METHOD FOR LAP SPLICING COMPONENTS MADE OF FIBRE-GLASS Russian patent published in 2014 - IPC C09J5/02 

FIELD: chemistry.

SUBSTANCE: in the method for lap splicing components made of fibre-glass by applying an adhesive on the surfaces to be glued and contacting the surfaces, an adhesive based on a solution of chlorinated polyvinylchloride resin CPVC in an organic solvent is applied twice. The solvent is a mixture of butyl acetate and acetone in ratio of 1:1. Further, the method includes adding a modifier of a phosphorus-, boron- and nitrogen-containing oligomer, which is obtained in advance by reacting methyl phosphite borate, epoxy resin ED-20 and aniline in weight ratio 2.5:1:2.5, in amount of 0.1-10.0 pts.wt per 100 pts.wt adhesive. The adhesive film is dried at room temperature - the first layer for 10 minutes and the second layer for 1 minute.

EFFECT: invention simplifies the method of gluing components made of fibre-glass and increases the strength of lap splicing fibre-glass.
