Description
Technical field
The invention belongs to safety and environmental protection pigment and technical field of dye, it is related to a kind of safe environment protection type lithotome waterproof to resist
Alkali gum and preparation method thereof.
Background technology
Lithotome refers to mined from natural rock mass, and the processed material into block or tabular, building decoration
In commonly use lithotome mainly have two kinds of granite and marble.The trailing of lithotome is mainly dry-hanging method and wet combining
Method.Wherein, dry-hanging method takes up room greatly, high cost, applies in general to the larger office business hall of exterior wall or space；And wet combining
Method is mainly used in the upholstery of various buildings, and it has two big subject matters：One be as binding agent gum with it is natural
Adhesion strength between stone material is not enough, easily produces hollowing phenomenon；Two is easily to produce efflorescence, causes stone material to change colour, drop
Low aesthetic property.Efflorescence produce main cause be：Lithotome crystallization is relatively thick, there is what many was invisible to the naked eye
The materials such as capillary, easily infiltration, water, alkali, salt in gum can produce capillarity, and appearance is infiltrated into by lithotome inner side
Face or joint filling falsity, and then produce efflorescence.
In order to avoid there is efflorescence, for the stone material (ecru, white etc.) of light color, existing solution is to adopt
Bonded with white stone material gum, be also the color of white stone material gum even if so there is bleeding, be not in obvious
Aberration.But there are the following problems for the method：First, cure the symptoms, not the disease, could not fundamentally avoid the generation of efflorescence, and only fit
For light stone material, poor universality；2nd, white stone material gum is that, using white cement as base-material, white cement is strong under equal conditions
Degree is weaker than ash concrete, in addition the back side of stone material all smoothers, and hollowing phenomenon can just occur unavoidably；3rd, because stone material gum does not have
There is GB, and the lithotome performance that major producers process differs so that the actual effect of the method is difficult to be guaranteed.
At present, the bi-component that stone material gum on the market is mostly compounded using acrylic emulsion and ordinary cement is carried on the back
Glue, because cement has alkalescence very high in itself, so it is difficult to the white China's problem of the accumulation of salt in the surface soil for fundamentally solving lithotome, reduces
The application value of lithotome.
The content of the invention
It is high that the purpose of the present invention provides a kind of adhesion strength for the defect for overcoming above-mentioned prior art to exist
Safe environment protection type lithotome water-proof alkali-resistant gum and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of safe environment protection type lithotome water-proof alkali-resistant gum, the gum includes following components and weight portion content：Liquid
4-6 parts of body mixture, powder mixture 4-6 parts, described liquid mixture includes following components and weight portion content：Acrylic acid
It is emulsion 380-420 parts, lithium silicate aqueous solution 95-105 parts, bactericide 1-3 parts, defoamer 1-3 parts and water 450-550 parts, described
Powder mixture include following components and weight portion content：Kaolin 430-480 parts, heavy calcium carbonate 280-320 parts, snow
Grey powder 230-270 parts, water reducer 1-3 parts and cellulose 1-3 parts.
Described acrylic emulsion is commercially available Ahmedabad richness RS-2608.By the acrylic emulsion with 100 μm of paint film spreaders
Molding on a glass, through 50 DEG C of dryings 1 hour after, then soaked 96 hours, without there is the anomalies, table such as whiting or micro- indigo plant
Bright its has good water resistance.
In described lithium silicate aqueous solution, the mass percent of lithium metasilicate is 35-45%, and the modulus of lithium metasilicate is 4-8.Water
The cohesive force of glass is strong, is a kind of conventional adhesive of building field.Lithium metasilicate is the one kind in waterglass, in odorless, tasteless
Transparence liquid, with from dryness, after moisture evaporation in solution, can generate a kind of water insoluble dry film, thus silicic acid
The water resistance of lithium is very excellent.Further, since the radius of lithium ion is smaller so that the penetrating power of lithium ion is very strong, energy
In enough infiltrating into cement base wall, and reacted with the calcium hydroxide in cement base wall, generate thick calcium silicates, silicon
Sour calcium as adhesive, can further improve the adhesive property of gum, enable lithotome even closer in combination with wall,
Avoid producing hollowing phenomenon.
Described bactericide is commercially available KATHON LXE.
Described defoamer is commercially available NOPCO NXZ.
The mesh number of described heavy calcium carbonate is 500-600 mesh.
The mesh number of described snowflake white powder is 80-120 mesh.
Described water reducer is commercially available BASF F-10.
Described cellulose is the hydroxypropyl methyl cellulose of the viscosity of 3-5 ten thousand.
A kind of preparation method of safe environment protection type lithotome water-proof alkali-resistant gum, the method specifically includes following steps：
(1) preparation of liquid mixture：Acrylic emulsion and lithium silicate aqueous solution are added into water respectively, is stirred
Afterwards, bactericide, defoamer are separately added into, and 5-10min is stirred under 800-1000r/min, that is, described liquid mixing is obtained
Thing；
(2) preparation of gum：Under the mixer rotating speed of 500-800r/min respectively by kaolin, heavy calcium carbonate,
Snowflake white powder, water reducer and cellulose are added into liquid mixture, and stir 10-20min under 400-700r/min, that is, make
Obtain described safe environment protection type lithotome water-proof alkali-resistant gum.
Compared with prior art, the invention has the characteristics that：
1) lithium silicate aqueous solution and acrylic emulsion are compounded, not only makes gum that there is high bond strength and water-fast
Property, simultaneously because lithium metasilicate can react with the calcium hydroxide in cement base wall, acted on certain alkali resistant, thus
White China, the accumulation of salt in the surface soil, the water spots phenomenon of lithotome can be fundamentally solved, the application value of lithotome is improve；
2) using kaolin, heavy calcium carbonate and snowflake white powder as powder, with existing acrylic emulsion and commonly
The bi-component gum of cement compounding is compared, and not only avoid the overbasic cement of introducing, reduces the generation of accumulation of salt in the surface soil phenomenon
Rate, while having faster rate of setting, it is to avoid unexpectedly injured in duration of coagulation because cement setting time is long,
Cause the problem of intensity decreases, thus it is more safe and reliable；
3) harmful toxic matter and high pollution material are free of in component, and preparation method is simple, process conditions are gentle, safety collar
Protect.
