Description
Technical field
The present invention relates to wear-resistant paint fields, and in particular to improved silica and its application on wear-resistant paint.
Background technique
From nineteen thirty-seven Germany Otto., professor Bayer is for the first time since synthesis of polyurethane (PU) resin, because it is with excellent
Chemical property and physical mechanical property have been widely used in chemical field.Polyurethane coating is because with excellent wear-resisting
Property, flexibility, durability, anti-corrosive properties and insulating properties and be widely used in not standby petrochemical industry, ocean, ship, electromechanics, vehicle, spinning
It knits, the fields such as leather, timber, plastics, building.
But on ahead market it is popular it is most of be solvent borne polyurethane coating, contain a large amount of organic solvent and one
Quantitative free isocyanate influences the health and living environment of people.With various countries' environmental regulation to the limitation of VOC with
And the attention to environmental protection, aqueous polyurethane have obtained faster development, have obtained extensively in fields such as fabric, leather, adhesives
General application, just gradually substitutes solvent borne polyurethane.With advances in technology with the strict control of VOC content and people's environmental protection and
The raising of health perception, aqueous PU will become an important developing direction.
Currently, China's research and development aqueous polyurethane is made slow progress, and up to the present, industrialized aqueous polyurethane kind
Less, yield is small, is essentially all the pure polyaminoester emulsion of some aromatic types.Film forming, mechanicalness and the water resistance of product
It is poor, it is mainly used for the leather finishing agent and fabric treating of general performance, is difficult to high performance leather, fabric.
Currently, this sends out a kind of, improved silica is applied in wear-resistant paint, uniform by using brushing or spraying method
Coat and be solidificated in fabric, leather surface, good film-forming property, adhesive force are strong, wear-resisting property is good.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the present invention provides a kind of improved silica, wear-resistant paint and answer
With.

55-75 DEG C of stirring 50-70min is then heated to, zinc chloride is added in 35-40 DEG C of stirring 2-5h, centrifuge separation, abandoning supernatant will
Precipitating drying to get.
Another technical solution, a kind of improved silica, the improved silica are prepared by the following method: by 5-15g
It is the ammonium hydroxide tune for being 15-25% with mass fraction in 60-80% ethanol water that 100-150g volume fraction, which is added, in silica
PH to 9-11 is saved, then ultrasonic disperse 20-40min, it is 200- that 10-20g gamma-mercaptopropyltriethoxysilane, which is added, with revolving speed
400r/min stirs 10-30min, and then heating to 55-75 DEG C with revolving speed is that 200-400r/min stirs 50-70min, and chlorine is added
Change zinc temperature be 35-40 DEG C with revolving speed be 200-400r/min stirring 2-5h, be centrifugated 20- through 5000-8000r/min
40min, abandon supernatant will precipitating drying to get.
Preferably, the temperature of the drying is 900-110 DEG C, time 20-30h.
Preferably, the molar ratio of the zinc chloride and silica is (1-2.5): 1.
Application the invention also discloses above-mentioned improved silica and its on wear-resistant paint.
Concrete application is as follows:
A kind of wear-resistant paint is prepared by following raw materials in parts by weight: 60-70 parts of aqueous polyurethane emulsion, water
Property 20-30 parts of acrylic emulsion, 3-8 parts above-mentioned of improved silica, 0.5-1.5 parts of emulsifying dispersant, quaternary ammonium salt addition
1-2 parts of agent, 20-40 parts of water.Above-mentioned each raw material is uniformly mixed to get wear-resistant paint is arrived.
The emulsifying dispersant is nonylphenol polyoxyethylene ether.
The quaternary ammonium salt additive is poly- 3- acryloyl chloro hydroxypropyltrimonium chloride, amphiphilic O- ethoxy shell is poly-
Or mixtures thereof one of sugared lauryl ammonium chloride.Preferably, the quaternary ammonium salt additive is poly- 3- acryloyl chloro
Hydroxypropyltrimonium chloride, amphiphilic O- hydroxyethyl chitosan lauryl ammonium chloride are 1:(1.5-2.5 in mass ratio) it is mixed
Close object.
The beneficial effects of the present invention are:
Improved silica of the invention is applied in wear-resistant paint, can be obviously improved the wear-resisting property of wear-resistant paint,
It can also be obviously improved the adhesive force of wear-resistant paint simultaneously, the wear-resistant paint of the invention containing improved silica is applied to
