Problems solved by technology

In the prior art, water-based acrylic paints are often used as exterior wall paints for grain storage warehouses, but this paint cannot meet the special requirements for storing grain, such as acrylic paints cannot be heat-insulated and cannot meet the heat-insulation requirements; large-area tortoises often appear cracks, the wall is gradually soaked in water, resulting in a large area of ​​peeling off the wall, which cannot meet the requirements of water resistance and moisture resistance

Embodiment 1

[0029] formula:

[0030] Toluene 40kg 120 # Gasoline 15kg Alkyd resin 8kg

[0031] VAE 4.5kg DBP2kg Neoprene 10kg

[0032] Appropriate amount of pigment;

[0033] Preparation steps: according to the formula requirements, toluene, 120 # Gasoline is metered into the reaction kettle with a high-speed shear emulsifier and mixed fully, then alkyd resin, VAE, DBP, and neoprene are metered in, and the high-speed shear emulsifier is used for shear emulsification at a speed of 1500 rpm , After cutting for 1 hour and 10 minutes, add the pigment, and continue to emulsify and grind. When the fineness of the material reaches below 60 μm, it can be filtered and filled into a finished product.

Embodiment 2

[0035] formula:

[0036] Toluene 50kg 120 # Gasoline 20kg Alkyd resin 10kg

[0037] VAE 8kg DBP5kg Neoprene 20kg

[0038] Appropriate amount of pigment;

[0039] The preparation steps are basically the same as those in Example 1. The rotational speed of the high-speed shear emulsifier is 2000 rpm, and the pigment is added after shearing for 1.5 hours.

Embodiment 3

[0041] formula:

[0042] Toluene 70kg 120 # Gasoline 35kg Alkyd resin 13kg

[0043] VAE 9kg DBP6.5kg Neoprene 35kg

[0044] Appropriate amount of pigment;

[0045] The preparation steps are the same as those in Example 1. The rotational speed of the high-speed shear emulsifier is 2500 rpm, and the pigment is added after shearing for 1 hour and 45 minutes.

Abstract

The invention discloses a radiation reactant exterior wall paint in the field of exterior wall paint producing technology. It is formed by toluene, 120# petrol, alkyd resin, VAE, DBP, chloroprene rubber and painting; it has the following preparing steps: adding the toluene and the 120# petrol into the autoclave sterilizer to mix them, adding the alkyd resin, VAE, DBP and chloroprene rubber and using high speed cutting emulsion machine to do cutting emulsion, adding the painting after 1-2h and emulsion erasing until the material purity achieves to below 60mu m, then filter charging the product.

Description

technical field [0001] The present invention relates to an exterior wall paint, in particular to a solar radiation resistant exterior wall paint which hardly absorbs sunlight. Background technique [0002] Grain storage is a major event related to the national economy and the people's livelihood. The warehouse must meet the storage requirements and must be heat-insulated, water-resistant, and moisture-proof. In the prior art, water-based acrylic paints are often used as exterior wall paints for grain storage warehouses, but this paint cannot meet the special requirements for storing grain, such as acrylic paints cannot be heat-insulated and cannot meet the heat-insulation requirements; large-area tortoises often appear Cracks cause the wall to gradually soak in water, causing large areas of the wall to peel off, which cannot meet the requirements of water resistance and moisture resistance.
