Abstract

The invention discloses a fabric thermal insulation coating and its preparation method. According to the invention, natural latex, nekal, a stabilizer, a dispersant, a vulcanizing agent, polyvinyl chloride, a promoter, diphenyl guanidine, diethanolamine, 2-aminoethanol, butyl phthalate, hydroxypropyl methyl cellulose, polyvinyl acetate and dithiocarbamate are weighed by weight portion. Technical effects are as follows: surface drying time of the product is 10-25min and hard drying time is 50-65 min; flame resistant time is 35-50 s, and the product has flame resistance; weight loss is 1-4 g; adhesive force reaches up to 100%, and the product will not fall off or mildew after immersed in water for 22-30 d; gloss reaches 93-100%, and flexibility is 1.5-3 mm; and service life of a coating film is long. The product can be widely produced and can continuously replace existing materials.

Description

technical field [0001] The application relates to a paint, in particular to a fabric heat-insulating paint and a preparation method thereof. Background technique [0002] "Heat insulation coating" is a kind of functional coating developed in recent years, which reflects heat and light, has short construction period and quick effect. There are three main classifications of thermal insulation paints from the characteristics and principles: insulating conductive thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings. [0003] Most of the existing heat-insulating coating products are used on the surface of concrete or metal structures to achieve heat-insulating effect. The flexibility, compactness and adhesion of this type of heat-insulating coating are generally poor, so it is not suitable to be painted on textiles for heat insulation. insulation. However, along with the widespread use of outdoor textiles such as tents, p...
