Embodiment 1

[0063] A heat-insulating waterproof coating, comprising the following components and the mass percentage of each component is:

[0064] Acrylic 8%

[0065] Barium Sulfate 8%

[0066] Zinc Oxide 2%

[0067] Ethylene glycol 3%

[0068] Lotion 33%

[0069] Ethylene glycol diacetate solvent 19%

[0070] Aromatics 8%

[0071] Titanium self-powder 18%

[0072] Thickener 0.2%

[0073] Hydroxyethylcellulose 0.05%

[0074] Defoamer 0.3%

[0075] Antiseptic and bactericidal additives 0.15%

[0076] Dispersant 0.3%.

[0077] In this embodiment, the amount of acrylic resin and ethylene glycol diacetate solvent is less, and the amount of other components is more, so the relative cost is relatively high.

Embodiment 2

[0079] A heat-insulating waterproof coating, comprising the following components and the mass percentage of each component is:

[0080] Acrylic 10%

[0081] Barium Sulfate 7%

[0082] Zinc Oxide 3%

[0083] Ethylene glycol 2%

[0084] Lotion 33%

[0085] Ethylene glycol diacetate solvent 18%

[0086] Aromatics 10%

[0087] Titanium self-powder 16%

[0088] Thickener 0.3%

[0089] Hydroxyethyl Cellulose 0.04%

[0090] Defoamer 0.3%

[0091] Antiseptic and bactericidal additives 0.16%

[0092] Dispersant 0.2%.

[0093] Compared with Example 1, the dosage of each component is moderate, and the product quality is better. A small amount of washing and domestic water produced in the production process, COD is less than 100mg / L, all of which are recycled into the clarification tank, and discharged after clarification.

Embodiment 3

[0095] A heat-insulating waterproof coating, comprising the following components and the mass percentage of each component is:

[0096] Acrylic 12%

[0097] Barium Sulfate 6%

[0098] Zinc Oxide 3%

[0099] Ethylene glycol 1%

[0100] Lotion 34%

[0101] Ethylene glycol diacetate solvent 17%

[0102] Aromatics 12%

[0103] Titanium self-powder 14%

[0104] Thickener 0.4%

[0105] Hydroxyethyl Cellulose 0.03%

[0106] Defoamer 0.2%

[0107] Antiseptic and bactericidal additives 0.17%

[0108] Dispersant 0.2%.

[0109] Compared with Example 2, the consumption of acrylic resin and emulsion increases, while the consumption of other components decreases, and the relative product quality is relatively poor.

Abstract

The invention provides a thermal insulation waterproof paint, which comprises 8 to 12 percent of acrylic resin, 6 to 8 percent of barium sulphate, 2 to 4 percent of zinc oxide, 1 to 3 percent of glycol, 31 t 35 percent of emulsion, 17 to 19 percent of glycol diacetate solvent, 8 to 12 percent of arene, 14 to 18 percent of titanium white, 0.2 to 0.4 percent of thickening agent, 0.03 to 0.05 percent of hydroxyethyl cellulose, 0.2 to 0.4 percent of antifoaming agent, 0.15 to 0.17 percent of anti-corrosion sterilization aid and 0.1 to 0.3 percent of dispersing agent. The thermal insulation waterproof paint has the advantages of no toxic or side effect ingredients, safety and reliability, and good thermal insulation waterproof effect.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a heat-insulating and waterproof coating. Background technique [0002] Heat insulation and waterproof coating is a new type of functional coating developed in recent years with sun protection, heat insulation, waterproof, energy saving and environmental protection. China has a vast territory and many public facilities, especially the roofs of various grain and material warehouse buildings need to be painted with heat-insulating and waterproof coatings to form a thick rubber-like coating film with a high elongation at break, which can withstand the thermal expansion and cooling of building roofs Shrinkage, make up for cracks, and play a good waterproof role. However, some of the existing heat-insulating and waterproof coatings contain toxic by-products, which have potential safety hazards, or their waterproof and heat-insulating effects are poor, and their impact strength is sma...
