Abstract

A reimpression protective film contains a substrate layer, a reimpression coating, an organosilicon pressure-sensitive adhesive layer and matt release paper. The matt release paper is formed by successively stacking a first lamination layer, a release paper raw paper layer, a second lamination layer, a matt coating and a release agent coating. The lamination layers are respectively coated with a matt coating agent. The reimpression protective film is obtained by the following technology: 0.3-1 part of nano-SiO2 powder, 0.2-0.6 part of nano-Al2O3 powder and 0.3-1 part of a silane coupling agent are added into 8-10 parts of toluene and ultrasonic treatment is carried out to obtain a pre-dispersion liquid; 100 parts of vinyl siloxane and 0.3-1 part of hydrosiloxane are added into 120-150 parts of butanone and mechanical agitation is performed to obtain a polymer solution; the pre-dispersion liquid and the polymer solution are mixed, and mechanical agitation and ultrasonic agitation are successively carried out; and 0.2-0.5 part of platinum is added into the modulated polymer solution, and mechanical agitation and ultrasonic agitation are successively carried out. By the use of the reimpression protective film, the organosilicon rubber surface has a good haze effect, and the rubber surface achieves a low-reflectivity effect. In addition, surface roughness uniformity of the matt coating which contacts with the release agent coating is enhanced.

Description

New print diaphragm
Technical field
The present invention relates to a kind of diaphragm, particularly a kind of new print diaphragm.
Background technology
The products such as film face-plate is Mobile phone touch button such as, thin film switch are in carrying and use procedure, and its surface is easily subject to contact staining or polishing scratch scratches, and usually adopt diaphragm to cover its surface and make it from damage and pollute.Diaphragm is generally made up of substrate layer and the adhesive layer be coated on this substrate layer.When diaphragm is used for protecting various film face-plate such as Mobile phone touch button, during the products such as thin film switch surperficial, need printing word, pattern etc. on diaphragm, traditional diaphragm is general all not through wear-resisting new print process, is therefore difficult to carry out presswork on diaphragm; Secondly; when in new print diaphragm, release liners attaches with the pad pasting being coated with trowel adhesive; the mould release coating in release liners is easily caused to be taken away by the adhesive that adhesion is larger; thus form in the local surfaces of pad pasting the mould release coating area being difficult to clean out, destroy pure, the uniformity of pad pasting entirety.
Summary of the invention
The invention provides a kind of new print diaphragm, this new print diaphragm makes organic silica gel face mist degree effective, makes glue face reach low reflecting effect; And improve the cloudy surface Coating Surface Roughness uniformity with mould release coating layer touch, solve the leaching membrane layer of release liners and the technical problem of mould release coating binding force instability, be conducive to peeling off and avoiding residual pressure sensitive adhesive and mould release is residued on pressure-sensitive adhesive layer.
For achieving the above object, the technical solution used in the present invention is: a kind of new print diaphragm, comprise a substrate layer, this substrate layer applied atop one is for the new print coating of printing-ink, this substrate layer lower surface is bonded with a cloudy-surface release paper by silicone pressure sensitive glue-line and is connected, described cloudy-surface release paper is stacked gradually by the first leaching membrane layer, release liners original paper layer, the second leaching membrane layer, cloudy surface coating and mould release coating and forms, and described cloudy surface coating is 2.821um ~ 3.324um towards the surface roughness on the surface of described mould release coating; Described preparation technology forms primarily of the following step:
The first step: in the both side surface of release liners body paper, with film machine each film one deck leaching membrane layer, then cools;
Second step: apply the cloudy surface coating agent that a layer thickness is 0.2 ~ 2 micron on any leaching membrane layer, this cloudy surface coating agent obtains further by following technique:
Step 1. is by 0.3 ~ 1 part of Nano-meter SiO_2 2powder, 0.2 ~ 0.6 part of nanometer Al 2o 3powder and 0.3 ~ 1 part of silane coupler add in 8 ~ 10 parts of toluene and carry out ultrasonic wave process and obtain pre-dispersed liquid;
100 parts of vinylsiloxanes, 0.3 ~ 1 part of hydrogen-containing siloxane add in 120 ~ 150 parts of butanone by step 2. to carry out mechanical agitation and obtains polymer solution;
The mixing of the polymer solution of the pre-dispersed liquid of step 1, step 2 is also carried out mechanical agitation to step 3. successively and ultrasonic wave stirs, thus obtain the polymer solution after modulation;
The polymer solution of step 4. after described modulation adds 0.2 ~ 0.5 part of platinum and carries out mechanical agitation and the release solvent of the ultrasonic wave stirring described cloudy surface of acquisition successively;
3rd step: the cloudy surface coating agent of release liners is carried out polymerisation by baking and obtains cloudy surface coating;
4th step: apply one deck mould release coating on the surface of described cloudy surface coating.
The technical scheme improved further in technique scheme is as follows:
1. in such scheme, described Nano-meter SiO_2 2the diameter range of powder is 10 ~ 15nm, described nanometer Al 2o 3the diameter range of powder is 25 ~ 35nm.
2., in such scheme, the material of first, second leaching membrane layer described is PETG, polypropylene, polyethylene or polyvinyl chloride.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
