example 1

[0024] Production preparation method and steps:

[0025] (1) Synthesis of modified vegetable oil polyols: 1 Put suitable vegetable oil, dibasic acid, isophthalic acid and neopentyl glycol into the reaction pot at a ratio of 45:10:5:40, and heat to 225°C For the dehydration condensation reaction, use xylene to reflux until the pH value is below 8, and stop the reaction. Steam out the reflux xylene, cool to below 180°C and discharge for later use.

[0026] (2) Preparation of component A: Mix the modified vegetable oil polyol, PPG polyether (L-1000), emulsifier, and water in the ratio of 50:15:0.5:34.5 in step 1, add water first, then emulsifier Slowly add the modified vegetable oil polyol and PPG polyether under the stirring of the homogenizer, mix and disperse to form a milky white emulsion-like aqueous dispersion.

[0027] (3) Component B adopts industrial grade MDI.

[0028] (4) Component C consists of high-strength concrete, CO 2 Absorbent, mixed in a ratio of 90:10, mix...

example 2

[0044] Repeat the production process according to Example 1, but the preparation of component C is as follows: high-strength concrete, 40-mesh to 80-mesh colored quartz sand (filtered in sequence with 80-mesh and 40-mesh sieves, and 40-mesh to 80-mesh quartz sand is selected ) and CO 2 Absorbent, mixed in a ratio of 60:30:10, mixed evenly in a horizontal screw mixer, sealed and packaged.

[0045] Application method and steps:

[0046] (1) Product preparation. Weigh the product by weight: component A: component B: component C: component D=2.8Kg:2.8Kg:14.3Kg:0.04Kg, a total of 19.94Kg / set.

[0047] (2) Prepare a 1m×1m concrete substrate. The requirements for the concrete substrate are the same as those described in Example 1.

[0048] (3) Stir and mix the materials. The process is the same as the description in Example 1.

[0049] (4) Application. The process is the same as the description in Example 1.

[0050] (5) Curing. The process is the same as the description in ...

example 3

[0053] Repeat the production process according to Example 1, but

[0054] (1) Component B uses industrial grade xylylene diisocyanate (XDI).

[0055] (2) The preparation of component C is as follows: high-strength concrete, colored quartz sand of 40 mesh to 80 mesh (filtered sequentially through sieves of 80 mesh and 40 mesh, and the quartz sand of 40 mesh to 80 mesh is selected) and CO 2 Absorbent, mixed in a ratio of 60:30:10, mixed evenly in a horizontal screw mixer, sealed and packaged.

[0056] Application method and steps:

[0057] (1) Product preparation. Weigh the product by weight: component A: component B: component C: component D=2.8Kg:3.2Kg:14.3Kg:0.04Kg, a total of 20.34Kg / set.

Abstract

The invention provides a water-based colored sand self-leveling polyurethane mortar, which can be used as an industrial floor and has excellent properties, such as heavy impact resistance, mechanical heavy load resistance, chemical resistance, etc., and can be used in high temperature and humid environments. The polyurethane mortar of the invention uses colored quartz sand to match the color paste, and the overall coating has sufficient compatibility, which can realize the long-term artistic decoration of the floor. The polyurethane mortar of the present invention adopts modified vegetable oil polyether polyol water dispersion, and diisocyanate, such as diphenylmethane diisocyanate (MDI), and high-performance concrete is cured at the same time, and the colored quartz sand in the system can strengthen The hardness of the coating, the obtained coating is durable and wear-resistant, and has various decorative effects. The polyurethane mortar system of the present invention can also be used for repairing and renovating building entities, or realizing decoration purposes on various substrates, etc.

Description

technical field [0001] The patent belongs to the technical field of building or interior building materials, floors and coatings, and relates to a water-based polyurethane mortar coating, which can especially be used as a decorative floor coating in severe environments. Background technique [0002] Flooring is a chemical coating that covers the surface of the substrate, protects and decorates the substrate, and realizes new properties such as wear resistance, high temperature resistance, low temperature environment, impact resistance, heavy load resistance, and anti-skid. It is widely used in industrial, commercial and in civil buildings. At present, floors are mainly divided into inorganic floors with concrete as the main body, organic floors with organic polymers as the main body, and other ceramic tile gypsum floors. Among them, more than 80% of the organic floor is made of oil-based paint, such as epoxy resin industrial floor, acrylic floor, single / two-component poly...
