Embodiment 1

[0023] The materials and consumption used in this embodiment are as follows:

[0024] The mineral wool board substrate is purchased from Beixin Group, Long brand mineral wool decorative sound-absorbing board, with a thickness of 18mm;

[0025] The fiber felt is a glass fiber felt, purchased from Kaifeng Yiying Glass Fiber Products Co., Ltd., Yiying brand, with a thickness of 0.50mm and an area density of 60g / m 2 ;

[0026] The surface decoration film is a PVC film, purchased from Guangzhou Yongming Plastic Products Co., Ltd., a brand imitating wood, with a thickness of 0.12mm and an area density of 80g / m 2 , the acrylate pressure-sensitive adhesive for bonding the surface decoration film comes with the surface decoration film;

[0027] The adhesive between the mineral wool board substrate and the fiber felt is polyvinyl acetate, purchased from Beijing Xidema Technology Development Co., Ltd., D160.

[0028] The flame retardant in the glass fiber mat is ammonium polyphosphate...

Embodiment 2

[0036] The only difference between embodiment 2 and embodiment 1 is: the thickness of the mineral wool board substrate is 15 mm; other preparation processes or raw material consumption are the same.

Embodiment 3

[0038] The difference between embodiment 3 and embodiment 1 is only: the consumption of ammonium polyphosphate in glass fiber mat is 5.00g / m 2 ; the amount of flame retardant in the binder is 0.35wt.% to 0.45wt.%; other preparation processes or raw materials are the same.

Abstract

The invention relates to the field of mineral wool acoustic board preparation, in particular to a film-coated sand-blast mineral wool board with high fireproof performance, the film-coated sand-blast mineral wool board comprises a mineral wool board base material, a vinyl acetate adhesive and a fiber mat, a first flame retardant is added into the vinyl acetate adhesive, and a second flame retardant is added into the fiber mat. According to the application, the appropriate adhesive is selected, the appropriate flame retardant is selected and added into the adhesive and the fiber mat respectively, and the proportion is optimized, so that the fireproof performance of the film-coated sand-blasting mineral wool board is improved.

Description

technical field [0001] The present application relates to but not limited to the field of preparation of mineral wool sound-absorbing boards, in particular, relates to a film-coated sandblasting mineral wool board with high fire resistance and a preparation method thereof. Background technique [0002] Mineral wool sound-absorbing panels have developed a mature film-coated sandblasting production process and system that is suitable for the current production status. The film-coated sandblasted mineral wool sound-absorbing panels produced by this technology system have excellent characteristics such as high-end appearance quality, excellent moisture-proof performance, and high strength, and the fine sand particles on the surface can increase the diffuse reflection of indoor light and increase the softness of indoor light. Spend. Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summary is not intended t...
