Description of drawings

For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein

Fig. 1 is a kind of structure chart that does not fire the Kang Beite plate of the present utility model.

The specific embodiment

See Fig. 1, present embodiment provides does not fire the Kang Beite plate, comprising: central layer 1 and be located at the surface decoration layer 2 of central layer 1 both sides; Described surface decoration layer 2 comprises facing paper 2-1 and is coated on the resin bed 2-2 of facing paper 2-1 both sides.

The thickness of described central layer 1 is 3-10mm, and the thickness of described facing paper 2-1 is 0.1-0.3mm, and the thickness of described resin bed 2-2 is 0.03-0.05mm.

The component that does not fire the Kang Beite plate (weight ratio) of present embodiment is as follows: fiber 40%, phenol Chuo resin 30%, calcium carbonate 15%, magnesium hydroxide 13.5%, black dyes 1%, coupling agent KH-5500.5%.Above-mentioned component or its raw materials are all from commercially available.

The preparation method of not firing the Kang Beite plate of present embodiment:

Take by weighing by weight fiber and other component is for subsequent use, it is raw material that fiber wherein can adopt tree skill crotch, through washing, fiber is made in defibrator process, and requiring particle size is length 5～10mm, width 0.01～0.5mm, and the calcium carbonate granule diameter is between 0.01～0.5mm, magnesium hydroxide is divided into 9: 1 two parts of sizes, add calcium carbonate, one large magnesium hydroxide in fiber, mix under the high wind effect, and oven dry about 160 ℃.

Magnesium hydroxide, black dyes and the coupling agent KH-550 of aliquot are added in the phenolic resins, mix and be heated to 70 ℃～80 ℃ and make adhesive, adhesive utilizes the high-pressure injection of glue spraying machine to join in the fibre blend of above-mentioned oven dry, glue spraying pressure is 7mpa, after mixing, about temperature 70 C, dry.

Fibre blend machinery on hot press after the glue spraying oven dry is mated formation, and through making central layer 1 behind the precompressed hot pressing, wherein precompressed temperature is 40～50 ℃, pressure 3MPA, 20 seconds time, 150～170 ℃ of hot pressing temperatures, maximum pressure 5MPA and pressure are decremented to zero gradually, 20 seconds time.

Suppress after the both side surface of central layer 1 is pasted facing paper 2-1, make and do not fire the Kang Beite plate, wherein the temperature of compacting is 140～160 degree, and the time is 90 minutes, and pressure is 9MPA.

The preparation method of above-mentioned facing paper 2-1, pressing 1000KG calculates, take by weighing melmac 850KG, light stabilizer 29230KG, ammonium superphosphate 90KG, UV300 ultraviolet money absorbent 30KG joins melmac, mixes and makes resin liquid, facing paper 2-1 is flooded above-mentioned resin liquid, and oven dry is sheared and is formed.

The product Kang Beite plate of present embodiment is according to " GB/T 5464-2010 building product combustibility test " combustion test method measurement result not: variations in temperature is 26.5 degrees centigrade; Mass loss rate is 43%; Without the sustained combustion time.

According to GB/T 14402-2007 construction material combustion heat value determination of test method result: gross calorific value is 1.6MJ/KG, meets A1 rank standard, i.e. variations in temperature in GB 8624-2006 construction material and the goods classification system for fire performance :≤30 degrees centigrade; Mass loss rate :≤50%; Without the sustained combustion time; Gross calorific value :≤2.0MJ/KG.The result is not for firing rank.

Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.

Claims (1)

1. one kind does not fire the Kang Beite plate, it is characterized in that comprising: central layer and the surface decoration layer of being located at the central layer both sides; Described surface decoration layer comprises facing paper and is coated on the resin bed of facing paper both sides;

The thickness of described central layer is 3-10mm, and the thickness of described facing paper is 0.1-0.3mm, and the thickness of described resin bed is 0.03-0.05mm.
