Foamed board, panel be plastic splint or aluminium alloy plate, this sheet material for compression plate, with good water-proof effect, quality
Gently, it is indeformable, the advantages of long service life, but this sheet material high cost, fire protecting performance is poor, and being still unable to spread should
With.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of waterproof, fire prevention, insulation, low production cost, uses the longevity
Order environment-friendly waterproof sheet material long and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of environment-friendly waterproof sheet material, including XPS foamed boards, the both sides of the XPS foamed boards are provided with adhesive layer, the adhesive layer
Outside be equipped with clathrum, the outer application of the clathrum has coating.
The clathrum is glass fiber mesh.
The gross thickness of the adhesive layer and coating is 0.5mm to 5mm.
Furthermore, its step of the preparation method of the environment-friendly waterproof sheet material is as follows:
(a), cutting:XPS foamed boards are placed in cutting machine, cutting forms the sheet material of suitable dimension;
(b), for the first time spray:Adhesive layer is formed in the front spray adhesive mortar of sheet material;
(c), lapping:Clathrum is laid on adhesive layer;
(d), second spray:Covering mortar is sprayed on clathrum and forms coating;
(e), strike off:Coating is struck off using scraper and hairbrush, smooths its surface;
(f), baking:Toasted during workpiece is sent into baking box, harden adhesive layer and coating;
(g), repeat the above steps(b)Arrive(f), first time spray, lapping are carried out to the back side of sheet material, are sprayed for the second time, are struck off
And baking;
(h), trimming:Sheet material is placed on cutting machine, the edge to sheet material cuts, makes its edge concordant, while in sheet material
Side wall form the step of L-type.
The step(f)In dry temperature between 40-90 DEG C.
The adhesive mortar is the mixture of quartz sand, cement, adhesive and water, wherein, quartz sand, cement, adhesive
Weight ratio with water is:20:40:4:15, the particle diameter of quartz sand is less than 0.5mm.
The covering mortar is the mixture of quartz sand, cement, adhesive and water, wherein, quartz sand, cement, adhesive
Weight ratio with water is:15:45:4:15, the particle diameter of quartz sand is less than 0.3mm.
The beneficial effects of the invention are as follows:Environment-friendly waterproof sheet material of the invention with XPS foamed boards as sandwich layer, and the two of sandwich layer
Side sets adhesive layer, clathrum and coating, and clathrum is glass fiber mesh, and the composition of adhesive layer and coating is mainly cement
Mortar, with lightweight, intensity is high, the advantages of waterproof, fire prevention, insulation, low production cost, long service life, can extensive use
In the finishing such as metope, ground, blank of the XPS foamed boards in finishing field is filled up, Novel environment-friendlymaterial material can have been promoted in building
The popularization and application of industry.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is structure decomposition figure of the invention;
Fig. 2 is enlarged diagram at A in Fig. 1.
Specific embodiment
Reference picture 1, Fig. 2, a kind of environment-friendly waterproof sheet material, including XPS(Extrusion molding polystyrene polyfoam)Foamed board 1, XPS
The both sides of foamed board 1 are provided with adhesive layer 2, and the outside of adhesive layer 2 is equipped with clathrum 3, and the outer application of clathrum 3 has covering
Layer 4, in the present embodiment, clathrum 3 is glass fiber mesh, and the composition of adhesive layer 2 and coating 4 is mainly cement mortar, glues
The gross thickness for closing layer 2 and coating 4 is 0.5mm to 5mm, and with lightweight, intensity is high, waterproof, fire prevention, insulation, production cost
The advantages of low, long service life, the finishing such as metope, ground is can be widely applied to, filled up XPS foamed boards 1 in finishing field
Blank, can promote Novel environment-friendlymaterial material in the popularization and application of building trade.
In the present embodiment, the preparation method of the environment-friendly waterproof sheet material, its step is as follows:
(a), cutting:XPS foamed boards 1 are placed in cutting machine, cutting forms the sheet material of suitable dimension;
(b), for the first time spray:Adhesive layer 2 is formed in the front spray adhesive mortar of sheet material;
(c), lapping:Glass fiber mesh is laid on adhesive layer 2;
(d), second spray:Covering mortar is sprayed on clathrum 3 and forms coating 4;
(e), strike off:Coating 4 is struck off using scraper and hairbrush, smooths its surface;
(f), baking:Toasted during workpiece is sent into baking box, dried temperature between 40-90 DEG C, made adhesive layer 2 and covering
Layer 4 is hardened;
(g), repeat the above steps(b)Arrive(f), first time spray, lapping are carried out to the back side of sheet material, are sprayed for the second time, are struck off
And baking;
(h), trimming:Sheet material is placed on cutting machine, the edge to sheet material cuts, makes its edge concordant, while in sheet material
Side wall form the step of L-type, be easily installed.
Furthermore, adhesive mortar is the mixture of quartz sand, cement, adhesive and water, wherein, quartz sand, water
The weight ratio of mud, adhesive and water is:20:40:4:15, the particle diameter of quartz sand is less than 0.5mm.Covering mortar is quartz sand, water
The mixture of mud, adhesive and water, wherein, the weight ratio of quartz sand, cement, adhesive and water is:15:45:4:15, quartz sand
Particle diameter be less than 0.3mm.
The preparation method of the adhesive mortar or covering mortar is as follows:
(i), water poured into one more than 100 liters of bulk container metal bucket, and the bulk container metal bucket be placed in high speed dispersor do
Mix leaf center to be stirred, mixing speed is 5000 ± 100r/min;
(j), by quartz sand and cement point 5 addition metal bucket containers, continue to stir;
(k), add adhesive, continue stir, mixing speed be 18000 ± 100r/min, mixing time is 10min;
(l), with concentration determination cup measurement slurry concentration, until after test concentrations reach 65 ± 5s/ glass, close dispersion machine, extraction
Qualified slurry is reached the standard grade and is used.
In the present embodiment, cement uses PO32.5R high-mark cements, adhesive to use 901 building glues or white glue with vinyl,
Solidification is very fast, adhesive strength is higher.
Implementation method above can not limit the protection domain of the invention, and the personnel of professional skill field are not departing from
In the case of the invention general idea, impartial modification and the change done still fall within the scope that the invention is covered
Within.
