Description

Technical Field

[0001] The invention relates to the technical field of fabric glue dispensing and dripping, in particular to a composite slurry coating with excellent weather resistance. Background Art

[0002] In the production of products such as artificial turf, carpets, kang rugs, industrial blankets, textile fabrics, floor coverings, cookware insulation materials, non-woven fabrics, and composite fabrics, a slurry with certain waterproof, anti-slip, and heat-insulating properties is often added or scraped onto the surface to enhance aesthetics. However, in practice, existing traditional materials lack superior weather resistance, and the production process of traditional coatings is costly and impractical.

[0003] To this end, we've designed a new, weather-resistant composite slurry coating. Using a drip or dot device, it can be dripped or scraped onto various fabrics to create a desired pattern or three-dimensional dotted coating. After drying, the coating becomes hard on the outside and hollow on the inside, significantly reducing weight while also providing excellent thermal insulation, waterproofing, anti-slip properties, and weather resistance.

[0007] As a further preferred embodiment of the present invention, the coating comprises, by weight: 18 parts of vinyl resin or acrylic resin; 5 parts of PVC resin powder; 3 parts of PCV paste resin powder; 6 parts of calcium carbonate; 2 parts of white carbon black; 0.3 parts of foaming agent; 0.3 parts of accelerator; 0.3 parts of curing agent.

[0008] As a further preferred embodiment of the present invention, the coating comprises, by weight: 20 parts of vinyl resin or acrylic resin; 6 parts of PVC resin powder; 4 parts of PCV paste resin powder; 10 parts of calcium carbonate; 3 parts of white carbon black; 0.5 parts of foaming agent; 0.5 parts of accelerator; 0.5 parts of curing agent.

[0009] As a further preferred embodiment of the present invention: the foaming agent is diisopropyl azodicarboxylate.

[0010] As a further preferred embodiment of the present invention: the accelerator is dimethylaniline.

[0011] As a further preferred embodiment of the present invention: the curing agent is isopropylamine.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The coating is made into a paste-like slurry by mixing multiple raw materials in a certain ratio. After passing through a dripping or dotting device, it can be dripped or scraped onto different fabrics to form a specified pattern or a three-dimensional dot coating. Different colored pigments can also be added to the slurry to adjust it to different colored coating dotting products. After the product is dried, it has the characteristics of being hard on the outside and hollow on the inside, which improves the hardness and plasticity of the product while reducing the weight of the fabric after coating and improving its practicality. At the same time, the surface of the dried product or fabric has good heat insulation, waterproof and anti-slip properties, and has excellent weather resistance. Compared with traditional coatings or PVC materials on the market, this coating has a higher cost-effectiveness. DETAILED DESCRIPTION
