Description

Technical Field

[0001] The present application relates to the technical field of dust removal, and more specifically, to a dust-sticky paper, a preparation method and a dust-sticky roller. Background Art

[0002] There are stubborn garbage such as chewing gum, spider webs, hair, etc. on the floor and walls of the house, or in corners and under the bed that are difficult to clean. Conventional mops cannot completely clean them, and will leave water stains on the floor, making the room damp. Although the sweeping robots on the market can avoid this, they only suck up the dust on the floor. The cleaning efficiency of large-sized garbage and spider webs in hidden corners such as walls and bedsides is low or difficult to clean.

[0003] The sticky dust roller and the sticky hair roller are designed in the shape of a roller and are used with sticky dust paper. The sticky dust paper is provided with pre-cut lines and the edge of the roller has a peeling point for easy peeling. It is easy to use with the handle. It can not only remove dust well, but also avoid the shortcomings of traditional tools such as rags, washing water, brooms, etc., which are not convenient or comprehensive to clean. When using it, you only need to roll it on the surface of the object to be cleaned like painting a wall, and you can quickly remove various tiny particles, impurities, fibers, dust, hair, etc. The sticky dust paper is used in a circular manner during the production process to ensure the self-adhesion of the rubber wheel and greatly increase its service life.

[0004] Most of the adhesives for dust-proof and wool-proof papers are made by coating, and some are made by silicone. The coating method contains a lot of solvents, which seriously pollutes the environment; silicone can be reused, but the cost of silicone is high and the production process is complicated.

[0005] Regarding the existing dust-repellent paper and lint-repellent paper products, the inventor believes that they are less environmentally friendly and have higher production and use costs, and therefore still need to be improved and upgraded. Summary of the invention

[0006] In order to solve the above technical problems, the present application provides a sticky paper, a preparation method and a sticky roller. The preparation method of the sticky paper provided by the present application is simple, low in cost, does not contain organic solvents, and is more environmentally friendly. The sticky paper prepared by the present application is applied to a sticky roller, is easy to use, has high initial adhesion strength and is not easy to leave marks.

[0007] In the first aspect, the present application provides a dust-sticking paper, which adopts the following technical solution:

[0008] The adhesive layer comprises an adhesive layer and a substrate layer, wherein the adhesive layer is made of the following components in parts by weight: 8-12 parts of styrene-butadiene-styrene block copolymer, 2.5-4.5 parts of styrene-butadiene rubber, 15-20 parts of tackifying resin, 0.5-1 part of vinyl polysiloxane, 0.5-1 part of hydrogen-terminated dimethylsiloxane, 0.1-0.2 parts of antioxidant, 5-10 parts of filler oil, 1-3 parts of zinc oxide and 1-3 parts of white carbon black.

[0009] By adopting the above technical solution, the prepared dust sticky paper has high initial adhesion, and the adhesive layer has high peel strength, and it is not easy to leave marks when used. The present application adopts styrene-butadiene-styrene block copolymer and styrene-butadiene rubber as the base rubber of the adhesive layer, and the prepared dust sticky paper can effectively absorb various dirt; the present application adds a mixture of vinyl polysiloxane and hydrogen-terminated dimethylsiloxane to ensure that each component has good fluidity during the addition process, so that the rubber is not easy to agglomerate, so that the components can fully interact with each other to obtain a high-quality adhesive layer.

[0010] More preferably, the tackifying resin is one or more of hydrogenated rosin resin, terpene phenolic resin and coumarone-indene resin.

[0011] More preferably, the tackifying resin is a mixture of terpene phenolic resin and coumarone-indene resin in a weight ratio of 3:1.

[0012] By adopting the above technical solution, the addition of tackifying resin is mainly to impart and enhance the adhesiveness of rubber. According to the combination of the above resins in this application, the addition of the tackifying resin into the formula system can have good compatibility with the base rubber and resin, and impart higher peeling force and initial adhesion to the adhesive layer.

[0013] More preferably, the weight ratio of the vinyl polysiloxane to the hydrogen-terminated dimethylsiloxane is 1:1.

[0014] By adopting the above technical scheme, vinyl polysiloxane and hydrogen-terminated dimethylsiloxane can improve the low-temperature performance of the adhesive layer and the adhesion strength between the adhesive layer and the substrate. In addition, the addition of the mixture can also improve the viscosity of the adhesive layer, thereby effectively adsorbing various dirt. This may be because the mixture can prevent rubber and resin from agglomerating during processing, thereby improving the processing fluidity of each component and improving the product performance of the dust-sticking paper.

[0015] More preferably, the antioxidant is antioxidant 1010 or antioxidant 4020.

[0016] By adopting the above technical solution, the addition of the antioxidant can ensure that the components of the adhesive layer will not decompose or change color during the mixing and use process.

