spoon, then covered with a separating layer, followed by polymerization at 120 ° C for 25 minutes.
After polymerization, the resulting film is peeled off the substrate. It is used to make multi-layered glasses.
The mechanical properties of laminated glasses manufactured using the film of Example 1 are determined as follows.
The film is placed on a layer of silicate glass with a thickness of 2.6 mm. The connection of the two layers is carried out in two stages: the compound is preliminarily pressed between the two rollers of the rolling machine, and then the obtained double-layer glass is placed in an autoclave, which is kept for 10 hours under a pressure of 10 bar and at -135 ° C.
The resulting double-layered glass is absolutely transparent.
The adhesion between the silicate-I o glass layer and the polyurethane film is defined as follows.
A 5 cm wide strip is cut out of double-layer glass. One end of this strip is fixed and pulled in a direction perpendicular to the surface of the glass at a speed of 5 cm per minute. The test is carried out at 20 ° C. The average tractive effort required to strip the strip is recorded. This value is 10 daN / 5 cm.
Impact resistance tests at various temperatures are also carried out.
The first impact strength test is carried out with a steel ball weighing 0.260 kg (a test with a heavy ball), which falls on the central part of the sample, having a square shape with a side of 30.5 cm and installed in a rigid frame. The drop height is approximately measured, at which 90% of the samples are not penetrated through the ball.
one
For the double-layer glass obtained in Example 1, this height is 12 m.
A second impact strength test is conducted with a steel ball weighing 0.227 kg and a diameter of 38 mm (light ball test) at -20 ° C and the results are 12 and 11 meters respectively.

The scratch resistance of the double-layer glass 32-g.
The scratch resistance is measured by a test carried out using an Eriksen type 413 instrument. The load on the diamond head is measured to obtain a scratch in a film connected to a glass substrate.
After abrasive treatment, the film shows a transparency deviation of 0.94%.
Abrasion resistance is measured according to European standard P42. A sample of the abrasive treatment with an abrasive wheel after 100 vol, the abrasive wheel is measured using a spectrophotometer, the transparency of the part treated with the abrasive wheel and the untreated part. The deviation of this value is judged on resistance to wear.

Two-layer glass, manufactured using the film of example 2, has the following mechanical properties: 11 daN / 5 cm adhesion; 11 m durability for dough with a ball, 13.5 m and 13.5 m for dough and 40 ° С
