Abstract

The invention provides a micro-foam light gypsum decorative material which is characterized in that: 100 parts by weight (pbw) of gypsum raw material is added with ingredients as follows: 0.01 to 7.5pbw of physical foaming agent, 45 to 60pbw of water, 0.02 to 4.5pbw of retarder, 0.3 to 8pbw of fiber filler and 0 to 15pbw of white cement. The obtained micro-foam light gypsum decorative material not only preserves the excellent molding ability and forming and processing capacity of the original gypsum decorative material, but also can be made into products with the volume weight only being 70 to 95 percent of the traditional gypsum material according to needs, thus greatly lightening the load of a building structure, ensuring even distribution of the components in the gypsum raw material, guaranteeing enough use intensity, ensuring no pollution to environment without increasing product cost basically.

Description

A kind of micro-foaming light gypsum decorative material
Technical field
The present invention relates to a kind of gypsum decorative material, especially a kind of micro-foaming 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 through years of development and application practice, expose also that such material exists congenital shortcoming---unit weight is too big, is generally 1.3 * 10 3Kgm -3About, the problem of being brought is thus: 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
At above-mentioned present situation,, the invention provides a kind of micro-foaming light gypsum decorative material 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 present invention starts with from prescription and technology, in prescription, add pneumatogen, adopt the processing method of little foaming to prepare light gypsum decorative material, both kept the strong and simple sophisticated advantage of complete processing of conventional gypsum finishing material figuration ability, reduce its unit weight again greatly, material is even, realizes lighting, reduce the load of buildings skeleton, guarantee that simultaneously goods have enough working strengths.
Concrete technical scheme of the present invention is: a kind of micro-foaming light gypsum decorative material, it is characterized in that in mass parts is 100 gypsum raw material, and add following mass parts:
Pneumatogen 0.01~7.5
Water 45~60
Retardant 0.02~4.5
Fiber filled material 0.3~8
White cement 0~15.
Described pneumatogen is selected one or more among dimethyl dodecyl amine oxide OB-2, dodecyl sulfate K12, the fatty alcohol polyoxyethylene ether sulfate AES for use, and any one product in the OB-2 series products, any one product in the K12 series products, any one product in the AES series products can both use.
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 white cement, its add-on are selected to add or do not add or add or add less according to the quality situation and the product requirement of raw material, require to exceed to satisfy quality product.
The present invention is raw materials used to be commercially available technical grade product with auxiliary material.
Little foaming provided by the invention strengthens light gypsum decorative material and prepares by following processing method:
A, pneumatogen is dissolved in water and mix, add retardant then and mix to such an extent that the aqueous solution is standby;
B, with gypsum raw material and fiber filled material and white cement, perhaps that gypsum raw material and fiber filled material is mixed that mixed powder is stand-by;
C, the aqueous solution of A step gained is sneaked in the mixed powder of B step gained, stirs the fine and closely woven bubble that produces q.s fully fast and also mix, inject in-mold molding after, promptly get little foaming enhancing 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 gained micro-foaming light gypsum decorative material product, outside keeping original gypsum decorative material good figuration ability and moulding processability, comparatively Tu Chu characteristics are: can make little foaming after the moulding strengthen light gypsum decorative material unit weight and reduce, can make unit weight as required only is the product of the 70-95% 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.
