Description
Technical field
The invention discloses a kind of preparation method of crack resistance type waterproof gypsum board, belong to sheet material preparing technical field.
Background technology
Waterproof gypsum board refers to this slabstone, and when making waterproof test according to U.S.ASTM standard, its water absorption rate is 5%, i.e.,
Can be used in the larger region of humidity, such as toilet, shower room and kitchen, the plate be added in gypsum core it is quantitative anti-
Aqua, make gypsum that there is certain water resistance in itself.In addition, gypsum paperboard also uses water-proofing treatment, so this is a kind of compares
The good sheet material with more extensive use.But this plate is not directly in moist environment, when also not directly intaking long
Between soak.
The plasterboard of China has：Three kinds of Thistle board, fibrous plaster and hollow gypsum batten：1. Thistle board is
Using gypsum as core, paper is covered on two sides to be strengthened and manufactured light sheet；2. fibrous plaster is using gypsum as binder materials, with each
Kind organic or inorganic fiber（Such as paper fiber, vegetation fiber, glass fibre）The manufactured light sheet as reinforcing material is thick
For 8~12 millimeters, weight is 7~9 kg/ms；3. hollow gypsum batten, and using gypsum as binder materials, blend various lightweights
Material or reinforcing fiber（Such as expanded vermiculite, expanded perlite, glass fibre）Manufactured hollow partition board, the milli of thickness 60~100
Rice, wall weigh 40~60 kg/ms.It is skeleton composition partition wall that paper and fibrous plaster thin plate, which are needed with steel, wood, gypsum stud,.It is empty
For heart gypsum lath because itself having certain rigidity, partition wall can be formed by being not required to skeleton.Gypsum sheet material is easy to cutting processing, but
It is easily damaged, therefore special-purpose machines and tools is needed in transport and installation process., should to ensure that piece will not ftracture during construction and installation
Pay attention to plate stitch position arrangement, edge joint position must be dealt carefully with special cementing material.
In addition, the purposes of plastering is also being widened, in addition to base lining is made, surface decoration material is also served as, even serving as ground
Face brick, exterior wall substrate and wall core etc..
The light partition wall formed with gypsum thin plate or hollow gypsum batten, can be used to separate the interior space, have construction letter
It is single, it is easy to the characteristics of processing is with installation.In the 1970s, China starts to Paper-faced gyp thin plate and the progress of hollow gypsum batten
Experiment and production, and applied in architectural engineering.It is mainly used in the larger space decoration of ambient humidity, such as toilet, shower room
With kitchen etc..It is also widely used in the internal partition wall of the various buildings such as house, office building, shop, hotel and industrial premises, wall covers
Panel（Instead of floated coat）, ceiling, abatvoix, ground layer plate and various decorative panels etc..But plasterboard is deposited at present
Moisture protection is poor and the defects of easy cracking, it is necessary to which we are improved to these defects.
Therefore invent a kind of crack resistance type waterproof gypsum board has positive effect to sheet material preparing technical field.
The content of the invention
The technical problems to be solved by the invention：For current plasterboard exist moisture protection it is poor and easily ftracture lack
Fall into, there is provided a kind of preparation method of crack resistance type waterproof gypsum board.
