The invention relates to a composition for the manufacture of a sheet that can be used to obtain a laminated glass, consisting of a single layer of silicate glass and at least one layer of plastic and intended, for example, to be used as a windshield. The aim of the invention is to improve the optical quality of the laminated glass.

It can be stored or used directly to make multilayer glass. The mechanical properties of laminated glasses manufactured using the film of Example 1 are determined as follows. The film is placed on a glass thickness of 256 mm. The connection of the two layers is carried out in two stages. During the first stage, the preliminary connection is made by passing the 1-compound between the two rollers of the rolling machine, during the second stage, c1, the obtained two-layer glass is placed in an autoclave, where it is held for about 1 hour under pressure. about 10 bar and at about 135 ° C. The resulting two-layer glass is completely transparent, The adhesion between the glass layers and the polyurethane film is determined in the following way: A 2 cm thick goirin band is drawn out of a two-layer glass. One end of this band is fixed and pulled in a direction perpendicular to the surface of the glass at a speed of 5 cm / mitg. The test is carried out at about. The value of the average pull force is recorded, neo for the separation of the stripe. This value is 10 daN / 5 cMo. Testing for impact strength at different temperatures is also carried out. The first test for impact resistance is carried out with a steel ball weighing 2.260 kg (test with a heavy ball), which falls on the central part of the sample, which forms the shape of a square with a side of 30J5 cm and fixed in a rigid frame. The height of the p, 1 day is measured approximately. At KOTOpoii, 90% of the samples are not punched by the ball. five 0 5 n Q g 5 5 0 through LL of double-layer glass, obtained in the described manner, this height is 12 m. The second test for impact strength is carried out with a steel ball weighing 0.227 kg and 38 mm in diameter (test with a light ball). One test is carried out at a temperature of - 20 ° C, and the second at a temperature of 40 ° C. The obtained results are 12 and 11 m, respectively. The resistance of the double layer glass is 32 g. After the abrasive of the 1st treatment, the film shows a transparency deviation of 0.94%. The scratch resistance is determined as follows: the magnitude of the load on the diamond head needed to produce a scratch in a film connected to a glass substrate is measured. Abrasion resistance is measured according to European standard P42. For this purpose, the sample is subjected to an abrasive treatment with an abrasive aid. After 100% of the abrasive wheel, the deviation of transparency with the abrasive part treated with the abrasive circle and the untreated part is measured using a spectrophotometer.
