Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
The invention discloses a kind of protective membrane of adhesive face softness, its structure as shown in Figure 1, comprises protective membrane body 100 and is attached to the adhesive face 200 of protective membrane body surface.Adhesive face due to traditional protective membrane all adopts sizing agent to make, and its adhesive face structural instability, easily comes off, and can not fit by secondary, adhesive face pliability is little simultaneously, and easily produce bubble after fitting with screen, result of use is poor.The present invention is by improving the composition of adhesive face; adhesive face is made to form a kind of cancellated molecular structure; the stability of adopting this molecular structure is high; can well fit with protective membrane body; difficult drop-off; the present invention simultaneously utilizes 7650 type resins as adhesive face, and its flexibility is strong, has automatic vent effect.Below, by embodiment, the present invention will be described in detail.
Embodiment 1
Present embodiment discloses a kind of protective membrane of adhesive face softness, the component of its adhesive face by weight, comprising:
Solvent 550 parts;
Linking agent 21 parts;
11 parts, solidifying agent;
Resin 1000 parts;
In the present embodiment, solvent comprises the different solvent orange 2 A of boiling point and solvent B mixes, and solvent orange 2 A is solvent TOL; Solvent B is solvent MEK, and the blending ratio of solvent orange 2 A and solvent B is 10:1.In practical application, solvent B also can select solvent IPA, and when selecting solvent IPA, the blending ratio of solvent orange 2 A and solvent B is 10:1.The solvent that the present embodiment have employed two kinds of volatilization temperatures different mixes; the adhesive face liquid in the present embodiment is made to present a kind of stepped volatilization effect; volatilize compared to a kind of moment of solvent; the character of the adhesive face liquid of the present embodiment is more stable, is conducive to adhesive face and the stable laminating of protective membrane body.
In the present embodiment, resin adopts 7650 type resins, concrete, can adopt 7650 resins of Dow Corning Corporation.Resin in the present embodiment is a kind of molecular structure of chain, is glial state (state of matter between liquid and solid), has good continuity and flexibility, be extremely suitable as the composition of adhesive face.
In the present embodiment, linking agent comprises 7387 type linking agents and the two kinds of linking agent mixing of 9250 type linking agents, and its blending ratio is 4:3.Wherein 7387 type linking agents can adopt 7387 linking agents of Dow Corning Corporation, and 9250 type linking agents can adopt 9250 linking agents of Dow Corning Corporation.Concrete, after 7387 type linking agents and resin reaction, make that the molecular resin shape of chain-like structure is a kind of is similar to netted molecular structure; this cancellated stability of molecule is high, and associativity is strong, stable the fitting with protective membrane body of energy; even if repeatedly tear laminating, adhesive face also can not come off.Simultaneously at the contact surface of adhesive face with screen, adhesive face present a kind of softness, be with sticking character, what adhesive face can be stable fit with screen, and the adhesive face of softness has certain automatic ventilating function, laminating bubble-free generation afterwards.
In the present embodiment, 4000 solidifying agent of Dow Corning Corporation selected by solidifying agent.
In the present embodiment, the concrete steps of producing protective membrane are as follows:
A1: the 85%-90% getting the amount of 7650 type resins, 7387 type linking agents, 9250 type linking agents, solvent B and solvent orange 2 A, adds in agitation vat, stirs 35 minutes; Wherein solvent B selects solvent IPA or solvent MEK, and solvent orange 2 A selects solvent TOL; Produce a kind of cancellated molecular structure after 7650 type resins and the reaction of 7387 type linking agents, this cancellated stability of molecule is high, and associativity is strong, and stable the fitting with protective membrane body of energy, even if repeatedly tear laminating, adhesive face also can not come off.Simultaneously at the contact surface of adhesive face with screen, adhesive face present a kind of softness, be with sticking character, what adhesive face can be stable fit with screen, and the adhesive face of softness has certain automatic ventilating function, laminating bubble-free generation afterwards.
A2:; Solvent orange 2 A under remainder dilutes 4000 type solidifying agent, adds in agitation vat, stir 4000 type solidifying agent after dilution 15 minutes, obtained adhesive face liquid.
In practical application, protective membrane body is PET film, and in order to improve the baking and curing effect of adhesive face, what make that it can be stable fits with PET film, in the present embodiment, in step b, coating machine unreel speed control between 12-16M/min.
In step b in the present embodiment and c, adopt traditional protective membrane production technique, but must note regulating the speed unreeled with rolling, to reach best effect.
The adhesive face pliability that the present embodiment produces the protective membrane obtained is high, fits stable with PET film, though repeatedly protective membrane and screen are torn be separated after fit again, adhesive face also can not come off and remain on screen.Simultaneously at the contact surface of adhesive face with screen, adhesive face present a kind of softness, be with sticking character, what adhesive face can be stable fit with screen, and the adhesive face of softness has certain automatic ventilating function, laminating bubble-free generation afterwards.
In the present invention; the address of the raw material of above-mentioned production protective membrane is that these chemicals are in tradition address on the market; such as 7387 type linking agents (this address is the code name of product), are commonly considered as the linking agent of the same with 7387 linking agent character of Dow Corning Corporation (or very similar).Therefore; though the present invention adopts the tradition address of chemical agent; but not limiting can only be with this kind of chemical agent; the chemical agent identical or quite similar with this chemical agent character all falls within the scope of protection of the present invention; such as 7387 linking agents adopting Dow Corning Corporation disclosed in the embodiment of the present invention; but not only limit 7387 linking agents that can only adopt Dow Corning Corporation; any chemical agent identical with 7387 linking agent character of Dow Corning Corporation all can substitute 7387 linking agents of Dow Corning Corporation, does not enumerate at this.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
