Embodiment 1

[0029] A kind of wall insulation paint, it contains the following components by weight percentage:

[0030] 10% polyurethane foam, 20% acrylic resin, 15% quartz particles, 2% film-forming aid Eastman C-12, 4.5% flame retardant DMMP and the rest water.

[0031] The polyurethane foam is a commercially available product and contains 3 to 10 bubbles per unit volume.

[0032] The preparation method of the coating is as follows: after taking the raw materials according to the ratio, first adding the flame retardant in the ratio on the surface of the polyurethane foam, and then mixing with the rest of the raw materials until evenly dispersed.

Embodiment 2

[0034] A kind of wall insulation paint, it contains the following components by weight percentage:

[0035] 10% polyurethane foam, 15% acrylic resin, 20% quartz particles, 1% film-forming aid Eastman C-12, 4.5% flame retardant DMMP and the rest water.

[0036] The polyurethane foam is a commercially available product and contains 3 to 10 bubbles per unit volume.

[0037] The preparation method of the coating is as follows: after taking the raw materials according to the ratio, first adding the flame retardant in the ratio on the surface of the polyurethane foam, and then mixing with the rest of the raw materials until evenly dispersed.

Embodiment 3

[0039] A kind of wall insulation paint, it contains the following components by weight percentage:

[0040] 15% of polyurethane foam, 20% of acrylic resin, 20% of quartz particles, 2% of film-forming aid Eastman C-12 and the balance of water.

[0041] The polyurethane foam is a commercially available product, which contains 5 to 10 bubbles per unit volume, and is prepared according to the following method:

[0042] Synthesize and foam polyurethane solids from two components of MDI (isocyanate) and polyether polyol in equal proportions at 20°C and normal pressure, then extrude and grind to 28-30 mesh, and then undergo conventional surface treatment. .

[0043] The preparation method of the coating is as follows: take the raw materials according to the ratio and mix them until they are uniformly dispersed.

Abstract

The invention provides heat-insulating coating for a wall body. The heat-insulating coating comprises the following components in percentage by weight: 10-15 percent of polyurethane foam, 15-20 percent of acrylic resin, 15-20 percent of quartz particle, 1-2 percent of film coalescing aid and the balance of other additives and water. The heat-insulating coating can realize technical effects of simpleness and convenience in construction, reduced work procedures, shortened labor time, fire resistance, flame retardance, prolonged service life and the like. The heat-insulating coating is an assurance product for environment friendliness and energy economization of residence.

Description

technical field [0001] The invention relates to a thermal insulation coating, in particular to a wall thermal insulation coating and a preparation method thereof. Background technique [0002] The wall insulation materials and their main limitations in the prior art are as follows: [0003] 1. Rubber powder polystyrene particle external wall insulation system: the required insulation layer is too thick, and the outside needs to be hung with nets and anti-cracking mortar, and the construction process is complicated. (JG 158-2004 Rubber powder polystyrene particle external wall insulation system); [0004] 2. The external thermal insulation system of the external wall with thin plastering of expanded polystyrene board: it is necessary to nail and hang the board, hang the net, and then apply anti-cracking mortar. Expansion and cracking, loss of insulation effect. (JG 149-2003 expanded polystyrene board thin plaster external wall external insulation system); [0005] 3. Spra...
