Abstract

The invention provides a polymer reinforced light weight gypsum decorating material, which is characterized in that: 100 weight portions of gypsum raw material are added with the following weight portion of materials: 0.5 to 20 portions of polymer reinforcing material, 40 to 60 portions of water, 0.02 to 4.5 portions of a retarder, 4.5 to 45 portions of light weight filling material, 0.4 to 7.5 portions of fiber filling material and 0 to 15 portions of cement. In addition to keeping the excellent shaping ability and molding processability of the original gypsum decorating material, after molding, the volume weight of the polymer reinforced light weight gypsum decorating material is reduced, thus lightening the load of a building structure to a large extend; furthermore, as the formulation and the technique provided by the invention can lead all components to be evenly dispersed in the gypsum raw material so as to ensure adequate use intensity without increasing cost, thus completely solving the problem that the existing gypsum decorating material adds the load of the building structure owing to large volume weight.

Description

Polymer reinforced light gypsum decorative material
Technical field
The present invention relates to a kind of gypsum decorative material, especially a kind of enhancing light gypsum decorative material belongs to technical field of construction and decoration materials.
Background technology
Gypsum is traditional building and ornament materials, has extraordinary figuration ability and moulding processability preferably, and good decorating effect, the traction height, technology maturation is therefore, comparatively extensive in the application of architectural decoration.But passing through years of development and application practice simultaneously, also expose the shortcoming that such material exists---big unit weight is generally 1.3 * 10 3Kgm -3About, the problem of being brought is: the load that increases the weight of building structure.All adopt simple interpolation perlite and glass fiber-reinforced way to reduce unit weight for a long time, though obtained the effect of certain minimizing unit weight, but because of perlite and glass fibre are difficult to form uniform distribution body within it, make the intensity of product be difficult to be guaranteed, the figuration ability also is subjected to certain influence.
Summary of the invention
In order can on the basis that the figuration ability is strong, forming process is good that original gypsum decorative material had, to guarantee enough working strengths, to reduce its unit weight as far as possible, the invention provides a kind of polymer reinforced light gypsum decorative material.
The present invention finishes by following technical proposal: a kind of polymer reinforced light gypsum decorative material, it is characterized in that in mass parts is 100 gypsum raw material, and add following mass parts:
Polymkeric substance supporting material 0.5~20
Water 40~60
Retardant 0.02~4.5
Lightweight filler 4.5~45
Fiber filled material 0.4~7.5
Cement 0~15.
Described polymkeric substance supporting material is selected polyvinyl alcohol for use, Xylo-Mucine, methylcellulose gum, one or more in the Natvosol.
Described light filler material selection aerosil, perlite, instant powder, one or more in the vermiculite.
Described retardant is selected citric acid for use.
Described fiber filled material is selected glass fibre for use, one or more in the polypropylene fibre.
Described cement is white cement or Portland cement, wherein preferably selects white cement for use, and its add-on is selected to add or do not add or add or add less according to the quality situation and the product requirement of raw material, requires to exceed to satisfy quality product.
The present invention is raw materials used to be commercially available technical grade product with auxiliary material.
Polymer reinforced light gypsum decorative material provided by the invention prepares by following processing method:
A, with polymkeric substance supporting material swelling and mixing in 85~100 ℃ water, be cooled to then below 70 ℃, add after retardant mixes, it is stand-by promptly to be mixed with polymer materials water swelling solution, is used for suspended dispersed and reinforcement;
B, with gypsum raw material and lightweight filler, fiber filled material and white cement, perhaps that gypsum raw material and lightweight filler and fiber filled material is mixed that mixed powder is stand-by;
C, the polymer materials water swelling solution of A step gained is sneaked in the mixed powder of B step gained, stirs, inject in-mold molding after, promptly get the polymer reinforced light gypsum decorative material product.
The casting of described C step adopts forming mould of the prior art and moulding process to carry out moulding.
The present invention has following advantage and positively effect: adopt such scheme, can make resulting polymers strengthen the light gypsum decorative material product, outside keeping original gypsum decorative material good figuration ability and moulding processability, comparatively Tu Chu characteristics are: the polymer reinforced light gypsum decorative material unit weight after the moulding is reduced, can make unit weight as required only is the product of the 55-70% of conventional gypsum material, alleviate the building structure loading significantly, simultaneously because prescription provided by the invention and processing method can make each component be evenly dispersed in the gypsum raw material, guarantee that it has enough working strengths, basically do not increase simultaneously product cost, therefore, fundamentally having solved existing gypsum decorative material increases the difficult problem of building structure loading greatly because of unit weight, and the present invention also has raw material and is easy to get, and prescription rationally, science, technology is simple, easy to operate, invest little, free from environmental pollution, characteristics such as energy-conservation adapt to and apply very much.
