Problems solved by technology

[0004] However, since the above-mentioned aromatic amine-based epoxy resin adhesive requires high temperature for curing, the resin cylinder will be distorted due to excessive expansion when it is hardened, causing the roller to be cut and damaged during operation.
Plus, due to its high viscosity, it is difficult to inject it into gaps of several millimeters at low temperatures

manufacture example 1

[0091] In a 2L glass container, put 80 parts of Ebicot epoxy resin 828 (manufactured by Yukaxiu Luo Yubao Kexi (シュルユポキシ) company; bisphenol A type epoxy resin, 20 parts of GOT (Nippon Kayaku Co., Ltd.; glycidyl-O-toluidine), when stirred at 80°C for 30 minutes, a light yellow transparent liquid with a viscosity of 3000mPa.s (25°C) was obtained. This was used as the main ingredient (1).

manufacture example 2

[0093] Except that 80 parts of Epicott epoxy resin 828, 10 parts of GOT, and 10 parts of GAN (manufactured by Nippon Kayaku Co., Ltd.; N, N-diglycidylaniline) were loaded, the viscosity was 3300 mPa as in Production Example 1. .s (25°C) light yellow transparent liquid. Use it as the main ingredient (2).

manufacture example 3

[0095] Except that 70 parts of Epicott epoxy resin 828, 20 parts of GOT, and 10 parts of ELM-100 (manufactured by Sumitomo Chemical Co., Ltd.; triglycidyl P-alkylaminophenol) were loaded, the viscosity was obtained as in Example 1. It is a light yellow transparent liquid at 2500mPa.s (25°C). Use it as the main ingredient (3).

Abstract

An adhesive for resin roll assembly which is to be used in such a manner that the adhesive is injected into the space between a cylindrical object made of a resin and either a roll core or a fiber-reinforced underlayer formed by winding a fibrous material impregnated with a thermosetting resin on the outer periphery of a roll core and is then gradationally cured to unite the cylindrical object to the roll core or underlayer. It comprises (a) an epoxy resin and (b) one or more amine compound hardeners (b) selected from the group consisting of aliphatic polyamines, alicyclic polyamines, heterocyclic polyamines, polyamide-polyamines having a number-average molecular weight of 800 or lower, polyether polyamines having a number-average molecular weight of 1,000 or lower, and cyanoethylated polyamines.

Description

technical field [0001] The present invention relates to resin rolls, in particular to adhesives and resin rolls for assembling rolls of papermaking calenders, and more specifically to resin-containing fiber materials injected into the core of the roll or wound on the outer peripheral surface of the core of the roll. After fiber reinforcement between the lower roll layer and the resin cylinder, it is hardened in stages to form a thermosetting adhesive and resin roller as a whole resin roller. Background technique [0002] A method of manufacturing an integral resin roller by injecting an adhesive into the roller core or between the fiber-reinforced underwrap layer and the resin cylinder body wound with a fiber material containing a thermosetting resin on the outer peripheral surface of the roller core, and hardening it to form an integral resin roller, such as It is described in JP-A-1-260092 that the process of winding a fiber material containing a thermosetting resin on the...
