▎ 摘 要
NOVELTY - Heat insulation tent fabric comprises a waterproof layer, an airgel insulation layer, a light-absorbing and a heat-generating antibacterial fabric that are arranged from the outside to the inside. The airgel heat insulation layer is made of an airgel heat insulation finishing agent coated on a light-absorbing, heat-generating and antibacterial fabric, in parts by mass, The raw materials for preparing the airgel thermal insulation finishing agent include 10-50 pts. wt. airgel powder, 5-20 pts. wt. titanium dioxide, 10-60 pts. wt. water-based emulsion, 0.5-5 pts. wt. dispersant, 0.5-5 pts. wt. defoamer, 1-3 pts. wt. thickener, 0.1-1 pts. wt. antifungal agent, 0.1-1 pts. wt. pH regulator and 120-200 pts. wt. water. USE - Used as heat insulation tent fabric. ADVANTAGE - The tent fabric has a good thermal insulation effect; integrates a series of functions required by outdoor products e.g. anti-ultraviolet, far-infrared emission, antibacterial, anti-mildew, self-cleaning, waterproof, breathable and moisture-permeable, which greatly improves people's daily life and use comfort. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing Heat insulation tent fabric comprising (i) pretreating light-absorbing and heat-generating antibacterial fabrics; (ii) carrying out airgel heat insulation finishing agent preparation; (iii) carrying out airgel insulation layer preparation by spraying or scraping method, coating the airgel finishing agent on the surface of the antibacterial, light-absorbing and heat-generating fabric, drying it at room temperature for 2-4 hours, placing in an oven and dry it at 70-80°C for 1-2 hours to obtain a composite fabric; (iv) applying waterproof finishing solution on the surface of the composite fabric for waterproof modification treatment, and rolling the composite fabric coated with waterproof finishing solution with a rolling car and quickly passing through two rollers, the pressure is 0.2-0.4 MPa, and then heat setting at 50-60℃.
