Abstract

The invention relates to a method for preparing a coating transfer membrane. The method comprises the following steps: preparing a release layer; preparing a coating layer; preparing an adhesive layer; and sequentially coating the layers to a nonpolar resin substrate. The coating transfer membrane prepared through the method disclosed by the invention is convenient to use. According to the method, because coating is firstly coated to a nonpolar resin material, the coating can be fast transferred to a wall by utilizing the difficultly adhesive property of the nonpolar resin material; the problem of difficult cleaning of the wall can be effectively solved, so that the wall is fast restored into an original state; and the tint of a wall surface can be increased by increasing a decorative coating on the membrane.

Description

A kind of preparation method of coating transfer film

Technical field

The present invention relates to a kind of preparation method of film, relate in particular to a kind of preparation method of coating transfer film.

Background technology

Traditional coating has certain work-ing life, the overlong time variable color of can turning to be yellow, and most of coating scrape resistant not on the market at present, and also spot-resistant not, once have paint, ink etc. to adhere on wall, is just difficult to cleaning.

Summary of the invention

The present invention, for solving the problems of the technologies described above, provides a kind of preparation method of coating transfer film, can be succinctly, fast by pigment transfer to wall, removed the worry of cleaning wall from.

The present invention is that the technical scheme that technical solution problem adopts is:

A preparation method for coating transfer film, comprises the following steps:

(1) preparation of release layer

Pigment is progressively added to the water, under the condition that then low whipping speed is 1000-1500RPM/min, is stirred to pigment and disperses completely; ACRYLIC EMULSION is progressively mixed under the condition of 300-500RPM/min by formula order, under the condition of 1000-1500RPM/min, stir after emulsion mixes completely, with 400 order screen cloths, filter, standing standby after complete froth breaking;

Wherein said pigment is one or more in ultramarine, phthalocyanine blue, chrome yellow and chrome red; The weight ratio of wherein said pigment and ACRYLIC EMULSION is 1:1-1:5;

(2) preparation of dope layer

Polyvinyl alcohol is added to water and insert in reactor, under 50-100RPM/min condition, be heated to 95 ℃ of left and right, standby after polyvinyl alcohol dissolves completely; To after opalizer and weighting agent dissolving, add reactor dispersed with stirring; By adding reactor to stir after surfactant dissolves, treat that it dissolves completely, after solution mixes completely, with 300 order screen cloths, filter twice, standing standby after the complete froth breaking of solution;

(3) preparation of bonding coat

Polyvinyl alcohol is added to water and is placed in reactor, under 50-100RPM/min condition, be heated to 95 ℃ of left and right, to be bonded dose dissolve completely or gelatinization after standby; Add organic silicon surfactant, after solution mixes completely, with 300 order screen cloths, filter one time, standing standby after complete froth breaking; Wherein the weight ratio of organic silicon surfactant and polyvinyl alcohol is 1/100-10/100;

Releasing layer coating is applied on the non-polar resin base material that 0.05-0.2mm is thick, dries; Recycling coating machine is applied to dope layer on described base material, and coating thickness reaches 98% above shading rate with paint film and is as the criterion, and according to the difference of coating method, can be coated with multipass; After drying completely, bonding coat coating is coated to dope layer.

Preferably, after applying release layer, apply dope layer before, can on the base material that applies release layer, increase other decorative coveringns.

Preferably, the method that increases other decorative coveringns can be coating pigment and/or printing.

Coating transfer film of the present invention is easy to use, because first coating be coated on non-polar resin material, utilizes the difficult bond performance of non-polar material, can be fast by pigment transfer to wall.The difficulty that can effectively solve wall is cleaned problem, makes the fast quick-recovery virgin state of wall, meanwhile, by increase decorative coveringn on film, also can increase metope tone.
