The invention relates to the technical field of
polyvinyl chloride composite materials, in particular to a high temperature resistant environment-friendly
polyvinyl chloride (PVC) modified material and a preparing method thereof. The modified material comprises by weight, 80-120 parts of PVC resin, 30-70 parts of filling agent, 31-70 parts of
plasticizer, 1-10 parts of hot-resistant modifying agent, 1-10 parts of
fire retardant, 1-10 parts of stabilizing agent, 5-15 parts of
impact modifier and 0.2-2 parts of lubricating agent. Each
raw material is weighed by weight and mixed after being stirred; the
raw material is squeezed out of prilling through a double-screw extruder and the modified material is available. The
hot temperature resistant performance of the modified material manufactured by the preparing method is fine; the maximum usage temperature can reach up to 135 DEG C. The modified material is environment-friendly and has the advantages of
high intensity, good
flame retardant effects, strong compression performance and
toughness, excellent
processing performance and better comprehensive performance. The preparing method of the high temperature resistant environment-friendly
polyvinyl chloride (PVC) modified material has the advantages of being simple in process, convenient to control and operate, stable in quality, and high in production efficiency. In addition, the preparation method of the high temperature resistant environment-friendly polyvinyl
chloride (PVC) modified material can be used for a large-scale industrial production.
