Description
Technical field
The invention belongs to paint fields, and in particular to a kind of aqueous peelable paint further relates to the preparation side of above-mentioned coating
Method.
Background technology
Stripable paint is commonly used in various metals, glass, plastics, ceramics, rubber and the smooth table of various high molecular materials
The temporary protection in face, it is easy to use.In the related material of aerospace, electrical instrumentation material, industrial precise materials and building fill
The industries such as exterior material, the equipment such as material, instrument and parts are easy to be wiped in transport, storage, processing and assembling process
Wound, abrasion, pollution, are also easy to receive the erosion of salt fog, moisture, acid rain, microorganism etc., to which chemical attack and electrochemistry occur
Corrosion, influences the exterior appearance of equipment, or even performance can be made to decline.In order to reduce these damages, extend the service life of equipment,
It needs effectively to seal protection up for safekeeping to equipment progress.For raw material and semi-finished product, it is also necessary to carry out subsequent processing or assembling etc.
Process, it is desirable that the cleaning of holding surface, therefore cannot be protected by modes such as rust prevention by applying liquid material paints, use peelable protective film
It is to solve the problems, such as most effective, most convenient the method.
Currently, in the product of Stripable paint, technically have the following problems：
1. solvent type Stripable paint discharges a large amount of VOC at the construction field (site), it is unfavorable for workers ' health, is unfavorable for environmental protection,
The policy that development environment-friendly type coating is widelyd popularize with country runs in the opposite direction.
2. existing aqueous Stripable paint in the market, for relative solvent type, want poor in the performances such as mechanical strength.
3. Stripable paint is directed to different base materials, adhesion performance is variant, can not accomplish adjustable.
Therefore, it is necessary to be improved for above-mentioned defect, a kind of better performances such as mechanical strength are designed, and for not
The same adjustable coating of base material.
Invention content
In order to solve the above technical problems, the present invention provides a kind of aqueous Stripable paint of high intensity, the coating
Tensile strength, elongation at break is all higher, and the adhesive force on various base materials is also preferable.
Idea of the invention is that：
The present invention has selected special modified resin, is ensureing that paint film cohesive force is sufficiently strong, can support its mechanical strength
On the basis of, the amount of accelerating agent and the selection of resin by the adjustment of formula, can be mainly removed, paint film can be adjusted and existed
Adhesive force on various base materials, to meet actual use demand.
Aqueous Stripable paint includes the component of following portions by weight：
Thickener is polyurethane association type auxiliary rheological agents.
Conven-tional adjuvants are one or more combinations in waterborne organic silicon antifoaming agent, amine neutralizer and substrate wetting agents.
Stripping accelerating agent is water paint film stripping agent.
The preparation method of above-mentioned aqueous Stripable paint, including following steps：
Each raw material is taken by parts by weight below：
By in above raw material input high-speed dispersion equipment, it is uniformly mixed with 800 revs/min of speed, obtains finished product.
The beneficial effects of the present invention are aqueous Stripable paint tensile strength provided by the present invention is high, extension at break
Rate is excellent, and peel strength is adjustable, environmentally protective.The design parameter detected is：8.08~11.05MPa of tensile strength, fracture are stretched
Long rate 400~800%, 5~10kN/m of peel strength.
Specific implementation mode
The present invention is further described with reference to specific embodiment, so that those skilled in the art knows more about
The present invention, but be not intended to limit the present invention.
Different base materials, surface topography and chemical group Chengdu are different, so same Stripable paint, in difference
Substrate surface application, adhesive force is different peel strength in other words.For example, glass surface has many hydroxyls, paint film to exist
When solidification, some functional groups in resin will be paint film with the hydroxyl reaction of glass surface, macro manifestations in glass table
The adhesive force in face is good, and paint stripping intensity is just high.To general paint film substrate surface adhesive force, usually with cross-hatching or
Person's hubbing characterizes.And for Stripable paint, generally characterized with peel strength.
