Abstract

The utility model provides crepe paper and a high-extension masking tape product. At least 80 crepes are arranged on each 10cm of the crepe paper, and the high-extension masking tape product comprises a substrate and crepe paper adhesives, wherein the substrate is made of the crepe paper, and the crepe paper adhesives are coated on at least one side of the substrate. As the substrate is made of the high crepe paper with at least 80 crepes, the masking tape product has 25%-100% stretch rate, and still has high adhesiveness while having the high stretch rate.

Description

U.S. line paper and the high masking tape goods that extend

Technical field

The utility model relates to a kind of U.S. line paper and the high masking tape goods that extend, relate in particular to use high-elongation that U.S. line paper makes and under high extension state, still have very strongly adherent high masking tape goods that extend.

Background technology

Masking tape is that a kind of high-tech is decorated, spraying paper using (because of its special purposes performance, being called again ribbon paper), and it is widely used in the spraying of spraying paint of interior decoration, household electrical appliance and high-grade limousine.Masking tape is take U.S. line paper and adhesive as main raw material, and adhesive coating on the one side of U.S. line paper applies adhesive (claiming again mould release) and the Wound adhesive tape made on the another side.Its minute, the chromatic effect boundary was clear, bright and clear, had again the camber line art effect concurrently, give decorate, the spraying industry brought once new technological revolution, the life that the sector is shone make new advances.

The general composition that is used at present the adhesive of making masking tape is: standard rubbers, butadiene-styrene rubber, SIS rubber etc. add some corresponding additives again.Existing produced masking tape can be used for irregular surface, curved surface bent angle, smooth surface or rough surface, after stretching by a small margin, still has very strong viscosity, but after stretch range increases viscosity aobvious inadequate by force, and can't cover for sharp edge, fit and will produce cull after 3 days.Existing masking tape does not have water proofing property in addition, can not be used for above the water paint.

For defects, be badly in need of providing a kind of brand-new height to extend the masking tape goods and solve the deficiencies in the prior art.

The utility model content

The application's technical problem to be solved provides has U.S. line paper and the masking tape goods that improve tensile property.

In order to address the above problem, the application discloses a kind of U.S. line paper, and the wrinkle number of the every 10cm of described U.S. line paper is not less than 80.

The application discloses a kind of high extension masking tape goods, described high extend the masking tape goods comprise the substrate of making of aforementioned U.S. line paper and coat at least one side of substrate U.S. line paper adhesive.

As further improvement of the utility model, the described high masking tape goods that extend comprise the U.S. line paper adhesive of coating substrate one side and the mould release of coating the substrate opposite side.

As further improvement of the utility model, described high extensibility of extending the masking tape goods is not less than 25%.

As further improvement of the utility model, when the every 10cm wrinkle of described U.S. line paper number was not less than 190, the described high percentage elongation that extends the masking tape goods was 25% ~ 100%.

As further improvement of the utility model, when described high extension masking tape goods extensibility reached maximum, its peeling force was for being not less than 0.52kg/25mm.

The utility model compared with prior art has following beneficial effect:

The U.S. line paper that the utility model provides and the high masking tape goods that extend are by adopting the U.S. line paper of high wrinkle (the wrinkle number is not less than 80) as substrate, thereby so that masking tape has 25% ~ 100% extensibility, and in the situation that high extensibility still has very strong viscosity.

Description of drawings

Fig. 1 is the high schematic diagram that extends masking tape of the utility model.

The specific embodiment

For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.

With reference to Fig. 1, present embodiment provides a kind of U.S. line paper and the high masking tape goods that extend, and the described high masking tape goods that extend comprise substrate 1, the U.S. line paper adhesive 2 of coating substrate 1 one sides and the mould release 3 of coating substrate 1 opposite side that U.S. line paper is done.

The wrinkle number of the every 10cm of described U.S. line paper is not less than 80.Described high extensibility of extending the masking tape goods is not less than 25%.When the number of the every 10cm of U.S. line paper was not less than 190, described high percentage elongation scope of extending the masking tape goods was 25% ~ 100%.When described high extension masking tape goods reached the maximum tension rate, its peeling force was not less than 0.52kg/25mm.

Used U.S. line paper adhesive belongs to the natural rubber type in the utility model, and each compositions in weight percentage is:

Rubber: 40-50%; Resin: 45-55%; Age resistor: 1-5%; Other composition: 1-5%.Wherein rubber comprises one or several in standard rubbers, butadiene-styrene rubber and the SIS rubber, described resin is viscosity resin once, age resistor comprises one or several in antioxidant A amine, the age resistor B dibutylamino zinc formate, and other compositions comprise zinc resinate promoter.Described once viscosity resin comprises one or several in terpene resin, C5 Petropols, C5/C9 Petropols, the ester gum.

The below provides some concrete experimental datas better to confirm technique effect of the present utility model.

Experiment form one:

Experiment form two:

Experiment form three

Experiment form four:

In the above-mentioned experiment form, it is big or small that experiment form one has been listed percentage elongation scope and the peeling force under maximum percentage elongation of the masking tape that the U.S. line paper U.S. line paper adhesive different with each weight percentages of components of different wrinkle numbers make.The percentage elongation scope of the masking tape that the U.S. line paper adhesive different with each weight percentages of components made when experiment form two to four had been listed respectively the every 10cm wrinkle of U.S. line paper number and is 80,135 and 200 and the size of the peeling force under maximum percentage elongation.

Be not difficult to find out from above-mentioned experiment form, when the every 10cm of U.S. line paper curl number reached 190, percentage elongation can reach 100%, and the peeling force under maximum percentage elongation is not less than 0.52kg/25mm; And when U.S. line paper curl number was not less than 80/10cm, percentage elongation was not less than 25%, and peeling force also is not less than 0.52kg/25mm simultaneously.

The U.S. line paper adhesive that the height extension masking tape goods that the utility model provides adopt in process of production is environment friendly and pollution-free.In use possess the function of water spray polishing, have water-proof function; The paper extensibility gets a promotion, and in the situation that high extensibility still has very strong viscosity; Possess in addition 80 ℃ of baking vanish functions under the temperature, use not cull in 7 days simultaneously; Can fit and cover narrower bent angle, sharp edges and irregular surface; Compatible various paint; And the utility model employing is made into brown, can act on brown any surperficial color separation in addition.

Although be the example purpose, preferred embodiment of the present utility model is disclosed, but those of ordinary skill in the art will recognize, in the situation that do not break away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
