Description
Technical field
The present invention relates to glass lacquer technical fields, and in particular to a kind of novel environment-friendly water-based glass baking varnish of high adhesion force and
Preparation method.
Background technique
Glass is a kind of high rigidity, cleaning, material nontoxic, corrosion-resistant resistance to ag(e)ing is splendid, has been widely used in
The fields such as building decoration, household life product.The glass industry in the present age, in order to improve glassware (such as glass apparatus, polychromy
Glassware and eyeglass etc.) appearance, improve decorative effect, manufacturer is often used glass coating or ink is painted on glass table
Face.In recent years, water paint is because organic substance release content (VOC) is low, have good workability, its paint film has better uvioresistant
The advantages that beta radiation performance, color change is small, long service life, starts to be applied in glass coating.And water paint and solvent
The fundamental difference of type coating is non-organic solvent using water as solvent.Therefore it applies at glass lacquer field when water paint,
Be film-forming resin since waterborne glass coatings mostly use greatly water-based acrylic resin, and glass surface is smooth and surface free energy compared with
Low, common water-based acrylic resin is poor to the adhesive force of glass, and paint layer is easy to fall off.In addition, water paint is to glass base
The wetability of material is bad, and when viscosity of the coating is relatively low or paint film applies blocked up, paint film easily flows downward, and causes lower edge and bottom
The defects of face is blocked up and uneven.
Summary of the invention
Present invention aim to address existing technical deficiencies, provide a kind of novel environment friendly, not only high adhesion force, and soak
The stronger Water-based glass baking paints of comprehensive performances such as property, water-fast weatherability；The present invention also provides the preparation sides of the Water-based glass baking paint
Method.
The technical scheme adopted by the invention is that: a kind of novel environment-friendly water-based glass baking varnish, including by following weight proportion
Component be made:
A kind of novel environment-friendly water-based glass baking varnish, the preferred weight proportion of component are as follows:
Preferably, the organosilicon modified crylic acid resin is the silane-modified acrylic resin of epoxyhydrocarbyl or methyl-prop
The silane-modified acrylic resin of alkene acyloxyalkyl group.
Preferably, the waterborne polyurethane resin is hexamethoxymethyl melamine formaldehyde resin or methyl-etherified melamine
Amine-formaldehyde resins.
Preferably, the organosilan adhesion promoter is γ-(2,3 glycidoxy) propyl trimethoxy silicon
Alkane.
Preferably, the mill base is the mixture of pigment, dispersing agent and water.Pigment, dispersing agent and the water of the mill base
Mixed proportion is (3-5): 1:(5-10)
Preferably, the defoaming agent is amino-polyether organic silicon defoamer, polyethergpolysiloxane defoaming agent, polyethers
One kind of organic silicon defoamer.Amino-polyether organic silicon defoamer has a degree of heat-resisting, strong alkali-acid resistance performance；Polyethers
Graft polysiloxane defoaming agent foam time is short, while having stronger strong alkali-acid resistance performance, even if in harsh conditions (i.e. 90
DEG C, highly acid or strong basicity) under still have more excellent performance；Polyether silicones defoaming agent is by polyethers and passing through of organosilicon
What the form of key was formed by connecting, it combines the excellent performance of two kinds of defoaming agents of polyethers and silicone oil, and antifoam performance is more preferable.
A kind of preparation method of novel environment-friendly water-based glass baking varnish described above, comprising the following steps:
A) preparation of mill base: by pigment: dispersing agent: water mixing=(3-5): 1:(5-10) weigh raw material, first Jiang Shui and point
Powder stirs evenly, and adds pigment, and setting revolving speed is 2000-3000r/min, grinding distribution 20-30min.Then fineness is scraped,
Fineness≤10 μm are controlled, it is spare that mill base is made；
B) formula content of starting materials, organosilicon modified crylic acid resin, water-based hydroxyl acrylic acid are weighed according to claims 1 or 2
Resin, waterborne polyurethane resin, wetting agent, 50% defoaming agent sequentially add in mixing plant, in the revolving speed of 300-600r/min
Under, 15min is stirred in advance；
C) under the revolving speed of 500r/min, be added organosilan adhesion promoter, cosolvent, levelling agent, pH adjusting agent,
The defoaming agent of mill base, water and residue 50% continues stirring to 15-20min to being uniformly mixed, adjusts required viscosity to get new
Type ring water-retaining property glass baking varnish.
A kind of application method of novel environment-friendly water-based glass baking varnish described above, comprising the following steps:
A) ground is handled: being used dehydrated alcohol as solvent, is wiped surface of bottom material, removes surface floating dust and grease stain；
B) prepared by paint film: preparing paint film using the method brushed or sprayed, film thickness controls in 15-20 μm；
C) film curing: present 50 DEG C of preheatings 5-10min, then 30min is toasted at 80 DEG C.
Compared with the prior art, the present invention has the following advantages:
(1) novel environment-friendly water-based glass baking varnish of the invention, uses organosilicon modified crylic acid resin for film-forming resin, benefit
It is connected with the alkyl side of acrylic resin side-chain radical and organosilan, and organosilan is by hydrolyzing to form silanol, and glass
Glass surface is Suspension air key, and the hydroxyl of silanol easily forms firm chemical bond in conjunction with glass surface, therefore organosilan
Effect such as " double-sided adhesive " improves Water-based glass baking paint to glass attachment to reach firmly by resin together with glassy bond
The purpose of power, at the same keep water-based acrylic resin paint film property preferably, protect light, weatherability the advantages that.
(2) novel environment-friendly water-based glass baking varnish of the invention, it is aqueous poly- using water based acrylic resin as film-forming resin
Urethane resin is curing agent, so that the molecular tie of water based acrylic resin and waterborne polyurethane resin is at 3 D stereo net
Network structure, to improve coating paint film property.
(3) novel environment-friendly water-based glass baking varnish of the invention adds organosilan adhesion promoter, further increases water
Property glass baking varnish is to glass attachment power.The main component of glass is SiO2, and structure has longrange disorder, shortrange order, orientation
The features such as property is strong, therefore glass surface is very bright and clean, it is necessary to suitable adhesion promoter is introduced, coating can be enhanced in glass
The adhesive force on surface, but common adhesive promoter is easy to make paint film xanthochromia, and the present invention is with γ-(2,3 glycidoxy)
Propyl trimethoxy silicane is adhesion promoter, can make after the resistance to 55% alcohol solution dipping 172h of paint film still non yellowing, and attached
Put forth effort not decline.
(4) novel environment-friendly water-based glass baking varnish of the invention is added to wetting agent, can reduce surface tension, so as to
Phenomena such as effectivelying prevent paint film shrinkage cavity, pinprick, volcanic crater and indent generation.
