Abstract
The present invention relates to decoration material field, more particularly to a kind of string slurry sprayed suitable for GRC and preparation method thereof.The string slurry is prepared by the raw material including following parts by weight：100 parts of sulphate aluminium cement, 5~15 parts of string, 25~55 parts of water, 0~15 part of additive, and 0.5~4 part of glass fibre.The preparation method comprises the following steps：Under the conditions of 15~25 DEG C, the additive is added into the water, after stirring 1min, adds the sulphate aluminium cement, after stirring 2min, the string and glass fibre is added, after stirring 3min, produces.The string pulp density is smaller, and the quality of unit area is smaller, it is easier to carry and transfer, and can follow closely, saw property it is more preferable；It is very suitable for GRC injections, and the bed of material consolidation formed in course of injection is fine and close, is flattened without human assistance, largely reduces human cost.
Description
Technical field
The present invention relates to decoration material field, more particularly to a kind of string slurry and its system suitable for GRC injections
Preparation Method.
Background technology
GRC or GFRC Chinese is glass fiber reinforced cement (concrete) product.Nowadays GRC decorative products are extensive
Applied to all many-sides such as decorating outer wall of building, interior decoration, garden landscape and simulation process.
The material of GRC products is mainly cement, sand, glass fibre, water, pigment and various additives currently on the market.It is existing
Following defect mostly be present in some GRC products：
(1) big as aggregate density using sandstone, large product quality is big, is unfavorable for installing.
(2) bed of material formed using sandstone as aggregate in course of injection is more open, needs human assistance to flatten.
(3) sandstone is high as aggregate product hardness but fragility is also bigger, easily damaged and cracking, can not follow closely, can not
Saw.
The content of the invention
(1) technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of density is small, good toughness and suitable for the plant of GRC injections
Me fibrous slurry.
(2) technical scheme
In order to solve the above-mentioned technical problem, the invention provides it is a kind of suitable for GRC injection string slurry, its by
Raw material including following parts by weight is prepared：100 parts of sulphate aluminium cement, 5~15 parts of string, 25~55 parts of water, outside
Add 0~15 part of agent, and 0.5~4 part of glass fibre.
The parts by weight are the unit of weights well known in the art such as μ g, mg, g, kg, or are its multiple, such as 1/100,1/10,
10 times, 100 times etc..
Further, the string slurry suitable for GRC injections includes the composition of following parts by weight：Aluminium sulfate
100 parts of cement, 8~12 parts of string, 30~50 parts of water, 5~10 parts of additive, and 1.5~3 parts of glass fibre.
Further, the string is sawdust.
Further, the granularity of the sawdust is 2~80 mesh.
Preferably, the granularity of the sawdust is 30~40 mesh.
Further, the additive by water reducer, retarder and thickener according to 1：1：0.15~0.35 mass ratio
Mix, preferably 1：1：0.25 mass ratio mixes.
Further, the string slurry suitable for GRC injections also includes 1~3 part of pigment.
Preferably, the pigment is iron oxide pigment.
Present invention also offers a kind of method for preparing above-mentioned string slurry, this method comprises the following steps：15
Under the conditions of~25 DEG C, the additive is added into the water, after stirring 1min, adds the sulphate aluminium cement, is stirred
After 2min, the string and glass fibre are added, after stirring 3min, is produced.
In addition, the application present invention also offers above-mentioned string slurry in building decoration area, preferably in wall
Application in decoration.
(3) beneficial effect
The above-mentioned technical proposal of the present invention has the advantages that：
The present invention creatively substitutes traditional sandstone using string and is used as bone using sulphate aluminium cement as binder materials
Material, is optimized, obtained string slurry by applying additive and glass fibre, and to the proportioning of raw material, and existing
The slurry using sandstone as aggregate compare：Pulp density is smaller, thus the quality of unit area is smaller, it is easier to carries and turns
Move；And the addition of string causes the toughness increase of slurry, can follow closely, saw property is more preferable；Furthermore the addition phase of string
Usage amount to reducing the higher glass fibre of cost, thus the cost of the slurry is lower；String of the present invention
Slurry is very suitable for GRC injections, and the bed of material consolidation formed in course of injection is fine and close, is flattened without human assistance, very great Cheng
Human cost is reduced on degree.