[0017] More preferably, the filler oil is one or more of cycloparaffin oil, alkane oil and paraffin oil.

[0018] By adopting the above technical solution, the addition of filler oil can improve the flowability and processability of rubber.

[0019] More preferably, the substrate is selected from the group consisting of film, fabric, non-woven fabric, and paper.

[0020] Preferably, the film may be polyethylene, vinyl chloride, polypropylene, polytetrafluoroethylene, etc.; the fabric may be cotton, viscose, PET, etc.; the paper may be masking paper.

[0021] More preferably, the silica is precipitated silica treated with hexamethyldisilazane.

[0022] By adopting the above technical solution, since the surface of white carbon black contains active hydroxyl groups, it is difficult to disperse in the system because it is easy to form hydrogen bonds between molecules. Adding white carbon black to the formula after surface treatment can effectively improve the peel strength and adhesion of the adhesive layer.

[0023] In a second aspect, the present application provides a method for preparing dust-sticky paper, using the following technical solution:

[0024] The method specifically comprises the following steps: melting styrene-butadiene-styrene block copolymer and styrene-butadiene rubber, then adding tackifying resin, vinyl polysiloxane, hydrogen-terminated dimethylsiloxane, antioxidant, filler oil, zinc oxide and white carbon black, stirring and mixing to obtain the product.

[0025] The method for preparing dust-sticking paper provided in the present application has simple steps, high processing efficiency, and is suitable for large-scale production.

[0026] In a third aspect, the present application provides a dust-sticking roller, which adopts the following technical solution:

[0027] A dust-sticking roller comprises a roller body and the above-mentioned dust-sticking paper, wherein the dust-sticking paper is attached to the curved surface of the roller body.

[0028] The sticky roller prepared by the present application is easy to use and has a wide range of applications. It is suitable for corners of the home that are difficult to clean and is also suitable for dust-free workshops. The sticky roller has high initial adhesion and leaves no marks when used.

[0029] In summary, this application has the following beneficial effects:

[0030] (1) The preparation method of the sticky paper provided by the present application is simple, low-cost, and does not contain organic solvents, which is more environmentally friendly. The sticky paper prepared by the present application is applied to the sticky roller, is easy to use, has high initial adhesion strength, and is not easy to leave marks;

[0031] (2) The tackifying resin used in the present application is a mixture of terpene phenolic resin and coumarone-indene resin, which can greatly improve the initial adhesion strength of the dust-proof paper and the peel strength of the adhesive layer;

[0032] (3) By adding vinyl polysiloxane and hydrogen-terminated dimethylsiloxane, the present application can improve the low-temperature performance of the adhesive layer and the adhesion strength between the adhesive layer and the substrate, and can further improve the adhesion of the adhesive layer, thereby effectively absorbing various dirt.

[0060] Application Examples

[0061] A dust removal roller is composed of a paper roller body and the dust sticking paper prepared in Examples 1-8, and the dust sticking paper is coated on the surface of the roller. It can be used in households, corners that are difficult to clean, clothing surfaces, and dust-free workshops, etc. When used, dirt can be removed by directly pulling the roller.

[0062] Performance testing

[0063] The sticky papers prepared in Examples 1-8 and Comparative Examples 1-4 were respectively tested for initial tackiness using the rolling ball method (32# ball) according to GB / T4852-2002; the 180° peel strength of the sticky papers was tested according to GB / T2792-2014; and the stickiness of the sticky papers was tested according to GB / T4851-2014. The test results are shown in Table 1.

[0064]

[0065] It can be seen from the test results of Examples 1-8 that the dust-sticking paper prepared in the present application has high initial tack, sustained tack and peel strength.

[0066] By comparing the test results of Example 1 and Examples 4-6, it can be seen that the composition of the tackifying resin can significantly affect the initial tack and peel strength of the sticky paper. This is because the mixture of terpene phenolic resin and coumarone-indene resin, in addition to being able to increase the viscosity of rubber, itself has good compatibility with rubber.

[0067] Comparing the test results of Example 1, Examples 7-8, and Comparative Examples 1-4, it can be seen that the addition of vinyl polysiloxane and hydrogen-terminated dimethyl siloxane can significantly improve the adhesion strength between the adhesive layer and the substrate, and greatly improve the adhesiveness of the dust-sticking paper, especially when vinyl polysiloxane and hydrogen-terminated dimethyl siloxane are mixed at a weight ratio of 1:1, the product performance is the best. Analysis of the reason may be that the mixture can effectively prevent the agglomeration phenomenon between rubber and resin during processing, thereby improving the processing fluidity of each component and giving full play to the performance of each component.

[0068] The above is only the preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under the concept of the present application belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
