If it is used for covering a large area or a large tent, the overall weight may reach tens or even hundreds of kilograms, and manual construction is time-consuming and laborious, which is extremely inconvenient
[0005] 2. Poor weather resistance and long service life: When PVC tarpaulin is used for outdoor coverings and tents for a long time, PVC has poor stability to light and heat. It will decompose and produce hydrogen chloride when it is above 67°C or exposed to sunlight for a long time. And further automatic catalytic decomposition, causing discoloration, rapid decline in physical and mechanical properties, the service life does not exceed one year and needs to be replaced, which is a huge waste
Due to the hydrolysis resistance of the TPU tarpaulin, the anti-seepage and anti-mildew properties are also relatively reduced.
[0007] 4. Poor low temperature resistance: The glass transition temperature of PVC is 77~90°C. Although a large amount of plasticizer has been added in the production process, the cold resistance temperature reaches minus 10°C; but in high latitude areas in winter, When the temperature is lower than minus 25°C, PVC tarpaulin products will still become hard and brittle. After being folded or subjected to external forces, the plastic layer on the surface of the tarpaulin is more likely to crack
[0008] 5. Poor mechanical properties: The polyvinyl chloride (PVC) coating layer of PVC tarpaulin has general film-forming properties and cannot provide e

Abstract
An ethylene-octene copolymer tarpaulin includes a polypropylene woven fabric, a glossy POE lamination layer is arranged on the polypropylene woven fabric, and a matte POE lamination layer is arrangedunder the polypropylene woven fabric; the thickness of the glossy POE lamination layer is 0.13-0.15 mm, and the gram weight of the glossy POE lamination layer is 115-136 g/m<2>; the thickness of the matte POE lamination layer is 0.10-0.13 mm, and the gram weight of the matte POE lamination layer is 90-115 g/m<2>; and the gram weight of the polypropylene woven fabric is 170 g/m<2>. Ethylene-octenecopolymer POE is used as a carrier, and is blended with EEA and HDPE polymer plastics to achieve blending modification, and maleic anhydride grafted PP is added to the lamination layers as a binding aid to improve the binding fastness of the polypropylene fabric of the lamination films. The composition components of the tarpaulin, and the ratio thereof are reasonable, and an extrusion casting process is adopted; and the obtained POE lamination layers have the advantages of excellent performances, light weight, long service life, good low temperature resistance, good aging resistance, good water resistance, good mildew resistance, environmental protection and renewability.
Description
technical field [0001] The invention relates to the field of tarpaulins, in particular to an ethylene-octene copolymer tarpaulin and a processing technology thereof. Background technique [0002] Tarpaulin is also called tarpaulin, rain cloth, tarpaulin, and tarpaulin. The fabric is strong and resistant to folding, and has good waterproof performance. It is widely used in automobile transportation, covering open warehouses, and setting up tents in the wild. Traditional tarpaulins include waxed cloth, cotton cloth, silicone canvas, tarpaulin, colored striped cloth, etc., which have simple structure, no plastic layer protection, and poor waterproof, mildew-proof, cold resistance, and aging resistance. With the improvement of people's living standards, the demand for field tents, pick-up canopies, rafting boats, various large and small inflatable toys, jumping beds, pools, and building canopies is increasing. The application range of tarpaulins Gradually expanding, the perform...
