Description

The method of obtaining splinter glass such as Triplex.

It was filed on August 4, 1936, No. 198875. Published June 30, 1937.

Significant otiac.trocTb ooiiiiHoro is one; 1. when used in automotive and automotive industry, especially in connection with the rapid increase in speeds in automotive and domestic transport. : ata the Persian technique. Attempting the safeguarding of a bezasnochnogo shatterproof glass stack 1a tnna Triplex.

Ra; The development of the automotive and aerospace industry requires that NromyshleiStat produce significant quantities of millions of square meters. B1) High quality (of this broken glass, having a high degree of splitting and lightness, as well as maximum light fastness and projection) accuracy.

The currently used method is to prepare glassless glass by basing glass and cellulose using gelatin and gluing10) composition that includes a compounding acetic acid, which is a synthetic solvent for cellonidum and. conditions of the sc.hepwapi process.

. The methods of making shatterproof glass to the formulations of adhesives used for these methods have a number of significant drawbacks, which lead to

b (broken glass is obtained of poor quality, both in terms of its splinterless and (especially) in terms of its light resistance.

The main main defoisers of shatterproof glass manufactured by existing methods are nv. It is insufficient in light resistance to sunlight and daylight, i.e., its rapid light. The phenomenon of yellowing under the action of light, voob1I1, is inevitable for all products, in the composition of which there is a nitrocellulose, and oprasd .: iriroda itself 11th the last one. However,;) This process of nitrocellular degradation is accelerated in the presence of it and a number of substances - in particular, acids and. on the contrary, this process to a certain extent can be slowed down (;) 1 by excluding from the composition of the objects containing s and the cellular cellular tissue of all agents. accelerate this decay.

In particular, for glassless glass, such a harmful substance that is part of the bonding composition is acetic acid, which significantly accelerates the process of decomposition of celluloid I non-scratch glass.

Comparatively irradiated with a mercury-quartz lamp oor; 5Csb o.kol glass, prepared by spmie with acetic acid cc; It showed that the light stability of the samples obtained with the neutral gluing method was found on the peso punostom. As for the adhesion sticking, i.e., glass-free glass, the authors of the present invention succeeded in establishing that acetic acid can be successfully replaced by a number of organic preparations, HMeiOHiHX neutral. such as complex sniffy-efnrov. possessing (in pure form or with a content of a small percentage of water, dissolve the swelling of both the gelatin and the celluloid), diglycol. diglycol monoacetne, diglycol diacetate. myoethleplol, monomethyldiglycol. monometrglksern, dnmetilglitzernn. monoacetinglycerim, diacetngliderin, etc.

On the basis of this, 1) azrabot1 method and obtained shatterproof glass with a nrimopenem of any of the above methods into the retinent |) e gluing compositions without using acetic acid or any other acid.

The proposed method for the production of beskolkochnogo glass is as follows:

a) any of the (listed HevecTB veins or a mixture of these substances is introduced into the composition of water) of an o-gelaty solution applied to the glass, while the celluloid is not treated at all;

b) a siRT solution of as-loooo nz of lerechslennyh of the properties or a mixture of these properties is applied to the celluloid. The glass also contains a gelatinous water solution;

c) glass and celluloid are dried at 30 --- 6O before zero removal of both water and diluents, which are then assembled into quilts and filled with an autoclave of 80-100 nr at a pressure of 10-WATM. (: 10-50 min.

This method of gluing, giving a shatterproof glass of high light resistance, greatly simplifies the whole technological H1) process. as a result of application instead of double - single spraying, as well as due to a simpler thermal regime of sup1ka collototoda sh.ge lubricant.

The reduced technological process of the R part of the 1n hulverization makes it possible to obtain a glass without scrap and of a high purity, since with a shorter amount of dust after the inversion decreases (the possibility of nonadhesive inclusions and dust on the surfaces to be glued is reduced).

This method; It can be implemented at any of the Jta shatterproof glass factories with existing equipment, without any alterations of it, with a highly simplified design and production scheme. the possibility of increasing the productivity of the equipment and with the convenience of ud (the value of the output product.
