Problems solved by technology

[0002] At present, there are two types of wet kraft paper tapes available in the market, with or without ribs. The ribs are only made of a simple quadrilateral glass fiber mesh structure technology, which has extremely poor stability and cannot increase the tensile strength of the tape; A single glass fiber quadrangular gauze is mechanically drawn, and there are usually broken yarns and yarn leaks, which seriously affect the strength of the tape; During the production and compounding process, the equipment is in a heating state, and when processing glass fiber yarn, it needs to be shut down. At this time, there is a problem of premature drying of the compounding adhesive, resulting in weak compounding of the top paper and bottom paper, and easy delamination

preparation example Construction

[0027] A preparation method of wet water kraft paper tape with ribs, which includes: respectively pulling kraft base paper, glass fiber yarn, and coated kraft paper coated with biodegradable materials into a composite device, and the composite device heats the coated kraft paper, and the biodegradable material Melting and compounding kraft base paper, glass fiber yarn and coated kraft paper to form sequentially connected face paper, reinforcement layer and bottom paper, and then coating wet water glue on the non-coated surface of the bottom paper to form a glue layer; Film kraft paper accounts for 40%-50% of the weight of the reinforced wet kraft paper tape, kraft base paper accounts for 24%-30% of the weight of the reinforced wet kraft paper tape, and glass fiber yarn accounts for 24%-30% of the weight of the reinforced wet kraft paper tape. The percentage is 5%-10% and the mass percentage of the wet water glue accounted for the wet water kraft paper tape with the ribs is 21%-...

Embodiment 1

[0033] see figure 1 and figure 2 , this embodiment provides a wet water kraft paper adhesive tape 100 with reinforcement and a preparation method thereof.

[0034] The structure of this rib wet water kraft paper adhesive tape 100 is as follows: it comprises base paper 101, face paper 102, reinforcing layer 103 and adhesive layer 104, and base paper 101 comprises coating surface 101a and non-coating surface 101b, and reinforcing layer 103 is arranged on Between the coated surface 101a and the facial paper 102, the adhesive layer 104 is connected to the non-coated surface 101b, and the reinforcement layer 103 includes a first reinforcement layer 103a and a second reinforcement layer 103b that are overlapped, and the first reinforcement layer 103a is a quadrilateral mesh Yarn, the second reinforcement layer 103b is radially laid on the surface of the first reinforcement layer 103a.

[0035]The preparation method of the ribbed wet water kraft paper tape 100 comprises: passing t...

Embodiment 2-5

[0039] Examples 2-5 provide a rib-entrained wet water kraft paper tape and a preparation method thereof. The structure and preparation method of the rib-enclosed wet water kraft paper tape are the same as those in the examples, the difference being that the ratio of raw materials and parameters are different.

Abstract

The invention provides a yarn-added water-wettable kraft paper gummed tape and a preparation method thereof and relates to the field of gumming substrates of gummed tapes. The yarn-added water-wettable kraft paper gummed tape comprises body paper, surface paper, a reinforced layer and a gum layer, wherein the body paper comprises a laminated surface and a non-laminated surface; the reinforced layer is arranged between the laminated surface and the surface paper; the gum layer is connected to the non-laminated surface. The yarn-added water-wettable kraft paper gummed tape is prepared from the following raw materials in percent by weight: 40%-50% of laminated kraft paper made into the body paper, 24%-30% of kraft base paper made into the surface paper, 5%-10% of glass fiber yarn made into the reinforced layer and 21%-25% of wet gum made into the gum layer; the laminated kraft paper is prepared by laminating a biodegradable material on the kraft paper. The yarn-added water-wettable kraftpaper gummed tape provided by the invention has the advantages that the laminating kraft paper is utilized for connecting the reinforced layer and the surface paper, so that the connecting effect is excellent, the toughness and the tensile strength are good, the benefit for degradation is achieved and the environment-friendly effect is better. The preparation method is simple, and the prepared yarn-added water-wettable kraft paper gummed tape is stable in structure, difficult in deformation and excellent in tensile strength.

Description

technical field [0001] The invention relates to the field of adhesive tapes for bonding base materials, in particular to a wet water kraft paper tape with ribs and a preparation method thereof. Background technique [0002] At present, there are two types of wet kraft paper tapes available in the market, with or without ribs. The ribs are only made of a simple quadrilateral glass fiber mesh structure technology, which has extremely poor stability and cannot increase the tensile strength of the tape; A single glass fiber quadrangular gauze is mechanically drawn, and there are usually broken yarns and yarn leaks, which seriously affect the strength of the tape; During the production and compounding process, the equipment is in a heating state, and when processing glass fiber yarn, it needs to be shut down. At this time, the compounding adhesive has the problem of drying in advance, resulting in weak compounding of the top paper and bottom paper, and easy delamination. Conten...
