Abstract

The invention discloses a novel heat-resistant PVC profile and a preparation method thereof.The novel heat-resistant PVC profile is composed of PVC resin powder and auxiliaries, the auxiliaries are composed of a heat-resistant modifier, a stabilizer, calcium carbonate, a flexibilizer, a processing modifier, titanium dioxide and a lubricant, and the heat-resistant agent is a styrene-butenoic acid-acrylonitrile copolymer; the PVC profile has the advantages that the Vicat softening point can be obviously improved by adding the heat-resistant agent styrene butenoic acid-acrylonitrile copolymer, and on the basis of obviously improving the heat resistance of the PVC profile, the impact strength and the tensile strength can be kept slightly changed, and the overall performance is excellent.

Description

Technical field: [0001] The invention relates to the technical field of new PVC materials, in particular to a novel heat-resistant PVC profile and a preparation method thereof. Background technique: [0002] PVC is one of the five synthetic thermoplastics, its output is second only to polyethylene, and PVC is mainly hard products; PVC profiles are widely used in furniture and decoration industries, and develop at a relatively fast speed, but PVC profiles are not heat resistant. It cannot meet the demand for long-term use under high temperature conditions, which limits its application range. Therefore, improving the heat resistance of PVC profiles is one of the keys to the development and application of PVC profiles, which will promote its application and development in more industries. Invention content: [0003] In order to overcome the common problem of poor heat resistance of PVC materials in the prior art), the present invention provides a novel heat-resistant PVC prof...
