Description
Technical field
The present invention relates to polyurethane coating technical field, especially a kind of aqueous polyurethane environmental protection coating material.
Background technique
Coating, also known as film, paint film or coating, coating are a kind of organic chemical industry's macromolecular material again, and this material can
To be coated in body surface with different construction technologies, is formed and adhered to securely, with some strength, continuous solid film.It presses
Type of solvent divides, and coating generally comprises oil paint, water paint, powdery paints three classes.
Coating generally comprises four kinds of bases：It film forming matter (resin), pigment (including extender pigment), solvent and helps
Agent.Film forming matter is the main component of film, including grease, fats and oils processing product, cellulose derivative, natural resin and synthesis
Resin；It further include the volatile reactive diluent in part in film forming matter, reactive diluent is to be firmly attached to coating to be applied
The main matter that continuous film is formed on object, is the basis for constituting coating, decides the fundamental characteristics of coating.Auxiliary agent generally cannot
Film forming, but the process for forming film to base-material plays an important role with durability, such as defoaming agent, levelling agent, ground wetting
Agent etc..Pigment is divided into coloring pigment and two kinds of extender pigment, and common coloring pigment has titanium dioxide, chrome yellow etc., common constitution
Pigment has calcium carbonate, talcum powder etc..Solvent mainly makes filmogen disperse and form thick liquid, helps to construct and improve
Some performances of film；Wherein common solvent mainly includes water, hydrocarbon solvent, alcohols, ethers, ketone and Ester.It is existing
Coating of today is usually based on resin, and by adding corresponding auxiliary agent, selection adds or be not added pigment, filler as needed,
The thick liquid being formulated using organic solvent or water.And all contain Benzene and its compounds in organic solvent, and benzene compound
Strong carcinogen is determined as by the World Health Organization, when people absorbs the toluene of high concentration, dimethylbenzene in a short time, meeting
There is the symptom of nervous centralis anesthesia, less serious case will appear the symptoms such as dizzy, nauseous, uncomfortable in chest, out of strength, will appear when serious stupor,
Circulatory failure and it is dead.Benzene is to the irritating effect of skin, eyes and respiratory tract, and often in contact with benzene, skin can become because of degreasing
It is dry, furfur, or even will appear allergic eczema.Most of wall finiss currently on the market has been all made of aqueous latex paint, but
Woodcare paint for furniture is still largely using solvent borne paint, and furniture woodenware solvent paint can distribute toxic organic compound, human body sucking
There is biggish damage to the respiratory system of human body afterwards, epidermal tissue's degreasing can occur and damage skin after human body touch
Wound, therefore the invention proposes a kind of aqueous polyurethane environmental protection coating material, it can be used in the brushing of furniture woodenware.
