The adhesive according to the invention contains, mac. : vinyl chloride copolymer 100; AC - 66-150; organic solvent 664-1000. 1 tab.

Description

The invention relates to the chemistry of polymers, in particular, to a glue for gluing polymer films to metal surfaces, including in the manufacture of a new structural material, metal plastic.

The purpose of the invention is to increase the heat resistance of the metal, while maintaining the viability of the adhesive and strength when peeling the metal.

The invention is illustrated by the following examples.

Example 1. In the reactor, equipped with a mechanical stirrer, a reflux condenser and a thermometer, load 100 mas. a copolymer of vinyl chloride powder (90% by weight), vinyl acetate (5% by weight) and vinyl alcohol (5% by weight) was added to OHM.h.

The mixture is stirred for 1 hour at room temperature and charged with 100 parts by weight. powdered methyl methacrylate copolymer (70 wt.%) and diallyl isophthalate (30 wt.%). Stir for 3 hours at 70 ° C. Glue is obtained with a content of a mass fraction of non-volatile substances of 20%.

The method for determining the heat resistance is as follows.

Glue is applied to the degreased surface of galvanized steel, the plate is heated in a muffle furnace for 1-2 minutes to a temperature on the metal of 180-220 ° C. Then plasticized PVC film is glued to the plate with the help of rolls. Testing of metal plastics for heat resistance is carried out a day after sample preparation. Heat resistance is estimated by the distance (not more than 2 mm) by which the PVC edge of the film from the incision line at 180 ° bends 180 ° after holding the metal layer at 70 ° C for 7 hours.

The peeling strength (PVC film from metal) is measured on a Zwick universal machine with a gripping speed of 32 ± 1 mm / min.

Example 2. A reactor equipped with a mechanical stirrer, a freezing cooler and a thermometer is charged with 100 mash. Vinyl chloride copolymer powder (85% by weight), vinyl acetate (8% by weight) and vinyl alcohol (7% by weight) and 760 parts by weight of butyl acetate and 40 parts by weight were added. ethyl acetate
