Abstract

The invention discloses a soft polyvinyl chloride material and a preparation method thereof. The soft polyvinyl chloride material of the present invention comprises the following components in parts by weight: 20-60 parts of polyvinyl chloride; 20-60 parts of plasticizer; 0-60 parts of filler; 0-5 parts of stabilizer; 0-5 parts of other additives; wherein the plasticizer contains at least two different kinds of plasticizers. The present invention prepares a soft polyvinyl chloride material with low temperature sensitivity by selecting two or more different types of plasticizers as the plasticizing composition and polyvinyl chloride resin; on this basis, through further Optimization, through the selection of polyvinyl chloride resin combinations with different K values, the addition of mineral fillers, and composition, can further reduce the sensitivity of soft polyvinyl chloride materials to temperature, and increase the applicability and practicability of materials.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride materials, in particular to a polyvinyl chloride material with low temperature sensitivity and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is the plastic with the largest performance span and the widest range of applications. It can manufacture rigid products with high strength and hardness, such as pipes, pipe fittings, profiled materials for doors and windows, bottles and sheets, and electrical and electrical appliances. etc.; it is also possible to manufacture soft soft products by adding plasticizers, such as films, wires and cables, artificial leather, toys, etc. It can be seen that polyvinyl chloride (PVC) plastics are involved in many industries and are the basic chemical raw materials of the national economy. The relationship between economic development is very close. In recent years, with the rapid development of the national economy, my country's ...
