Abstract
The invention discloses a formula of a PU adhesive, comprising polyurethane, a curing agent and a diluent which are in a weight ratio of 1:(0.02-0.08):(2-5). A preparation method of the PU adhesive comprises the following steps: (1) adding polyurethane in any quantity by weight into a container, and then adding the diluent which is 2-5 times as heavy as the added polyurethane and stirring uniformly; and (2) adding the curing agent which is 2-8% time as heavy as polyurethane and finally stirring uniformly. According to the formula of the PU adhesive based on the scheme disclosed by the invention, the raw materials are easily available and the ratio of polyurethane to the curing agent to the diluent is reasonable. The preparation method of the PU adhesive based on the scheme disclosed by the invention has the advantages that the preparation is simple, the preparation speed is high and the requirement for mass production of protective films can be met.
Description
Technical field
The present invention relates to a kind of PU glue formula and preparation method thereof, particularly relate to PU glue formula used in a kind of protective membrane production process and preparation method thereof, belong to screen protection technical field of membrane.
Background technology
Protective membrane can be divided into protective film for digital product according to purposes, protection film for automobile, family expenses protective membrane, food fresh keeping protective membrane etc.Along with universal in China of the digital products such as mobile phone, the protective membrane one becoming screen protecting film is slowly referred to as.Simultaneously; along with continuous progress and the development of electronics technology; also getting more and more of the electronic product with screen that people have; make the demand of protective membrane also increasing; simultaneously; scientific and technological content with the electronic product of screen is also more and more higher, makes electronic product also more and more valuable, to protective membrane require also more and more higher.In protective membrane production process, need to use some colloids, as PU glue, PU glue and PU glue etc., according to the purposes of protective membrane, use different colloids.The usual more complicated of existing PU glue formula, and preparation method is loaded down with trivial details, cannot meet the Production requirement that protective membrane is a large amount of, and use the protective membrane that the PU glue of prior art is produced, the poor-performings such as venting quality, cannot meet the demand of existing high-tech electronic product.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose PU glue formula used in a kind of protective membrane production process and preparation method thereof.
Technical solution of the present invention is achieved in that a kind of PU glue formula, and it comprises urethane, solidifying agent and thinner; The weight ratio of described urethane, solidifying agent and thinner is 1:0.02 ~ 0.08:2 ~ 5.
Prepare a method for above-mentioned PU glue, comprise the following steps:
(1) in container, put into the urethane of any weight, then add the thinner of 2 ~ 5 times of weight polyurethane, stir;
(2) then add the solidifying agent of weight polyurethane 2 ~ 8% times, stir, complete preparation.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The PU glue formula of the present invention program, former material is simple and easy to get, and urethane, ratio between solidifying agent and thinner are reasonable.The preparation method of the PU glue of the present invention program, preparation is simple, and preparation speed is fast, can meet the Production requirement of a large amount of protective membrane.The present invention prepares the PU glue of gained, for the protection of in film, plays the cohesive action between materials at two layers, uses the protective membrane that this PU glue is produced, and the performances such as venting quality are all better, can meet the quality requirement of existing high-tech electronic product completely.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
1, PU glue is filled a prescription
Embodiment 1:
A PU glue formula, it comprises urethane, solidifying agent and thinner; The weight ratio of described urethane, solidifying agent and thinner is 1:0.02:2.
Embodiment 2:
A PU glue formula, it comprises urethane, solidifying agent and thinner; The weight ratio of described urethane, solidifying agent and thinner is 1:0.05:3.5.
Embodiment 3:
A PU glue formula, it comprises urethane, solidifying agent and thinner; The weight ratio of described urethane, solidifying agent and thinner is 1:0.08:5.
The PU glue formula of the present invention program, former material is simple and easy to get, and the ratio of urethane, solidifying agent and thinner is reasonable, can play the effect of each comfortable PU glue.
2, for the preparation method of PU glue
Embodiment 1:
(1) in container, put into the urethane of any weight, then add the thinner of 2 times of weight polyurethane, stir;
(2) then add the solidifying agent of weight polyurethane 2% times, stir, complete preparation.
Embodiment 2:
Prepare a method for above-mentioned PU glue, comprise the following steps:
(1) in container, put into the urethane of any weight, then add the thinner of 3.5 times of weight polyurethane, stir;
(2) then add the solidifying agent of weight polyurethane 5% times, stir, complete preparation.
Embodiment 3:
(1) in container, put into the urethane of any weight, then add the thinner of 5 times of weight polyurethane, stir;
(2) then add the solidifying agent of weight polyurethane 8% times, stir, complete preparation.
The preparation method of the PU glue of the present invention program, preparation is simple, and preparation speed is fast, can meet the Production requirement that protective membrane is a large amount of.
The present invention prepares the PU glue of gained, for the protection of in film, plays the cohesive action between materials at two layers, uses the protective membrane that this PU glue is produced, and the performances such as venting quality are all better, can meet the quality requirement of existing high-tech electronic product completely.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
