Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of rose scent polyester powder coating and preparation method thereof.
Background technology
Powder coating is a kind of novel not containing solvent 100% solid powdery coating.There is solvent-free, pollution-free, recyclable, environmental protection, the saving energy and resource, reduce labor intensity and film physical strength high.Heat curable powder coating refers to using thermosetting resin as filmogen, and the solidifying agent having added crosslinking reaction can form insoluble not molten quality hard coat after heating.Thermosetting powder coating(s) because of the levelling property of its coating better, by force ornamental, and low-molecular-weight prepolymer is after solidification, and can form the macromole of cross-linked network, thus coating has better preservative property and mechanical property, therefore thermosetting powder coating(s) development is particularly rapid.
Pure polyester type powder paint, because having excellent weathering resistance, is commonly called Weather-resisting powder coating.Pure polyester type powder paint is widely used in the fields such as automobile, machinery, instrument and construction industry.Its shortcoming is that cross-linking density is lower, and the solidification value of needs is higher, lower to the sticking power of coated article.The existing weather-resistance powder coatings of China, still takes as the leading factor with polyester/TGIC, but its weathering resistance can not show a candle to fluorocarbon powder paint.But the fluorocarbon resin technology that China is used for powder coating is still immature, and extremely expensive from its price of external import.Therefore, the weather-resistance powder coatings of a kind of low cost of research and development is badly in need of, to meet the demand of demestic user.
" research of perfluoropolyether-modified polyester powder coating " one literary grace melting copolymerization method synthesize perfluoropolyether-modified vibrin, in polyester molecule chain, introduce the PFPE side chain of relative molecular mass about 3000.This literary composition is with TGIC(isocyanuric acid three-glycidyl ester) be solidifying agent, with the powder coating that this resin is made, not only have superpower preservative property and weathering resistance, and have good hydrophobicity, oleophobic property and automatically cleaning effect, cost is low is widely used in every field.
But the condition of cure of polyester/TGIC system is harsh: TGIC is poisonous, solidification value higher (>200 DEG C), set time longer (10-30min), higher solidification value makes its energy consumption high, baking time is long, directly cause the production cycle elongated, labour productivity can not get effective raising.Meanwhile, harsh condition of cure makes powder coating can only for heat-resisting metal substrate, is not suitable for the thermosensitive type grounds such as wooden, papery, plastics, seriously constrains the application of powder coating, need to carry out improving existing processing condition and method.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of rose scent polyester powder coating and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of rose scent polyester powder coating, is made up of the raw material of following weight part: vibrin 70-72, thermosetting acrylic resin 12-14, Stainless Steel Fibre 4-6, attapulgite 18-22, zinc naphthenate 0.2-0.4, nano titanium oxide 1.9-2.3, Flos Rosae Rugosae quintessence oil 0.1-0.3, Tyox B 2.3-2.6, polyvinyl alcohol 1.5-1.7, beta-hydroxy alkylamide 4.8-5.5, pigment 7.5-8.5.
The making method of described a kind of rose scent polyester powder coating, comprises the following steps:
(1) by thermosetting acrylic resin, Tyox B in 105-125 DEG C of stirring and evenly mixing, be warming up to 160-170 DEG C, 200-300 rev/min of dispersed with stirring 4-6 minute, is cooled to room temperature and adds zinc naphthenate ball milling 1-2 hour, obtain modified heat convertible acrylic resin;
(2) attapulgite being scattered in the mass concentration be mixed with by polyvinyl alcohol is obtain suspension in the aqueous solution of 5-8%, suspension is placed in 80-90 DEG C of water bath with thermostatic control and leaves standstill 3-5 hour, add nano titanium oxide, Stainless Steel Fibre stirs and ultrasonic disperse grinds 30-40 minute, dropwise drip Flos Rosae Rugosae quintessence oil, within 30-50 minute, drip off, continue insulation 30-50 minute, adjust ph 7-8, be cooled to normal temperature rapidly, filtration under diminished pressure, washing are also dry;
(3) vibrin is dropped in high mixer, add step (1), step (2) material and other remaining component stirring and evenly mixings, melt extrude through twin screw extruder, compressing tablet, air-cooled, abrasive dust, cross 160-180 mesh sieve, to obtain final product.
Advantage of the present invention is: the present invention adopts beta-hydroxy alkylamide to substitute TGIC solidifying agent, toxicity is little and solidification value is low, energy-conserving and environment-protective, by attapulgite, nano titanium oxide, its dispersiveness in vibrin and interracial contact is improve after Stainless Steel Fibre graft modification, improve coatability energy and the self-cleaning performance of coating, resistance to soiling improves, add again modified thermosetting acrylic resin, production technique simple operations is easy, optimize the mechanical property of powder coating, obtained powder coating intensity is high has excellent weathering resistance and permanent rose fragrance, product environmental protection simultaneously, production process is simple, production cost is low, and store, convenient transportation, be applicable to very much carrying out scale operation to apply.
