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 LaponiteRDS 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 of Dow Company or cellulose Natrosol250HBR of Ashland Company), 0.6% dispersant (Nopco Company Polycarboxylate typ...

Embodiment 2

[0047] The preparation method embodiment 2 of this product is as follows:

[0048] Step 1: Preparation of protective colloid solution

[0049] The raw materials and mass ratio of the protective colloid solution are 2% of industrial grade sodium pyrophosphate, 5% of liquid granite additive (using LaponiteRDS of Lockwood Company), 93% of water, and the above 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.

[0050] Step 2: Preparation of white base paint

[0051] The raw materials and mass ratio of the white base paint are 40% water, 0.5% cellulose (hydroxyethyl cellulose ether ER30M of Dow Company or cellulose Natrosol250HBR of Ashland Company), 0.5% dispersant (Nopco Company Polycarboxylat...

Embodiment 3

[0060] The preparation method embodiment 3 of this product is as follows:

[0061] Step 1: Preparation of protective colloid solution

[0062] 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 LaponiteRDS of Lockwood Company), and 96% of water. 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.

[0063] Step 2: Preparation of white base paint

[0064] 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 Natrosol250HBR of Ashland Company), 0.4% dispersant (Nopco Company Polycarboxylate-type low-foaming dispersant SN5040 or Corning low-foami...

Abstract

The invention discloses a preparation method of a highly weather-resistant imitation granite water-in-water multicolor paint, which belongs to the technical field of building coating materials. The water-in-water multicolor paint uses water-based polymer synthetic emulsion as a base material, and various water-soluble substances as auxiliary It is odorless and pollution-free. Its preparation process is simple, its production cost is low, its construction materials are saved, and its decoration effect is unique. It is an ideal healthy interior and exterior wall decoration material. Compared with other materials on the market, this product Water-in-water multi-color paint has the advantages of not easy bleeding of color spots, stable storage, long shelf life, elasticity and crack resistance, and good weather resistance.

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...
