and acrylamide, heating up, then adding the left components, stirring for 10-20 minutes at 80-90DEG C, rising the temperature and reacting, so as to obtain the mixture, and finally, extruding the mixture by a twin-screw extruder so as to obtain the heat-resisting ageing resistant plastic.

Description

technical field [0001] The invention belongs to the technical field of chemical material preparation, and in particular relates to a heat-resistant and aging-resistant material and a preparation method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride polymer), is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80-85°C, and becomes viscoelastic at 130°C , 160 ~ 180 ℃ began to change into a...
