Description
Technical field
The invention belongs to floor paint technical fields, and in particular to a kind of aqueous terrace topcoat paint and preparation method thereof.
Background technique
Floor paint (Floor paint) be it is a kind of can securely be covered on body surface, rise protection, decoration, mark and other
The chemical mixture coating of specific use is to be invented by Germany in 1934 earliest.Floor paint is mainly by oil plant, tree material, face
Material, solvent etc. are made, and are divided into decorative floor paint, heavy antisepsis floor paint, resistance to heavily loaded floor paint etc., by a variety of different materials through mixed
Many end production process such as conjunction, dissolution, dispersion are fabricated, and have the characteristics that beautiful, true, beautiful, wear-resisting, waterproof, anti-corrosion.
There are many dust proof workshop terraces in eighties of last century middle and later periods, America and Europe, such as epoxide terrace, abrasion-proof terrace etc., finally by
It is progressive enter every country, nowadays, in some factory floors, the application in laboratory, parking lot is more universal.Floor paint is developed to
The present, because it is with excellent physical mechanical property, electrical insulation capability, the performances such as excellent resistant to chemical etching, in each of national economy
A field is widely applied, and product is continuously increased, and quality is continuously improved, and new varieties continue to bring out.With economic height
Speed development, promotes floor coatings to enter prosperity and development period, while requirement of the people to floor coatings is also higher and higher.
Floor paint is classified according to material, mainly there is epoxide terrace paint and two kinds of polyurethane floor paint.Epoxide terrace has
Following advantages: waterproof, mould proof, impervious；Wear-resisting, can walk heavy vehicle；With preferable toughness, not delamination is hit, no
Cracking；Epoxide terrace is firmly bonded with base (concrete, ceramic tile, metal etc.), under the premise of construction quality guarantees, is not taken off
Layer, does not crack.The shortcomings that epoxide terrace is: adhesion strength is poor；High temperature resistance is poor；Weatherability is poor: epoxy resin
Terrace anti-uv-ray is poor, is unable to prolonged application in outdoor, otherwise can accelerated ageing, such as discoloration reduces intensity or even powder
