[0028] 2. Preparation method of epoxy resin adhesive for sandpaper

[0029] The epoxy resin adhesive for sandpaper is prepared by mixing components A, B and C, and the composition of components A, B and C is the same as above. The preparation method of epoxy resin adhesive for sandpaper is as follows, and its preparation step comprises:

[0030] (1) Preparation of component A: Pour 67-80% of epoxy resin and 20-33% of diluent into the reaction kettle in turn, and stir while pouring, and mix evenly.

[0031] (2) Preparation of component B: Pour 50-80% of curing agent and 20-50% of toughening agent into the reaction kettle in sequence, and stir while pouring, and mix evenly.

[0032] (3) Mixing and preparation: Firstly, the prepared A and B components are mixed and prepared at a ratio of 100:7 to 120 by weight, and then the third component is added to a ratio of 25 to 60 by weight, and the mixture is evenly stirred to obtain the epoxy resin for sandpaper. Resin binder.

Abstract

An epoxy resin adhesive for abrasive paper is prepared from the component A composed of epoxy resin and diluent, the component B consisting of solidifying agent and toughening agent and the component C which is solvent through proportionally mixing component A with B, stirring, proportionally adding component C and stirring.

Description

technical field [0001] The invention relates to the field of materials, in particular to an epoxy resin adhesive for sandpaper and a preparation method thereof. Background technique [0002] Sandpaper has been widely used in many industries because of its various specifications and low price. At present, alkyd varnish, amino resin paint, etc. are mainly used as the binder of sandpaper. Due to the defects of low bonding strength and poor heat resistance of these resins, when the sandpaper is polished, it is easy to fall off the sand grains, resulting in grinding efficiency. lower question. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an epoxy resin adhesive for sandpaper and a preparation method thereof. The epoxy resin adhesive has excellent bonding performance, thereby being able to overcome the problems existing in the current alkyd resin and the like, and can also improve the brittleness of epoxy.
