Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape production, in particular to a drying box for preparing a flame-retardant thermosetting adhesive tape for vehicles. Background Art

[0002] In terms of automotive interiors and electrical circuits, materials with flame retardant, high temperature resistance, insulation and other properties are required. As a new type of high-performance material, automotive flame retardant thermosetting tape can meet these requirements and has been widely used in the automotive industry. However, most of the automotive flame retardant thermosetting tapes on the market currently use traditional preparation methods, and their performance and quality are often affected by factors such as raw materials and processes. Therefore, it is of great practical significance and application value to study new preparation methods for automotive flame retardant thermosetting tapes and improve the performance and quality of products.

[0003] When it is necessary to produce this tape, it is necessary to first use a weighing device to accurately weigh the required flame retardant, adhesive, tackifier, polyethylene and other additives, put these raw materials into a stirrer, stir at a low speed until they are evenly mixed, and then put the mixed raw materials into a high-speed disperser or a planetary mixer, stir at a high speed, so that the flame retardant and other additives are evenly dispersed in the adhesive, and after high-speed stirring, pour the mixed rubber into the hopper of the coater, adjust the speed and pressure of the coater, so that the rubber is evenly coated on the substrate (such as polyester film or cloth base), and then put the coated substrate into a hot press or an oven for high-temperature and high-pressure curing to completely cure the adhesive and enhance the flame retardant performance, and finally use a winder to wind the produced tape onto the corresponding tape sleeve and package it. This tape and the production method used to produce this lower can be called a drying oven for preparing automotive flame-retardant thermosetting tape;

[0004] This automotive flame-retardant thermosetting tape has the problems of poor elasticity and complicated production process. The patent number CN117625079A, whose name is a composite tape for OLED screen protection and its preparation method, adds MDT silicone resin and graphene additives to the raw materials during the mixing process of the raw materials, thereby improving the elasticity of the finished tape itself.

[0005] However, this automotive flame-retardant thermosetting tape may be working in a high-temperature and high-risk environment for a long time, and its own flame retardancy and its viscosity are difficult to play a role in a high-temperature environment for a long time; therefore, it does not meet the existing needs.

The rotating mixing blades 226 can stir the viscous resin and the nano-adhesive substance to mix them. The mixed liquid will enter the inside of the strip grooves 206 through the thin metal tubes 223, and will be heated by the heating performance of the multifunctional coating and drying box 1 itself, so that it will be mixed with the rubber material 202 in the contact position therewith.
