Description
Technical field
The invention discloses a kind of preparation methods of the special adhesive of flexible face brick, belong to adhesive technical field.
Background technology
As modern people's living standard improves, the improvement of living conditions is advocated in country under building energy conservation emission reduction policy
It needs and a kind of meeting low-carbon environment-friendly, multi-functional, decorative strong building and ornament materials to replace original traditional organic dress
The high energy consumptions material such as plaque, glass curtain wall, coating, ceramic tile and stone material.
Multi-use architecture energy-saving flexible ornament materials building decorations patch（Porcelain tendre）It is to be modified common inorganic powder, then to be modified nothing
Machine powder is made of main component, has not only remained the resistance to ag(e)ing of inorganic material, but also the flexibility with organic material.Porcelain tendre, and
Non-real porcelain, nor ceramic tile, it is a kind of novel building and ornament materials.According to《Porcelain tendre building decoration engineering technology is advised
Journey》It explains：By modified soil（MCM）For primary raw material, with special temperature control moulding system molding, baking, cross-linking radiation and
At one kind have building decoration plane materiel flexible.At the beginning of birth, it has the appearance of ceramic tile, therefore is commonly called as soft
Porcelain with the development of technology, can develop to imitative stone material, leather texture imitation, imitation wood etc. later, and every to imagine, porcelain tendre is all
It can be achieved.
The coefficient of thermal expansion of different materials is different, and on combined two kinds of material interfaces, the sufficiently large temperature difference can
Larger shear stress can be caused to interface, influence the fastness of material combination.It, on the one hand should be as possible to reduce warm and humid shear stress
Selection line the is swollen small combination of materials of difference of coefficients, another aspect, it is also necessary to consider the flexibility index of binding material.Porcelain tendre is flexible
Face brick is starched using dedicated bonding, and main component is mud powder and acrylic emulsions.But porcelain tendre adhesive traditional at present
There is a problem of that flexibility and adhesion strength are bad, therefore also needs to study it.
Invention content
The present invention solves the technical problem of：It is asked for traditional soft porcelain adhesive flexibility and adhesion strength are bad
Topic, provides a kind of preparation method of the special adhesive of flexible face brick.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）It counts in parts by weight, takes 20~30 parts of polycaprolactone glycols successively, 40~50 parts of trimethylhexane diisocyanates, 2

Amine, 60~80 parts of deionized waters, polycaprolactone glycol and trimethylhexane diisocyanate constant temperature are stirred to react, and cooling adds
Enter N-Methyl pyrrolidone to be stirred to react, dihydromethyl propionic acid, trimethylolpropane, ethylene glycol, butanediol, cottonseed is then added
Oil, dibutyl tin laurate constant temperature are stirred to react, and are subsequently added into acrylic acid hydrocarbon ethyl ester and are stirred to react, and triethylene is added in cooling
Tetramine and deionized water are stirred to get modified polyurethane emulsion；
（2）It counts in parts by weight, takes 20~30 parts of polyacrylamide resins, 60~80 parts of deionized waters, 8~10 parts of surfaces successively
Activating agent, 5~10 parts of chromium trichloride solution, polyacrylamide resin and ion water termostat are stirred, and add surface work
Property agent and chromium trichloride solution constant temperature are stirred to get modified emulsion；
（3）It counts in parts by weight, by 60~80 parts of modified polyurethane emulsions, 80~100 parts of modified emulsions, 30~40 parts of modifications are filled out
Material, 8~10 parts of silane coupling agents and 8~10 parts of carbomers are stirred to get the special adhesive of flexible face brick.
Step（2）The surfactant is Tween-85, any one in Si Pan -60 or Si Pan -80.
Step（3）The preparation process of the modified filler is：By sepiolite ball mill grinding, sieving obtains sepiolite powder, will be extra large
Afrodite powder and hydrochloric acid in mass ratio 1：50~1：100 are stirred reaction, filter, washing, dry to get modified filler.
Step（3）The silane coupling agent is silane resin acceptor kh-550, silane coupling agent KH-560 or silane coupling agent
Any one in KH-570.
Step（3）The carbomer is carbomer 930, any one in carbomer 937 or Acritamer 940.
The beneficial effects of the invention are as follows：
（1）The present invention contains a large amount of double bond and carboxyl-functional by adding modified polyurethane emulsion in cotton seed oil minor structure
Group, after being added in polyurethane resin systems so that polyurethane resin molecular chain-end double bond content increases, and resin is in solidification process
In, terminal double bond reaction compartment steric hindrance is smaller, while with the presence of carboxyl isopolarity functional group, emulsion particle cohesive force can be made to obtain
Enhancing further promotes product adhesion strength, meanwhile, the aliphatic long-chain structure in cottonseed oil molecule can effectively promote system
Flexibility and shock resistance；
（2）The present invention is by adding modified emulsion, and first, during emulsion modified, trivalent chromic ion promotes as crosslinking agent
Micro- crosslinking occurs inside system, forms micro- cross-linked network, during storage, due to the presence of micro- cross-linking system, plays good
Good thickening effect, avoids system from being separated, the stability of emulsion system is effectively ensured, to effectively promote the storage of product
Stability is deposited, secondly, in use, since trivalent chromic ion cross-linking system gel-formation power is stronger, is added in system, makes
Between colloid cohesive force increase, to promote the adhesion strength of product, again, when the external world is there are when the larger temperature difference, the larger temperature difference
So that gluing interface goes out there are larger shear stress, since trivalent chromic ion cross-linking system has good viscoplasticity, when
There are when shear stress effect, system can be restored system automatically, and shear stress is avoided to cause harmful effect to cross-linking system, to effectively
Promote the adhesion strength of product.
