Embodiment 1

[0034] The preparation method embodiment 1 of this product is as follows:

[0035] Step 1: Preparation of protective colloid solution

[0036] The raw materials and mass ratio of the protective colloid solution are 3% of industrial grade sodium pyrophosphate, 7% of liquid granite additive (using Laponite RDS of Lockwood Company), 90% of water, and the above-mentioned sodium pyrophosphate, liquid Granite additives and water are dispersed for 20 minutes under the stirring condition of 800r / min, and the density of the protective colloid solution is about 1.003g / cm 3 , until the solution has no particles and is translucent, it is left to age for 24 hours and then it is used for later use.

[0037] Step 2: Preparation of white base paint

[0038] The raw materials and mass ratio of the white base paint are 35% water, 0.8% cellulose (hydroxyethyl cellulose ether ER30M from Dow or cellulose Natrosol 250 HBR from Ashland), 0.6% dispersant (Nopp Polycarboxylate type low-foaming disp...

Embodiment 2

[0048] The preparation method embodiment 2 of this product is as follows:

[0049] Step 1: Preparation of protective colloid solution

[0050] The raw materials and mass ratio of the protective colloid solution are 2% of industrial grade sodium pyrophosphate, 5% of liquid granite additive (using Laponite RDS of Lockwood Company), 93% of water, and the above-mentioned mass parts of sodium pyrophosphate, liquid Granite additives and water are dispersed for 20 minutes under the stirring condition of 1000r / min, and the density of the protective colloid solution is about 1.005g / cm 3 , until the solution has no particles and is translucent, it is left to age for 24 hours and then it is used for later use.

[0051] Step 2: Preparation of white base paint

[0052] The raw materials and mass ratio of the white base paint are 40% water, 0.5% cellulose (hydroxyethyl cellulose ether ER30M from Dow or cellulose Natrosol 250 HBR from Ashland), 0.5% dispersant (Nop Polycarboxylate-type lo...

Embodiment 3

[0062] The preparation method embodiment 3 of this product is as follows:

[0063] Step 1: Preparation of protective colloid solution

[0064] The raw materials and mass ratio of the protective colloid solution are 0.5% of industrial grade sodium pyrophosphate, 3.5% of liquid granite additive (using Laponite RDS of Lockwood Company), 96% of water, and the above-mentioned mass parts of sodium pyrophosphate, liquid Granite additives and water are dispersed for 20 minutes under the stirring condition of 1200r / min, and the density of the protective colloid solution is about 1.006g / cm 3 , until the solution has no particles and is translucent, it is left to age for 24 hours and then it is used for later use.

[0065] Step 2: Preparation of white base paint

[0066] The raw materials and mass ratio of the white base paint are 45% water, 0.3% cellulose (hydroxyethyl cellulose ether ER30M of Dow Company or cellulose Natrosol 250 HBR of Ashland Company), 0.4% dispersant (Nopp Polyca...

Abstract

The invention discloses a method for preparing a weather-resistant artificial granite water-in-water multi-color coating, and belongs to the technical field of a building coating material. The water-in-water multi-color coating adopts an aqueous polymer synthesis emulsion as a base material, kinds of water soluble substances are taken as assistants, so that the multi-color coating is free of ordor and free of pollution. The multi-color coating is simple in preparation technology, low in production cost, economical in construction material, and unique in decorative effect, and is an ideal health interior and exterior wall decoration materials. Compared with the other water-in-water multi-color coating in the market, the product disclosed by the invention has the advantages of being not easy to bleed color points, stable to store, long in expiration date, good in elastic crack resistance and good in weather fastness.

Description

technical field [0001] The invention relates to a preparation method of a paint, in particular to a preparation method of an ultra-stable and highly weather-resistant imitation granite water-in-water multicolor paint. Background technique [0002] The water-in-water type imitation granite colorful paint uses water-based polymer synthetic emulsion as the base material, and various water-soluble substances as additives, so it is odorless and pollution-free. The decorative coating that can imitate the texture and texture of granite after one spraying is an ideal healthy interior and exterior wall decoration material, adding novelty and diversity to architectural coatings. In terms of application, it has the advantages of energy saving, environmental protection, and simple construction. It can replace natural granite and make a substantial contribution to the national building energy saving and consumption reduction. [0003] At present, the main problems of multi-color coating...
