Description
Technical field
The invention discloses a kind of preparation methods of moisture-proof plasterboard, belong to plate preparation technical field.
Background technique
Plasterboard is using building gypsum as a kind of material made of primary raw material.It is that one kind is light-weight, intensity is higher, thick
The construction material for spending the better performances such as relatively thin, easy to process and sound insulation insulation and fire prevention is the novel light of current development emphatically
One of lumber.Plasterboard be widely used in the various buildings such as house, office building, shop, hotel and industrial premises it is interior every
Wall, wall cladding boards (instead of floated coat), ceiling, abatvoix, ground layer plate and various decorative panels etc., for interior
Be not advantageously mounted at bathroom or kitchen.
The plasterboard of China's production mainly has: Thistle board, without Thistle board, decorated gypsum board, gypsum hollow item
Plate, fibrous plaster, plaster board, locating-point plasterboard etc..
Thistle board.Thistle board is using Gypsum slurry as sandwich, and two sides paper makees a kind of lightweight made of mask
Plate.Thistle board quality is light, intensity is high, prevents fires, is mothproof, easy to process.Common Thistle board for interior wall, partition wall and
Furred ceiling.Water-fast Thistle board by fire prevention processing can be used for the biggish room metope of humidity, such as toilet, kitchen, bathroom
Wait the liner plate of tilings, metal plate, plastic cover brick wall.
Without Thistle board.It is exactly a kind of board capable of replacing wood board material of superior performance, using building gypsum plaster as primary raw material, with various
Fiber is a kind of building panel of reinforcing material.It is after Thistle board is obtained and is widely applied, another is succeeded in developing
New product.Since appearance eliminates Protecting Paper, whole application ranges of the application range in addition to covering paper cream plate
Outside, also expanded, comprehensive performance is better than Thistle board.
Decorated gypsum board.Decorated gypsum board is added made of a small amount of fibrous material etc. using building gypsum as primary raw material
There are many patterns, the plate of floriation, such as gypsum printing plate, perforation ceiling board, gypsum embossed hung ceiling plate, Paper-faced gyp facing decoration
Plate etc..It is a kind of novel house decorative material, is suitable for medium-to-high grade decoration, has lightweight, fire prevention, moisture-proof, easy processing, peace
Fill the features such as simple.Especially new type resin imitates type veneering water-proofing plasterboard plate face coated with resin, and facing imitates type decorative pattern, tone
Pattern is true to nature, and novel generous, timber intensity height, anti-pollution, easy cleaning can be used for decorated wall surface, do skirting and skirting board etc.,
It is the ideal material instead of lithotome and terrazzo.
Gypsum hollow lath.Gypsum hollow lath be using building gypsum as primary raw material, add appropriate light filler or
A kind of hollow plate made of fibrous material post-processing.This plate does not have to paper and binder, and keel are not had to when installation, is development
Than a kind of faster light weight board.It is mainly used for interior wall and partition wall.
Fibrous plaster.Fibrous plaster is and to add appropriate fibre reinforced materials system using building gypsum as primary raw material
At.The bending strength of this plate is higher than Thistle board, can be used for interior wall and partition wall, timber can also be replaced to make furniture.
In addition to traditional plasterboard, there are also new products to be continuously increased, such as plaster board, refractory slab, heat-insulating shield and gypsum
Composite plate etc..The specification of plasterboard also develops to Gao Houdu, large scale direction.
Straw Thistle board.Different from common Thistle board, it makes to work as because using a large amount of plant straw
The waste on ground is fully used, and not only solves environmental issue, but also increases the income of peasant, and makes the weight of plasterboard
Amount mitigates, and reduces transportation cost, while reducing the consumption 30%-45% of coal, electricity, complies fully with the relevant industry political affairs of country
Plan.In addition, the purposes of plastering is also being widened, in addition to making base lining, also serve as surface decoration material, even serving as floor tile,
Exterior wall substrate and wall core material etc..
But have the following deficiencies: that (1) is easy cracking using plasterboard made from current technology, plasterboard hardness is not very
Firmly, waterproofness does not have calcium silicate board good, has been grown and has been easy to fall off using the time；(2) moisture resistance of plasterboard is poor, most of plasterboard
With water imbibition, every plum rain season is easy to appear moist phenomenon；(3) load-bearing capacity is poor, impact resistance is poor, and plasterboard is general
It is used for making decoration, but is not amenable to acutely high-intensitive hit.
Therefore, develop that a kind of cracking resistance, moisture resistance be good, plasterboard of good impact resistance has plate preparation technical field
Significance.
Summary of the invention
