Abstract
The invention discloses a water-washable non-setting adhesive, which consists of transparent non-setting adhesive sheets which are prepared by chemical reaction of a component A and a component B in full contact, wherein the component A is isocyanate, the component B is polyol, and the weight part ratio of the component A to the component B is 100:(18-34). According to the method, the high adhesive strength toughness, washability and high chemical adhesive strength with a substrate of the polyisocyanates are uncomparable to non-setting adhesives available in the market, and thus, a new application is developed for polyurethane adhesives.
Description
Technical field
The present invention relates to the daily living article technical field, specifically, it is that a kind of non-setting adhesive of washing is pasted.
The invention still further relates to the preparation method that a kind of non-setting adhesive of washing is pasted.
Background technology
Pressure-sensitive adhesive is commonly called as again non-setting adhesive, is called for short pressure sensitive adhesive.The pressure sensitive adhesive of industrial use mainly contains four large classes: solvent pressure-sensitive adhesive, emulsion-type pressure-sensitive, thermotropic pressure sensitive glue and ray curing pressure sensitive adhesive.
Pressure sensitive adhesive can be divided into rubber-like pressure sensitive adhesive, polyacrylate(s) pressure sensitive adhesive by its polymkeric substance, the emulsion-type pressure-sensitives such as polyvingl ether resene, polyisobutene class, in China in occupation of the absolute predominance status, large characteristic, especially an acrylate emulsion that is China's pressure sensitive adhesive industry has special importance in China.
But existing non-setting adhesive is on the market pasted ubiquity and following defective: one, and can not be rough stickup; Two, must apply certain pressure during use, it just can stick on the smooth object; Three, there is no carrying capacity.
On the other hand, non-setting adhesive is pasted and to be generally paper products, not only Pasting object but also can be used as used for decorative paper.But, because its intensity is low, water resistant not, if do not do any processing, non-setting adhesive stickup meeting loses viscosity or damage because of immersion.
Along with the raising of the level of consumption, people are more and more higher to the requirement of non-setting adhesive Paste Product, and common non-setting adhesive is pasted the requirement that can not satisfy users.
Therefore, a kind of water resisting property of the demand of demanding urgently can arbitrarily be pasted not trace, and the non-setting adhesive with certain carrying capacity pastes to substitute common non-setting adhesive stickup.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the purpose of this invention is to provide a kind ofly wash, can repeat to paste repeatedly, viscosity and soft durometer is adjustable, adhesive material is diversified, multi-functional non-setting adhesive is pasted.
The preparation method that purpose of the present invention also provides a kind of above-mentioned non-setting adhesive to paste.
For achieving the above object, the technical solution adopted in the present invention is: a kind of non-setting adhesive of washing is pasted, and is comprised of the transparent non-setting adhesive film layers, and described transparent non-setting adhesive film layers is made by A, the rear generation of B two component components contact chemical reaction; Described A component is isocyanic ester, and described B component is polyvalent alcohol, and described A, B two composition weight proportionings are 100 parts, 18-34 part.
Preferably, described A component is one or more in polyisocyanates and modification body thereof, tolylene diisocyanate, methane diphenyl vulcabond, the poly methylene poly phenyl poly isocyanate.
Preferably, described B component is a kind of or its mixture in polyester polyol or the polyether glycol.
Preferably, the saturating lamellar spacing of described transparent non-setting adhesive glue is 0.05 0.15cm.
The preparation method of above-mentioned non-setting adhesive may further comprise the steps: relative air humidity less than 50% condition under, with 100 parts by weight ratio of A B two components, 18 34 parts of mixing and stirring keep the mixture temperature less than 25 ℃ in the whipping process;
Then mixture is placed under the vacuum condition of 10Pa to be evacuated to without bubble, the mixture after vacuumizing is coated on the base material, at temperature 25-80 ℃, time 30-300s, gel solidification forms.
The non-setting adhesive stickup performance index that the present invention makes are as follows:
1, the extensibility of transparent non-setting adhesive film layers is 200% 1000%;
2, the adhesive power of transparent non-setting adhesive film layers is 1.0 5.0N/cm2;
3, but to stick on the carrying capacity on the material be 1 150 N to transparent non-setting adhesive.
Compare with existing non-setting adhesive stickup, the present invention has the following advantages:
1, can wash after making dirty, washing still can repeat to paste repeatedly later.
2, Pasting is on multiple level and smooth or rough material surface, such as materials such as timber, glass, plastics, clothes.
3, its stickup degree and soft durometer can be adjusted, and have the good property sheared, snappiness.
4, easy to process, use flexibly functional diversities.
The present invention is mainly made by polyisocyanates and polyvalent alcohol, and contain in the polyisocyanates molecular chain isocyano-(NCO) and carbamate groups (NH-COO-), therefore the present invention shows activity and the polarity of height, itself and the base material that contains reactive hydrogen, such as foam, plastics, timber, leather, fabric, paper, the porous materials such as pottery, and metal, glass, rubber, the material of any surface finish such as plastics has good chemical adhesive power, and wherein do not contain the objectionable impuritiess such as phthalic ester plasticizer, belong to the environmental protection starting material, can be by extensive use in automobile, timber, shoe-pad, packing, building, printing ink, bookbinding, railway construction.The present invention is because its excellent adhesion properties, can play an increasingly important role at aspects such as bonding, the historical relic's protection of space flight equipment and reparation, defense industry, stationery, health cares.
The present invention take full advantage of viscosity that polyisocyanates shows excellently, snappiness, washing property and with the chemical adhesive of base material excellence, not only can remedy the market defective that existing non-setting adhesive is pasted, also open up new Application Areas for polyurethane adhesive simultaneously.
