Problems solved by technology

However, there are some shortcomings in the traditional high-temperature adhesive resin used in high-temperature insulation materials: high-temperature adhesive resins mostly use epoxy, phenolic and other resins as the main body of the adhesive resin, supplemented by high-purity graphite powder or ceramic powder, etc. Heat-resistant fillers, and with the addition of these heat-resistant fillers, especially the increase in high thermal conductivity fillers, the density and thermal conductivity of the bonding layer will increase accordingly
In order to obtain the high structural strength of the bonding, the cohesive strength of the bonding resin layer and the compactness of the structure are deliberately pursued, which will eventually lead to an increase in the overall density of the insulation material, and the thermal conductivity of the material will also increase with the increase of the density, which is obvious. Not conducive to high temperature insulation behavior

Abstract

The invention specifically relates to a special bonding resin applied to lining stainless steel composite pipes, and preparation and application thereof, belonging to the technical field of high polymers. The bonding resin is prepared from the following raw materials by weight: 50-100 parts of polyethylene, 30-50 parts of ethyl acetoacetate, 10-30 parts of diethylene glycol ethyl ether acetate, 5-10 parts of a solid powdery filler and 1 to 5 parts of succinic anhydride. According to the invention, the special bonding resin is prepared on the basis of the characteristics that polyethylene is cheap, ethyl acetoacetate leaves few residues during high-temperature carbonization and diethylene glycol ethyl ether acetate has a great amount of residual carbon during high-temperature carbonization;and a large number of pores are left after carbonization of polyethylene, residual glassy carbon of ethyl acetoacetate and diethylene glycol ethyl ether acetate forms porous carbon in virtue of the pores, thereby forming a porous low-density carbon material layer with low thermal conductivity and the dual functions of heat preservation and bonding.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to a special adhesive resin for lining stainless steel composite pipes and its preparation and application. Background technique [0002] Bonding is a simple and easy way, and various countries in the world are competing to develop high-temperature bonding resins. However, there are some shortcomings in the traditional high-temperature adhesive resin used in high-temperature insulation materials: high-temperature adhesive resins mostly use epoxy, phenolic and other resins as the main body of the adhesive resin, supplemented by high-purity graphite powder or ceramic powder, etc. Heat-resistant fillers, and with the addition of these heat-resistant fillers, especially the increase in high thermal conductivity fillers, the density and thermal conductivity of the bonding layer will increase accordingly. This is especially prominent on the laminated carbon felt bonded...
