Abstract
The invention discloses a waterproof sealed polyester by the modification of hydrophobic nano ZnO microspheres- nitrile rubber composite powder coating, wherein the powder coating compounds polyester resin with liquid nitrile rubber and silicone master batch for use, which effectively improves the appearance of shrinkage and crack on the coating when the hydroxyalkylamide is used as curing agent, and obtains powder coating with good adhesive force and sealing property, the prepared hydrophobic nano ZnO microspheres is the composite microsphere of good heat and chemical stability obtained from the coating treatment on nano zinc oxide with ethyecellulose, and the dispersibility is better through silane coupling agent surface modification. It significantly improves the usability of the powder coating, combining with other materials, the final finished powder coating is of the effect of fast film formation, strong adhesion, fast light, resistance to weathering, resistance to salinity, acid and alkali, hydrophobic densification etc., and usage experience and service life are effectively improved under outdoor environment.
Description
Technical field
The present invention relates to outdoor powder coating technology field, particularly relate to a kind of modified through dewatering nano ZnO microsphere
Waterproof sealing polyester-nitrile rubber composite powder coatings and preparation method thereof.
Background technology
Along with growth in the living standard, body-building game console material is as integrating the body-building multi-functional equipment with amusement little
The ground such as district, square is seen everywhere.Mostly these equipment itself are to be made up of metal material, and surface spraying coating is made, due to body-building
Equipment of travelling directly contacts human body, and mostly user is old man and child, and therefore the feature of environmental protection of coating is most important, and aqueous is coated with
Material extensively receives publicity as the coating that a kind of feature of environmental protection is higher, but the perishable metal of the water capacity, be not suitable on the metal material
Film, body-building apparatus is placed on outdoor more in addition, for a long time by illumination, rainwater, high temperature, cold and sweat, antibacterial etc. because of
The erosion of element, makes have more than is needed how long to fall paint and come off, affects attractive in appearance and experience, therefore its durability to coating
Also there is high requirement.
Powdery paints is the solid powdery coating of a kind of high-environmental, the most progressively replaces traditional solvent based coating, should
With increasingly receiving publicity.Wherein polyester powder coating has excellent weatherability, is referred to as Weather-resisting powder coating, can be by it
It is applied on body-building game console material, yet with the combined influence many factors of outdoor environment, it is still necessary to traditional polyester powder
End coating does further performance improvement, improves its service life." research of perfluoropolyether-modified polyester powder coating " literary composition
Be prepared for a kind of perfluoropolyether-modified polyester resin powder coating, the coating that this coating is formed have good weather-proof anticorrosion,
The effects such as hydrophobic anti-soil, but the adhesive force of this coating is not fully up to expectations, and peeling resistance is poor, in addition coating surface friction
Coefficient is on the low side, there is potential safety hazard, and production cost is higher during use, economical not, it is therefore desirable at its further modification
Reason, the product the most superior to obtain combination property.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of modified through dewatering nano ZnO microsphere
Waterproof sealing polyester-nitrile rubber composite powder coatings and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of waterproof sealing polyester-nitrile rubber composite powder coatings modified through dewatering nano ZnO microsphere, should
Powdery paints is made up of the raw material of following weight portion: polyester resin section 50-60, LNBR 10-15, dewatering nano oxygen
Change zinc microsphere 10-15, silicone master batch 4-6, hydroxyalkyl amide 3-5, pigment 5-15, zinc stearate 1-2, silane coupler kh560
0.4-0.5, vulcanizing agent PDM 0.1-0.2.
Described dewatering nano zinc oxide is prepared by the raw material of following weight portion: nano zine oxide 8-10, ethyl cellulose
4-5, ethyl acetate 15-20, dodecyl sodium sulfate 0.1-0.2, water 10-15, its preparation method is:
(1) first putting in water by dodecyl sodium sulfate, stirring adds nano zine oxide after being completely dissolved to it, ultrasonic stirs
Mix mixing 40-50min, gained solution for standby；
(2) ethyl cellulose and ethyl acetate are hybridly prepared into solution, under stirring, are added dropwise over step subsequently
(1) material prepared, through pelleting centrifugation, washing after drying and get final product after continuing stirring mixing 30-40min after interpolation.
Described a kind of waterproof sealing polyester-nitrile rubber composite powder coatings through dewatering nano modified zinc oxide
Preparation method is:
(1) by standby after dewatering nano ZnO microsphere and silane coupler kh560 mixed grinding dispersion 20-30min；
(2) step (1) gained material is put in high speed mixer together with other each raw material it is uniformly mixed, subsequently
Material is sent in double screw extruder, extruding pelletization under the conditions of 105-110 DEG C, cooled, pulverize, sieve after and get final product.
The powdery paints of the present invention, by polyester resin and LNBR, the compounding use of silicone master batch, effectively improves
Shrinkage cavity that hydroxyalkyl amide occurs as coating during firming agent, cracking phenomena, it is thus achieved that there is good adhesion and sealing
The powdery paints of energy, the dewatering nano ZnO microsphere of preparation is, with ethyl cellulose, nano zine oxide is carried out cladding process,
Obtaining and have the complex microsphere of good thermal stability and chemical stability, after silane coupler surface modification, dispersibility is more for it
Good, significantly improve the serviceability of this powdery paints, in conjunction with other raw material, the final powdery paints prepared has film forming
Hurry up, adhere to the effects such as weatherable strong, fast light, the antiacid alkali of anti-salt, hydrophobic densification, out of doors experience and use longevity in environment
Life all effectively improves.
