Color rubber and plastic heat-insulating material and preparation method thereof

Abstract

The invention relates to a color rubber and plastic heat-insulating material and a preparation method thereof. The rubber and plastic heat-insulating material is prepared from polrvinyl chloride paste resin, dinitrosopentamethylene tetraamine, an antiager, styrene rubber, protective wax, an antioxidant, chlorosulfonated polyethylene rubber, diphenyl guanidine, mercaptobenzothiazole, zinc dibutyl dithiocarbamate, zinc diethydithiocarbamate and the like. The performance and the color difference of the product are stabilized by adding a coloring material to perform banburying on the finished rubber again and combining a new vulcanizing foaming technology and a super-long water-cooling system; the prepared color rubber and plastic heat-insulating material does not have fibers and dust, prevents dew formation, has a smooth surface and high cleanliness, has the same bright color as equipment, is environmentally-friendly and non-toxic, reduces secondary construction, saves cost, greatly improves the using performance of the product, prolongs the service life and takes full advantage of the product performance.

Description

technical field [0001] The invention relates to the field of heat insulation materials for buildings and equipment, in particular to a colored rubber and plastic heat insulation material for building or equipment heat insulation that requires color changes and a preparation method thereof. Background technique [0002] The heat insulation materials on the market today have a single color, which is not suitable for some occasions that need to coordinate colors and pay attention to aesthetics. When the heat insulation material needs to be in the same color as the equipment, it is often used to paint the surface of the heat insulation material. After the paint is used for a long time, the protective layer will lose its shielding effect on chemical corrosion media, oxygen, and moisture, resulting in cracks on the surface and affecting the appearance. And greatly destroy the performance of its thermal insulation material. Due to the relatively short assembly line in the existing...

[0002] The heat insulation materials on the market today have a single color, which is not suitable for some occasions that need to coordinate colors and pay attention to aesthetics

When the heat insulation material needs to be in the same color as the equipment, it is often used to paint the surface of the heat insulation material. After the paint is used for a long time, the protective layer will lose its shielding effect on chemical corrosion media, oxygen, and moisture, resulting in cracks on the surface and affecting the appearance. And greatly destroy the performance of its insulation material

Due to the relatively short assembly line in the existing preparation process of colored rubber and plastic thermal insulation materials, the colored rubber and plastic thermal insulation materials cannot be uniformly foamed during foaming in the drying tunnel, and the closed foam rate cannot meet the requirements; the cooling water tank is also relatively short. After the crossing comes out, because the cooling water tank is short, the air temperature and the temperature of the cooling water tank are unstable, so the internal structure of the colored rubber and plastic insulation material cannot be stabilized, making the product weak in water vapor penetration resistance, low in tear strength, and uneven in color distribution; and In the process of rubber mixing, the existing thermal insulation materials only have one internal mixing and two opening kneading, which cannot stabilize the product itself and maintain the best foam structure, and are prone to shrinkage and cracking
