Description
Technical field
The present invention relates to a kind of building and ornament materials, especially relate to a kind of suspended ceiling decoration material.
Background technology
Decorating with the mineral wool acoustic panel and have advantages such as sound-absorbing, heat insulation, lightweight, environmental protection, is ceiling material good in the present building decoration.Starch is spared the easy moisture absorption to because the framework material in the mineral wool decorative board raw material---mineral wool or rock wool, swelling perlite powder, xylon and/or straw fiber etc. and caking agent---, so the also easy moisture absorption of mineral wool decorative plate, and humidity resistance is poor.Very easily cause sagging distortion after the mineral wool decorative plate moisture absorption, influence the quality of furred ceiling engineering and the work-ing life of furred ceiling.Though adopt emulsified olefin as strengthening damp proof material at present in the raw material of traditional mineral wool decorative plate of producing, it is still undesirable that moistureproof problem solves.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of humidity resistance, is difficult for the decorative sheet because of the sagging distortion of the moisture absorption, is used for substituting traditional mineral wool acoustic panel.
Decorative sheet of the present invention by weight percentage, its component consists of:
Framework material: the arbitrary combination of mineral wool or rock wool, xylon and/or straw fiber, swelling perlite powder
Or mineral wool or rock wool 50-90%,
Caking agent: starch or pasted starch 5-30%,
Strengthen damp proof material: sodium alkylsiliconate and/or alkyl potassium silicate 0.2-5%,
Softener material: boric acid and/or zinc acetate 0-3%,
Cover material: kaolin and/or sea bubble 0-20%.
Decorative sheet of the present invention by weight percentage, its preferred ingredient consists of:
Framework material: the arbitrary combination of mineral wool or rock wool, xylon and/or straw fiber, swelling perlite powder
Or mineral wool or rock wool 60-88%,
Caking agent: starch or pasted starch 10-30%,
Strengthen damp proof material: sodium alkylsiliconate and/or alkyl potassium silicate 0.2-3%,
Softener material: boric acid and/or zinc acetate 0-3%,
Cover material: kaolin and/or sepiolite 0-20%.
Decorative sheet of the present invention by weight percentage, its another preferred ingredient consists of:
Framework material: the arbitrary combination of mineral wool or rock wool, xylon and/or straw fiber, swelling perlite powder
Or mineral wool or rock wool 64-84%,
Caking agent: starch or pasted starch 15-25%,
Strengthen damp proof material: sodium alkylsiliconate and/or alkyl potassium silicate 0.2-1%,
Softener material: boric acid and/or zinc acetate 0-3%,
Cover material: kaolin and/or sepiolite 0-20%.
Above-mentioned enhancing damp proof material is to add the neutralization of acidic substance such as mineral acid, organic acid, strong acid weak base salt in sodium alkylsiliconate and/or the alkyl potassium silicate, to its pH value be 5-10.
Decorative sheet of the present invention adopts sodium alkylsiliconate and/or alkyl potassium silicate to do to strengthen damp proof material, and its humidity resistance improves greatly, has also improved the intensity of product simultaneously.Decorative sheet of the present invention generally is difficult for being out of shape because of the moisture absorption, is used for the quality that the furred ceiling engineering can guarantee engineering construction.
Be decorative sheet of the present invention and traditional mineral wool decorative plate performance comparison detected result below.
Detection method is: with traditional mineral wool decorative plate and decorative sheet cut growth 400mm of the present invention, the bar shaped of wide 40mm puts it into relative humidity and is 95%, temperature is in 42 ℃ the humidity cabinet again.Two ends during placement that stripe board is long ride on the case inner support, respectively take about 20mm, and are middle unsettled, close upper chamber door, keep constant humidity and temperature, take out at different time, measure its sagging size, and detected result is as follows:
| Time | 2 hours | 4 hours | 6 hours |
| Decorative sheet sag of chain of the present invention | 0 | 1.5mm | 2.5mm |
| Tradition mineral wool decorative plate sag of chain | 1.5mm | 4mm | 9mm |
From above comparison and detection result as can be known: decorative sheet of the present invention is difficult for sagging distortion under wet condition, and its humidity resistance is better than traditional mineral wool decorative plate greatly; Its intensity also is better than traditional mineral wool decorative plate.
The required raw material of decorative sheet of the present invention all can be bought on market.
The production method of decorative sheet of the present invention comprises the following steps:
1) strengthening damp proof material is to add the acidic substance neutralization in sodium alkylsiliconate and/or the alkyl potassium silicate, to its (when pH value is 5-10, in pony mixer, add required sodium alkylsiliconate and/or alkyl potassium silicate earlier, add the acidic substance neutralization more while stirring gradually, be 5-10 to its pH value, stand-by;
2) when comprising mineral wool or rock wool, xylon and/or straw fiber fiber in the framework material, with required mineral wool or rock wool and weight 20-60 water doubly or required xylon and/or straw fiber and weight 20-50 water doubly thereof, put into stirrer respectively, stir into uniform slurry; When comprising mineral wool or one of rock wool, xylon and/or straw fiber in the 1. framework material, in above-mentioned slurry, add other required framework material, stir, the gross weight that adds water to water again is 20-100 a times of required framework material gross weight, after stirring, add required caking agent more while stirring successively, strengthen damp proof material, softener material and cover material, be stirred to evenly, make uniform raw material slurry; When comprising mineral wool or rock wool and xylon and/or straw fiber in the 2. framework material, two kinds of slurries are sent in the mixing tank, and add required other framework material, stir, the gross weight that adds water to water again is 20-100 a times of framework material gross weight, after stirring, adds required caking agent more while stirring successively, strengthens damp proof material, softener material and cover material, be stirred to evenly, make uniform raw material slurry;
