Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of aging resistant coating.
Background technology
Coating act as decorating and protects, protect by the surface of painting jewelry, prevent from extraneous light, oxygen, chemical substance,
The erosion of solvent etc., improves the service life for being applied thing, paint finishing material surface, changes its color, decorative pattern, gloss, matter
Sense etc., improves the aesthetic value of object.Building coating mode classification is various, and row such as divide inner-outer wall, ground and top by use environment
Canopy coating；By the organic and inorganic and organic-inorganic hybrid coatings of main film forming substance point；Divide water by the state of main film forming substance
Dissolubility, type of latex type and solvent borne powder-type；Divide planomural shape, sand wall-like and three-dimensional pattern shape according to decoration functions；By specific function
Divide fire prevention, waterproof, mould proof and anti-condensation etc..In existing decoration of exterior wall protects technique, people are in order to protect decoration of exterior wall, and one
As water-repellent paint is all coated on exterior wall.However, existing common exterior wall waterproofing coating on the market, its product quality are irregular not
Together, the short time is upper after coating or has preferable waterproof effect.But as the time increases, conventional coating just occurs
Whiting, jaundice, emetine phenomenon, the generally existing anti-aging phase is short, and dirty dirt, ink cannot clean, and moisture-proof, water-fast, washing fastness is poor
The shortcomings of, it is short in outdoor buildings top surface service life, therefore some products are only limitted to indoor use, and due to its raw material mostly
Using new material, cause production cost higher.More or less there are some such as easy to aging, peelings, easy to fall off, meeting for they
Discoloration, weatherability be poor, poisonous has the defects of taste, construction is inconvenient.Moreover, most this coating, as usage time increases,
Foaming phenomena can also be produced so that paint film surface is uneven, influences the slickness of paint film, and then accumulates dust, and causes
Overall appearance effect day, condition was poorer.
The content of the invention
The purpose of the present invention is for it is existing the problem of, there is provided a kind of aging resistant coating.
The present invention is achieved by the following technical solutions：
A kind of aging resistant coating, is made of following component by weight：Lignin modification styrene-acrylic emulsion 120-130, bentonite
10-12, polyvinyl acetate 3-6, ethanedioic acid tetraacethyl disodium 2.5-3.5, hollow beads 4-6, hydroxyethyl cellulose 6-12, PE
Wax 2-5, coupling agent 1.3-1.8, rosin glycerides 5-12, filler 12-15, deionized water 75-80.
Further, the lignin modification styrene-acrylic emulsion preparation method is：
（1）Lignin is pressed into 55g：The ratio of 300mL is dissolved in the sodium carbonate liquor that mass fraction is 10%, is heated to 60 DEG C, with
200r/min rotating speeds stir 40min, then add the epoxychloropropane of lignin quality 0.5%, continue to stir 30min, then use
The phosphoric acid solution that mass fraction is 10% adjusts pH value of solution to 3.2, adjusts the temperature to 88 DEG C, it is small to stir 2 with 500r/min rotating speeds
When, then filtered, drying to constant weight, obtains modified lignin resin；
（2）Modified lignin resin and styrene-acrylic emulsion are pressed into 35g：80 DEG C are heated to after the ratio uniform mixing of 550mL, with 1200r/
When min rotating speeds stirring 2 is small, the ammonium persulfate of styrene-acrylic emulsion quality 0.15% is then added, 65 DEG C is adjusted the temperature to, continues to stir
1.5 it is small when, to obtain the final product.
Further, the lignin is extracted from paulownia wood and obtained.
Further, the styrene-acrylic emulsion solids content 44%, viscosity 280mPas, level of residual monomers 0.5%, pH value
8.3。
Further, the bentonite is sodium bentonite.
Further, the coupling agent is organo silane coupling agent.
Further, the filler is glass fibre, calcium carbonate, zeolite powder by 2:1:1 mass ratio mixes.
The present invention has the following advantages compared with prior art：Aging resistant coating prepared by the present invention, with lignin modification benzene
Acrylic emulsion is the main foundation component of coating, while cooperates with the effect of polyvinyl acetate so that the coating of preparation not only has
Good uniformity, meanwhile, there is good permeability and particle absorption activity, can mutually combine closely with construction material,
The adhesive force of film is greatly improved, is acted synergistically between lignin modification styrene-acrylic emulsion and filler, can effectively be caused
The consistency of film is significantly improved, and stable network structure is formed between lignin modification styrene-acrylic emulsion and filler, Gu
After change, the hardness of film is greatly enhanced, so that the service life of film is effectively raised, simultaneously as wooden
Plain modifying cinepazid emulsion after film-forming, can significantly improve the intermolecular bond energy of film, can resist in coating system
The destruction of the factors such as light, heat, oxygen, hence it is evident that improve film resistance to ag(e)ing, greatly improve the service life of coating.
