Abstract
The invention discloses a kind of elastic polyurethane crackle coating, host includes the component of following parts by weight: elastic resin 20 50 parts；Drier 0 0.5 parts；Levelling agent 0 0.5 parts；Defoamer 0 0.5 parts；Host solvent 20 50 parts；10 15 parts of mute powder；Thixotropic agent 5 15 parts.The elastic polyurethane crackle coating of the present invention, having splendid elastic performance, the adjuvant system of appropriate mix, joins firming agent by a certain percentage and diluent is sprayed on polyurethane primer, there is fabulous elastic handfeel and excellent crackle aesthetic feeling, and hardness is high, adhesive force is good.Because the elastic polyurethane crackle coating of the present invention has fabulous hot strength, (spray the thickest by controlling coating thickness, crackle is the least, otherwise the thickest) and (degree of cross linking is the highest with the degree of cross linking of firming agent, crackle is the biggest, otherwise the least) various different crack effect can be formed, meet client's requirement to various different crack effect.
Description
Technical field
The present invention relates to a kind of polyurethane coating, particularly to a kind of polyurethane coating used on woodenware.
Background technology
Crackle coating on woodenware is by nitrocotton, pigment, extender pigment, organic solvent now, and adjuvant etc. grinds
The nitro crack coating of the formed shades of colour of mill modulation.Nitro paint belongs to volatility self-drying paint, need not add solidification
Agent, rate of drying is fast, and therefore nitro crack coating must in one or more layers nitro paint surface ability of same characteristic completely
Merge and represent crackle characteristic.Owing to nitro crack coating mealiness content is high, the volatility of solvent is big, thus its contractility
Greatly, pliability is little, and after spraying, internal stress produces higher tear-strength, forms crack pattern good, uniform, strengthens coating
Surface attractive in appearance, improves dicoration.But nitro paint also has some shortcomings clearly, such as: hardness xanthochromia inadequate, easy, attached
Put forth effort the most poor.
The shortcoming that polyurethane coating then eliminates nitro paint at a lot of aspects: there is higher hardness, the most resistance to
Huang and the attachment fabulous to ground.But existing polyurethane coating cannot realize the dicoration of crackle.
Summary of the invention
It is an object of the invention to overcome the above-mentioned deficiency of prior art, it is provided that a kind of hardness is high, yellowing resistance is good, adhesive force
Get well and possess the elastic polyurethane crackle coating of elastic handfeel.
The technical solution used in the present invention is:
A kind of elastic polyurethane crackle coating, it is characterised in that host includes the component of following parts by weight:
Elastic resin 20-50 part；
Drier 0-0.5 part；
Levelling agent 0-0.5 part；
Defoamer 0-0.5 part；
Host solvent 20-50 part；
Mute powder 10-15 part；
Thixotropic agent 5-15 part.
When the elastic polyurethane crackle coating of the present invention uses as white coating, host also includes following parts by weight
Component:
Titanium dioxide 20-30 part；
Divided titanium dioxide powder 0.5-1.5 part.
When the elastic polyurethane crackle coating of the present invention uses as blacking, host also includes following parts by weight
Component:

Described black slurry includes the component of following parts by weight:
Elastic resin 35-45 part；
White carbon black 5-15 part；
Carbon black disperser 4-6 part；
Black slurry solvent 40-50 part.
The firming agent of the elastic polyurethane crackle coating of the present invention includes the component of following parts by weight:
Aliphatic polymeric isocyanate 15-25 part；
Poly-isocyanurate 30-40 part；
Firming agent solvent 40-50 part.
Described host solvent is formed by butanone and ethyl acetate mix and match.
Described elastic resin selects acrylic acid modified middle long oil alkyd.
Aerosil selected by described thixotropic agent.
Described mute powder selects the mute powder of oiliness.
Described levelling agent selects oiliness silicone levelling agent.
Described defoamer is oiliness broken bubble polysiloxane defoaming agent.
Compared with prior art, the present invention achieves following superior technology effect: the elastic polyurethane crackle of the present invention
Coating, has splendid elastic performance, the adjuvant system of appropriate mix, joins firming agent by a certain percentage and diluent is sprayed at poly-
On urethane priming paint, there is fabulous elastic handfeel and excellent crackle aesthetic feeling, and hardness is high, adhesive force is good.Because of gathering of the present invention
Urethane elasticity crackle coating has fabulous hot strength, and by controlling coating thickness, (spraying the thickest, crackle is the least, otherwise gets over
Slightly) and with the degree of cross linking of firming agent (degree of cross linking is the highest, and crackle is the biggest, otherwise the least) various different crackle effect can be formed
Really, client's requirement to various different crack effect is met.
