Background technology
Asbestos board is the abbreviation of asbestos fibre cement board, is to use the materials such as asbestos, glass fibre, clay, according to science
Formula produce.There is very strong tension stress, bear pressure, 1400 DEG C or so can be born.Available for adiabatic, thermal insulation separation
Sound, boiler, steel plant, chemical plant, cast aluminium factory etc. and general electrical apparatus insulation.
Existing insulation asbestos board is all to use more traditional mode of production, and efficiency is low, and cost is high, and obtained asbestos
Plate quality is unsatisfactory, and heat preservation and soundproof effect is bad, there is damaged bad maintenance.
The content of the invention
It is an object of the invention to provide a kind of insulating water-proof building heat preservation asbestos board, using flake asbestos, nano diatomite powder
For raw material, prepared using platen press, preparation technology is simpler, is easy to industrialization, lower cost for material.
Technical scheme is as follows:
A kind of insulating water-proof building heat preservation asbestos board, it is made up of following components of following parts by weight meter:Flake asbestos 60-70
Part, nano diatomite powder 12-14 parts, white wall granulated slag 12-15 parts, waste sludge from paper mill 10-12 parts, mineral fibres 8-10 parts, stone
Limestone 5-7 parts, calcium sulfate crystalline substance 3-5 parts, rice husk 12-14 parts, curing agent 2-4 parts, XNBR 2-3 parts, redispersible breast
Rubber powder 2-3 parts, chlorinated paraffin 3-5 parts, UV absorbent 2-4 parts, water 50-60 parts;Its preparation method comprises the following steps:
(1)By limestone, calcium sulfate is brilliant, white wall granulated slag, rice husk, waste sludge from paper mill, into powder, add through mechanical crushing
Water inventory 20%-30% water, 8-10 minutes are stirred, then the d flash burnings 2-3 seconds under 580-650 DEG C of high temperature, then quick cooling
It is standby to normal temperature;
(2)Flake asbestos, nano diatomite powder are mixed, by the flake asbestos of the relatively low magnetic field intensity of magnetic separator magnetic separation, then
With Ultrafine Grinding by the flake asbestos fine grinding after magnetic separation to 1000-1200 mesh, add remaining water and be together put into stirring container, fill
Divide stirring, speed of agitator mixing time 15-20 minutes, makes it well mixed, turn into pasty state compound at 800-900 revs/min;
(3)By step(1)、(2)In obtained product be well mixed with other remaining ingredient raw materials, pour into hot pressing die
Compressing, at 75-85 DEG C, the press time drops to normal temperature, removes mould, obtain finished product thermal insulation press temperature in 35-45 minutes, cooling
Asbestos board.
A kind of insulating water-proof building heat preservation asbestos board, it is made up of following components of following parts by weight meter:65 parts of flake asbestos, receive
13 parts of diatomite in powder of rice, 14 parts of white wall granulated slag, 11 parts of waste sludge from paper mill, 9 parts of mineral fibres, 6 parts of limestone, calcium sulfate crystalline substance 4
Part, 13 parts of rice husk, 3 parts of curing agent, 2.5 parts of XNBR, 2.5 parts of redispersable latex powder, 4 parts of chlorinated paraffin, UV inhale
Receive 3 parts of agent, 55 parts of water.
Beneficial effects of the present invention are as follows:
The present invention uses flake asbestos, nano diatomite powder appropriate additive to be added, by dispensing, shaping, baking for raw material
Dry, cutting, suitable for insulation, adiabatic, sound damping applications, prepared using platen press, preparation technology is simpler, is easy to industrialization, material
Cost is cheap.
