Abstract
The invention relates to a preparation process of anti-cracking paint. The anti-cracking paint comprises the following substances in percent by weight: 40-50% of nitrocotton, 20-25% of modified rosin resin, 10-15% of 325 amino acid resin, 2-5% of an adhesion promoter, 5-10% of zeolite powder, 10-15% of triethyl citrate and 5-10% of pigment. Through addition of the triethyl citrate as an enhancer, the defect that nitrolacquer is easy to crack is overcome; the preparation process is simple and low in cost, and has a wide application range.
Description
Technical field
The present invention relates to a kind of method of modifying of paint, more particularly to a kind of crack resistence paint and preparation method thereof, belong to
Organic chemical industry field.
Background technology
The history of paint can be traced back to before more than 4000 years, at that time China working people just using vegetable oil (as tung oil,
Chinese catalpa oil) and natural raw lacquer covering with paint tool face, solid rear film of the formation with protectiveness.B.C. 1500, France and
In Hispanic cavern, paint has been used for painting and decorates.B.C. 1500, Egyptian was for example indigo with dyestuff and madder manufactures
Blue and red pigment, but this paint is still far from perfect.18th century, due to the exploitation to linseed oil and zinc oxide,
Develop paint industry rapidly.20th century, painting technology has significant development, occurs in that adhesion strength bigger, glossiness is higher, hinders
Combustion, the anticorrosive paint with the high shades of colour of heat endurance.With scientific technological advance, especially oil in recent decades
Work and the rapid development of organic synthesis industry, many new material of paints are come out one after another.
At present paint is existing thousand of various, and the past is to painting Classification And Nomenclature very disunity.Chemical industry department of China, to oil
Paint is divided into 18 big class by the classification of paint based on its main film forming substance.By position classification is painted, wall is broadly divided into
Paint, metallic paint, woodcare paint.Wall paint includes exterior wall paint, interior wall paint and top surface paint, mainly emulsion paint；Metallic paint is mainly enamel paint；
Woodcare paint mainly has nitrate paint, Polyester Paint etc..
Nitrate paint is woodenware and finishing paint relatively common at present, and main film forming matter is based on nitrocotton, to coordinate
The soft or hard resin such as alkyd resin, modified rosin resin, acrylic resin, amino resins is collectively constituted, and solvent mainly has esters, ketone
The cosolvents such as class, alcohol ethers equal solvent, alcohols, and the diluent such as benzene class.Nitrate paint be mainly used in woodenware and furniture application,
The aspects such as house decoration, coated metal, general cement application.Nitrate paint is dried rapidly, to the less demanding of painting environment, has
Preferably hardness and brightness, but it has the disadvantage that use time slightly length is easy for out cracking drawback.Triethyl citrate is used as excellent
Plasticizer, be widely used in painting modified dosage.Triethyl citrate is added, can be interacted with nitrocotton in nitrate paint,
Making the orientation of intrinsic dipole in paint increases and causes intermolecular dipole-dipole force to increase, and increases paint adhesion power, so that paint
It is not easy to crack.
