Description
Technical field
The present invention relates to a kind of back cover coating of textile fabric more particularly to a kind of back cover paintings containing radial block polymer
Layer.
Background technique
The weaving dry goods product of printing gives graceful eye impressions, the brightness of perfect color rendering and high glaze,
Have become the decoration ornaments in building room, the raising with people to art work quality requirements, weaving of the consumer to printing
Dry goods product is put forward higher requirements.However, influencing beauty since the fabric of textile cloth is there are the villus of plant fiber and flaw point
Sense, and fabric latitude and longitude are made of countless fine sands, structure is sparse, and quality is loose, therefore can not be in textile cloth base fabric directly
It is coated with ink-absorbed coated layer.Currently, the measure generally taken are as follows: be first coated with back cover coating in textile cloth, then applied on back cover coating
Cloth ink-absorbed coated layer.And existing back cover coating is easy to appear sedimentation when coating stores, and using the time is short and material leakage, cohesive force
The problems such as poor, these factors influence the coating efficiency and effect of woven fabric base.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of back cover coatings for textile cloth, are hiding
Drop cloth base flaw, guarantee cloth base not bleed while improve cloth base cohesive force and adhesive force.
The present invention to achieve the above object, using following technical scheme:
A kind of textile fabric back cover coating containing radial block polymer, is prepared from the following components: filler, resin, star
Shape block polymer, dispersing agent and defoaming agent.
Filler of the present invention is mixed by kaolin and titanium dioxide, and mixed proportion is 1:1 to 3:1.
A kind of heretofore described textile fabric back cover coating containing radial block polymer, according to the mass fraction, including
60-100 parts of filler, 10-40 parts of resin, 0.1-0.3 parts of radial block polymer, 0.1-0.5 parts of dispersing agent, defoaming agent 0.1-
0.5 part.
The structural formula of heretofore described radial block polymer is as follows:
Wherein the average degree of polymerization m value of PCL block is 5-15.
Heretofore described resin is polyvinyl alcohol, the mixture of one or more of organosilicon acrylic resin and polyurethane.
The viscosity of back cover coating is 1000-8000 mPas in the present invention.
A kind of heretofore described textile fabric back cover coating containing radial block polymer the preparation method is as follows:
By kaolin, titanium dioxide and dispersing agent are added in deionized water, with the Rate Dispersion 40min of 3000r/min, then
Sequentially add resin, defoaming agent and radial block polymer.30min, 260 mesh filter screens are stirred with the speed of 300-500r/min
After filtering.
Woven fabric base is fixed on small-sized needle plate, back cover coating is coated on woven fabric base with scraper, is put into baking oven
Middle drying, 80 DEG C -100 DEG C of drying temperature.
The present invention has the advantage that the prior art
Radial block polymer will be added in back cover coating, since the PEO segment of radial block polymer has parent
Aqueous, PCL segment has hydrophobicity, micellar structure is formed in water-based system, the micella that radial block polymer is formed is compared with line
Shape polymer has better inclusiveness, is suspended in filler particles preferably in coating, paint stability is improved, to improve painting
The storage time of material.Radial block polymer forms the trend of molecular entanglement compared with the line polymer of identical molecular weight
It is smaller, to be more soluble in existing back cover coating system, improve the compatibility of coating.The support arm structure of radial block polymer
On functional group and coating system in functional group interaction, improve crosslinking after film forming, make woven fabric base not material leakage, together
The cohesive force and adhesive force of Shi Tigao coating.
