Abstract

The invention discloses preparation methods of a high-temperature-resistant adhesive and a high-temperature-resistant aluminum tape. The preparation method of the high-temperature-resistant adhesive comprises the following steps: preparation of a raw adhesive: S1, the raw adhesive is prepared from 30-40 parts of 2-ethylhexyl acrylate, 12-20 parts of butyl acrylate, 3-6 parts of acrylic acid, 1-5 parts of hydroxyethyl acrylate and 45-55 parts of toluene; S2, various raw materials are accurately weighed and uniformly stirred at normal temperature in a reactor, the reactor is heated to 110-120 DEG C, polymerization reaction is conducted at toluene reflux temperature for 8-12 h, and the raw adhesive is prepared; preparation of the adhesive: S3, the adhesive is prepared from the following components: 50-65 parts of the original adhesive, 15-18 parts of rosin tackifying resin, 18-22 parts of toluene and 0.5-2 parts of a crosslinking agent; S4, various raw materials in S3 are accurately weighed and uniformly stirred at normal temperature in the reactor for 5-8 h, and the high-temperature resistant adhesive is prepared. The aluminum tape prepared from the high-temperature resistant adhesive has high tensile strength, is easy to operate, green and environmentally friendly, can be pasted on site easily, improves pasting efficiency, and is suitable for machine pasting.

Description

technical field [0001] The invention relates to the technical field of adhesive materials, in particular to a preparation method of a high-temperature-resistant adhesive and a high-temperature-resistant aluminum foil tape. Background technique [0002] The tape is mainly composed of a base material and a layer of adhesive coated on one or both surfaces of the base material. By forming a bond between the adhesive molecules on the base material and the surface molecules of the object, the tape adheres on the surface of the item. Divided by function, tapes can be divided into high temperature tapes, pressure sensitive tapes, insulating tapes, special tapes, die-cut tapes, etc. [0003] Aluminum foil tape is a kind of metal foil tape with good viscosity, strong adhesion and good anti-aging performance. It is widely used in the joint bonding of all aluminum foil composite materials, the sealing of the punctured part of the insulation nail and the repair of the damaged part. It i...
