Adhesive, reflecting film, pad pasting glass or slice brick containing the adhesive

Abstract

The invention discloses adhesive and reflective film, filmed glass and a split brick containing the adhesive. According to the weight parts, the adhesive comprises 100 parts of epoxy resin, 50 parts of anti-yellowing epoxy resin, 75 parts to 120 parts of rock powder higher than 600 meshes and 1 part to 6 parts of cellulose (HPMC). The reflective film is formed by scratching the adhesive on the back surface of the reflective film without gum. The filmed glass provided by the invention comprises glass and the reflective film without gum, wherein, the front face of the reflective film without gum is pasted on the glass, and the back surface of the reflective film without gum is scratched with the adhesive. The adhesive has the advantages of strong cohesive force, strong density, aging resistant and good barrier property, simultaneously, the adhesive has good repairing and leveling functions which can effectively make up for the defects of the pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to a safety warning material and a decoration material, in particular to a reflective film, a filmed glass or a tile, and an adhesive glue used on the retroreflective sign glass, the reflective film or the tile. Background technique [0002] Reflective film is a main variety of retroreflective materials popular in the market at present. Reflective film plays an important role in the warning signs of road traffic safety facilities. This kind of reflective film mainly uses plastic film as the carrier, and a A mixture of layer glue and aluminum-based silver powder to form a reflective material layer, and then coated with a layer of glass beads with a refraction effect and various colors to form a reflective film. According to the retroreflection performance of the product, the performance of the reflective film in the GB / T 18833-2002 "Reflective Film for Highway Traffic Signs" of the People's Republic of China is divided into Class I...

AI Technical Summary

Problems solved by technology

At present, the adhesive----pressure-sensitive adhesive used in the reflective film has a short service life when applied on the cured outdoor uncovered cement mortar substrate (it is slightly better when applied on the dry cement mortar substrate), the main reason is The water resistance or impermeability of the pressure-sensitive adhesive is not good. At the same time, the pressure-sensitive adhesive cannot be pasted or not firmly pasted on the substrate with uneven or rough surface.
