Problems solved by technology

At present, there are few varieties of flame-retardant organic adhesives in China, and there is a big gap in application compared with foreign countries. Most of the flame-retardant products in the existing adhesive tapes are halogen flame-retardant, and the by-products pollute the environment and have low safety.

preparation example Construction

[0038] The preparation method of the above-mentioned organosilicon flame-retardant pressure-sensitive adhesive tape includes,

[0039] Step (1) taking a piece of release paper, pre-coating the adhesive on the release paper to obtain the first release paper with the adhesive;

[0040] Step (2) Dry the first release paper with adhesive through an electric blast drying oven set at 120°C for 10 minutes, take it out and cool it to room temperature;

[0041] Step (3) transferring the cooled first release paper to one side of the substrate layer, and peeling off the release paper simultaneously;

[0042] Step (4) Take another piece of release paper, repeat step (1) and step (2) to obtain the second release paper with adhesive, and then paste the pre-coated on the second release paper on the The other side of the substrate layer is rolled together with the release paper to obtain a silicone flame-retardant pressure-sensitive adhesive tape.

Embodiment 1

Abstract

The invention discloses an organic silicon flame-retardant pressure-sensitive adhesive tape. The organic silicon flame-retardant pressure-sensitive adhesive tape comprises a substrate layer, an adhesive agent layer and a release layer, wherein the substrate is a flame-retardant cotton paper layer; flame-retardant filler is filled with the inner part of the flame-retardant cotton paper layer; the flame-retardant filler is prepared from the following components in parts by weight: 30 parts to 50 parts of modified plant fibers, 8 parts to 10 parts of asbestos powder, 6 parts to 8 parts of flame-retardant fibers, 3 parts to 5 parts of nano-aluminum hydroxide, and 10 parts to 20 parts of vegetable glue. The invention also provides a preparation method of the organic silicon flame-retardant pressure-sensitive adhesive tape. The adhesive tape disclosed by the invention has high tensile strength, high softness performance, high viscosity and high stability while the adhesive tape has high flame retardance property; and compared with conventional halogen, the organic silicon flame-retardant pressure-sensitive adhesive tape is relatively high in flame retardance and is more environmentally friendly.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a silicone flame-retardant pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] With the rapid development of the industry, the existing adhesive tapes on the market meet some of people's needs to a certain extent, and are used more and more in electronic component systems in the fields of automobiles, household appliances, toy accessories, communications, aviation, and aerospace. Environmentally friendly tapes, especially in the aviation and aerospace fields, have higher requirements for tapes and require flame retardant requirements. The so-called flame retardant is non-combustible in case of fire and self-extinguishing when away from fire. The purpose can be achieved by adding appropriate flame retardants. At present, there are few varieties of flame-retardant organic adhesives in China, and there is a big gap in application compared with foreign...
