[0041] Melamine formaldehyde resin: 50

[0042] Expandable graphite composite phosphorus nitrogen flame retardant: 15

[0043] Titanium dioxide: 10

[0044] Talc: 8

[0045] Dispersant: 5

[0046] Thickener: 3

[0047] Water: add water to 100

[0048] Fireproof decorative finish:

[0049] Hydroxy Acrylic: 15

[0050] Ammonium polyphosphate: 20

[0051] Titanium dioxide: 20

[0052] Zinc Oxide: 8

[0054] Coalescent: 2

[0055] Water: Appropriate amount to 100

experiment example

[0056] Experimental example: The product of Example 1 is coated with a layer according to the conventional coating process, and then the fireproof decorative topcoat layer is thickened to the required thickness, and the performance index is tested. The results are as follows:

[0057] 1. Flame resistance time: 25 minutes (Class I, GB12441-1998)

[0058] 2. Contrast ratio: 0.97 (GB / T9756-2001)

[0059] 3. Alkali resistance: no abnormality within 24 hours (GB / T9756-2001)

[0060] 4. Scrub resistance: ≥1000 times (superior product, GB / T9756-2001)

[0061] 5. VOC: 34 (qualified, GB18582-2001)

[0062] 6. Free formaldehyde: 0.008 (qualified, GB18582-2001)

[0063] According to the test results, the fire-proof decorative wall coating with dual-core structure of the present invention can not only meet the fire-proof requirements of GB12441-1998, but also meet the performance indicators of GB / T9756-2001.

Embodiment 2

[0064] Embodiment 2: the present embodiment is a preferred embodiment

[0065] Fireproof primer:

[0066] Urea-formaldehyde resin: 10

[0067] Expandable graphite composite phosphorus nitrogen flame retardant: 35

[0068] Titanium dioxide: 20

[0069] Talc: 5

[0070] Water: up to 100

[0071] Fireproof decorative finish:

[0072] Hydroxy Acrylic: 30

[0073] Ammonium polyphosphate: 10

[0074] Titanium dioxide: 10

[0075] Zinc oxide: 10

[0076] Calcium carbonate: 10

[0077] Dispersant: 2

[0078] Wetting agent: 2

[0079] Coalescing aid: 0.5

[0080] Thickener: 2.5

[0081] Fungicide: 1

[0082] Water: Add appropriate amount to 100

[0083] The application of this embodiment is the same as that of Example 1. First, apply a fireproof primer to form a primer layer. After drying, apply a fireproof decorative topcoat to form a topcoat layer and thicken to the desired thickness. The effect of the experimental example can also be achieved.

Abstract

The invention relates to a fire-resistant decorative wall face coating material with a dual-core structure. The fire-resistant decorative wall face coating material is characterized by comprising two parts, i.e. a fire-resistant priming coat and a fire-resistant decorative finishing coat; the fire-resistant priming coat includes an expandable flame retardant and priming coat film-forming substances; and the decorative finishing coat includes finishing coat film-forming substances and an incarbonization catalyst, wherein the finishing coat film-forming substances can be subjected to crosslinking reaction with the priming coat film-forming substances so as to form meshed crosslinked ultra-high molecules. The priming coat and the finishing coat are formed by compounding organic and inorganic materials; and meanwhile, the priming coat and the finishing coat exert synergistic reaction when a fire occurs, and thus, an effect that the priming coat carries out fire resisting and heat insulation and the finishing coat carries out inflame retarding and smoke purifying is achieved.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a fireproof decorative wall coating. Background technique [0002] Today's building decoration materials pay more attention to their functionality than the decoration effect. However, the current decorative wall coatings ignore the fire safety in fires except for the decorative effect. In the domestic building decoration regulations, the requirements for wall coatings, that is, GB / T9756-2001, only specify the physical and chemical performance indicators of interior wall coatings, and do not mention the fire protection requirements; while the domestic fire protection regulations require decorative fire-resistant coatings. GB12441-1998 only stipulates the fire performance index, and its physical and chemical indexes are far from the various indexes stipulated in GB / T9756-2001. As a result, the wall coating does not have the fire protection function, but the decorative fire...
