Abstract

The invention relates to a PVC composite film and a preparation method thereof, the PVC composite film is composed of four layers from outside to inside: a low temperature resistant layer, a heat storage layer, an antibacterial layer and an antifogging layer, the heat storage film uses fatty alcohol as a heat storage agent, can well absorb the temperature in a tent and timely feed back the temperature to the low temperature resistant layer, better resists the penetration of cold air, and is not easy to break and damage. Segmented extrusion molding is adopted, the low-temperature-resistant layer, the heat storage layer, the antibacterial layer and the anti-fog layer are subjected to first-stage extrusion firstly and then subjected to second-stage extrusion molding, tiny gaps are formed between the heat storage layer and the antibacterial layer by controlling the confluence temperature, and the service life of the composite film is prolonged.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, in particular to a PVC composite film with functions such as cold resistance, heat preservation and antibacterial and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, outdoor activities have become a new way of leisure. At the same time, due to the uncertainty of the outdoor environment, especially in winter or high altitude areas, outdoor appliances are required to have better performance. Tents are indispensable outdoor appliances, and are often set up outdoors. How to improve the cold resistance and thermal insulation capabilities of tents has attracted more and more attention from outdoor enthusiasts. The fabric of the tent is mainly divided into three parts: the outer tent fabric, the inner tent fabric, and the bottom tent fabric. The fabric of the outer tent is mainly made of nylon, canvas and other materials; the fabr...
