Abstract
The invention relates to an acrylic acid-polyurethane resin A for a water dispersible paint and a preparation method thereof. The invention is characterized in that the acrylic acid-polyurethane resin A for the water dispersible paint mainly comprises methyl isobutyl ketone, acrylic acid, 2-hydroxyethyl methacrylate, n-butyl acrylate, 2-ethylhexyl acrylate, styrene, tert-butylperoxy-2-ethylhexoate, methyl isobutyl ketone and the like. The acrylic acid-polyurethane resin A for the water dispersible paint does not agglomerate or settle and has excellent storage stability; a film prepared from the paint has the characteristics of good appearance, strong adhesion, high glossiness, toughness, etc.
Description
Technical field
The present invention relates to a kind of water-dispersion coating with acrylic acid-polyurethane Resin A and preparation method thereof, belong to chemistry painting industry protection field.
Background technology
Bi-component acrylic-polyurethane water-based paint; Have good adhesive, snappiness and wear resistance; From external bi-component acrylic of the sixties-polyurethane water-based paint development rapidly, and the research of the bi-component acrylic-polyurethane water-based paint of China starts from the seventies, in recent years; The bi-component acrylic of China-polyurethane water-based paint development is very fast, but all has big gap with external than its output and performance.
At present; The coating that China is used for industries such as machinery, light industry, chemical industry, metallurgy adopts acrylic coating mostly; But sticking power, the snappiness of acrylic coating are relatively poor; And the polyurethane coating of China is a main flow with two-pack alcohol acid and polyurethane coating, has good sticking power and wear resistance, but its hardness, high thermal resistance are than acrylic coating difference.Through the two graft copolymerization or interpenetrating(polymer)networks modification; Can obtain the bi-component acrylic-polyurethane water-based paint of two kinds of resin advantages of honest and clean tool acrylic acid-polyurethane; Coating system with aliphatics polyisocyanates and Hydroxylated acrylic resin compatibility has abroad appearred; And technological comparative maturity, but China's report in this respect is less.In order to promote and improve China's bi-component acrylic-polyurethane water-based paint industrial expansion, utilization of the present invention contains poly-hydroxy vinyl resin and the reaction of HDI biuret polyisocyanate, prepares a kind of novel bi-component acrylic-polyurethane water-based paint resin; Bi-component acrylic-the polyurethane water-based paint of this resin preparation have do not condense, not sedimentation; Package stability is excellent, and the appearance of film of processing is fine, strong adhesion; Characteristics such as glossiness is high, and paint film is hard.
Summary of the invention
In order to solve the technical problem of above-mentioned existence; The objective of the invention is to provide a kind of water-dispersion coating with acrylic acid-polyurethane Resin A and preparation method thereof, it is characterized in that this water-dispersion coating with the acrylic acid-polyurethane Resin A mainly by: MIBK (1), vinylformic acid, methylacrylic acid 2-hydroxyl ethyl ester, n-butyl acrylate, ethyl acrylate, vinylbenzene, t-butyl peroxy-2-ethylhexyl (1), t-butyl peroxy-2-ethylhexyl (2) MIBK (2) etc. are formed.
Described a kind of water-dispersion coating is used the acrylic acid-polyurethane Resin A.By being: MIBK (1) 35～40 with weight part; Vinylformic acid 2.0～6.0; Methylacrylic acid 2-hydroxyl ethyl ester 10～15; N-butyl acrylate 15～22; Ethyl acrylate 10～15; Vinylbenzene 10～15; T-butyl peroxy-2-ethylhexyl (1) 1.0～3.0; T-butyl peroxy-2-ethylhexyl (1) 0.1～0.3; MIBK (2) 1.0～3.0 compositions such as grade.
