Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention is clearer, below will be to the embodiment of the present invention in
Technical scheme be clearly and completely described, it is clear that described embodiment is a part of embodiment of the invention, rather than
Whole embodiments.Embodiment in based on the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.It should be noted that in situation about not conflicting
Under, the feature in embodiment and embodiment in the application mutually can be combined.
In order to ensure the adhesion strength of sheet material and being smoothed out for construction, the invention provides a kind of gypsum base lightweight plate
Timber-used binding agent, the composition of the gypsum base light weight board binding agent and its mass parts include：Calcium-magnesium powder 40-75 parts, desulfurization stone
Cream 24-50 parts, carboxymethylcellulose calcium 0.8-7.5 parts, retarder 0.2-2.5 parts, binder 0.1-0.5 parts.For example, should in preparation
During binding agent, calcium-magnesium powder 50-63 parts, desulfurated plaster 35-48 parts, carboxymethylcellulose calcium 1.5-6 parts, retarder 0.3- can be added
2 parts, binder 0.2-0.4 parts.In a typical embodiment, the gypsum base light weight board is included with binding agent：Calcium-magnesium powder
56 parts, 40 parts of desulfurated plaster, 3.5 parts of carboxymethylcellulose calcium, 0.8 part of retarder, 0.3 part of binder.
Wherein, calcium-magnesium powder is used as filler, can be increased small product size, be reduced production cost；Desulfurated plaster conduct
The base-material of binding agent is used；Carboxymethylcellulose calcium acts primarily as cementation as thickener；Tricalcium silicate and silicic acid can be selected
The mixture of dicalcium extends binding agent use time as retarder；Add a small amount of binder, can effectively strengthen binding agent
Cohesive force, while cause binding agent there is enough water-retaining propertys.
Desulfurated plaster internal structure is fine and close, with higher intensity and hardness, and with certain water resistance, its
Body can be used as binding agent with certain cementitiousness, with other binder phase ratios without compositions, more ring such as glue
Protect；After adding other fillers and stirring with water, the mutual interconnection of crystal forms network structure, makes gypsum slurry lose flowing
Property and condense so which produces higher adhesion strength.Wherein, carboxymethylcellulose calcium can improve the caking property of mixture
Can, and retarder can effectively extend the operable time of binding agent, binder improves the water-retaining property of binder mixtures.This
The raw material and filler adopted by bright binding agent is nontoxic composition, environment friendly and pollution-free, to environment and workmen, use
Personnel are harmless.
During using binding agent of the invention, after only need to be well mixed the raw material of above-mentioned weight portion under dry powder, press
Weight ratio according to powder and water is 1:0.29-0.45 is prepared, and stirs mixing, you can used.Using front cleaning body of wall
Surface, is bondd using empty patch method, i.e., fixed point smears binding agent, then pastes sheet material.Wherein, fixed point smears binding agent
Bonding point spacing can be 200mm-500mm, for example, it is possible to be set to 220mm, 300mm, 400mm etc..
Due to the present invention binding agent adhesion strength big, it is possible to bondd using empty patch method.This fixed point is smeared
The empty patch method of binding agent, compared with existing frequently-used full patch method, not only greatly reduces the applying amount of binding agent, saves bonding material
Material, and can effectively shorten the engineering time, improve efficiency of construction.
Specifically, the retarder in the present invention is mixture, including tricalcium silicate and dicalcium silicate.Wherein, tricalcium silicate
Weight allotment ratio with dicalcium silicate is 1:1～3:1.For example, it is possible to by tricalcium silicate and dicalcium silicate according to 2.2:1 weight
Amount carries out allotment retarder than mixing.
In the composition of above-mentioned binding agent, binder can select hydroxypropyl methyl cellulose ether, in order to improve binding agent
Water-retaining property.
In addition, present invention also offers a kind of preparation method of above-mentioned gypsum base light weight board binding agent, the preparation side
Method is comprised the following steps：
Calcium-magnesium powder is mixed with desulfurated plaster；
After adding carboxymethylcellulose calcium, retarder and binder, it is well mixed.
Wherein, retarder is the mixture of tricalcium silicate and dicalcium silicate, before above-mentioned adhesive is prepared, needs first to match somebody with somebody
Retarder processed.Therefore, above-mentioned preparation method also includes：
By tricalcium silicate and dicalcium silicate according to 1:1～3:1 weight ratio is well mixed, for example, according to 1.5:1 weight
Than tricalcium silicate is uniformly mixed with dicalcium silicate.
The preparation method of the binding agent that the present invention is provided is simple, quick, can at any time using, prepare at any time, easy to use.
The configuration proportion of its each component is different, and also there is nuance the binding agent setting time for preparing, but than traditional binding agent
Condensation is more quick, and is firmly bonded.Table 1 is listed in several specific embodiments, the binding agent prepared under different ratio
Several emphasis parameters.
The use parameter of binding agent prepared by 1 each composition different ratio of table
As shown in Table 1, the binding agent that each composition is prepared under different ratio, its also have trickle gap using parameter, this
Plant gap in actual use, be finely adjusted with reference to differences such as Practical Project material usage, use environment, engineering time limits.
Table 2 lists the use parameter of the binding agent adopted under several traditional cementi modes.
The use parameter of 2 several conventional binders of table
Contrast Tables 1 and 2 understands, when using glass cement, liquid glue etc. as alite paste, needs a few hours, even counts
After it, can condense completely, service life is shorter；And have in construction period and trial employment period meeting release formaldehyde, benzene etc.
Evil material.Although bonding gypsum can ensure that adhesion strength and setting time, price is higher, substantially increases and uses into
This.And the stickup of gypsum base light weight board is carried out using binding agent provided by the present invention, setting time can be greatly shortened, plus
Fast speed of application, the duration of effective guarantee engineering, and unharmful substance release, environment friendly and pollution-free, and into the cost being grouped into
Cheap, can be produced with effective control and use cost.
Descriptions above can combine individually or in every way enforcement, and these variants all exist
Within protection scope of the present invention.
