Problems solved by technology

[0003] There are generally two types of existing bulletproof glass: PVB bulletproof glass and organic material composite glass. They are composited into a transparent whole. This composite glass has good impact resistance, optical performance and weather resistance, and the cost is relatively low, but when the bullet passes through the glass, it will produce splashes and cause damage to the human body; organic material composite Glass is glass and polycarbonate plate bonded by polyurethane film to form bulletproof glass. This kind of glass is lighter than bulletproof glass, less likely to produce splashes, and has better bulletproof ability. However, since polycarbonate is an organic material, its The rigidity is not as good as that of glass, so its surface is easy to scratch, its optical properties are not easy to control, its radiation resistance is poor, and its cost is relatively high, which limits its application

preparation example 1

[0034]Preparation 1: Under the conditions of 100-110 ° C, the vacuum is 0.09 MPa, then dried 50 kg of dry polytetrahydrofuranol, isocyanate 8kg, and Two Fluoanic acid. After 1 kg of ethyl acetate was dissolved in 100 kg of ethyl acetate, it was reacted at a temperature of 85 ° C for 3 h; then 1,6-hexanediol diacrylate 5 kg, 1 kg of dihydroxymethyl propionate, hydroxyethyl acrylate 1 kg reaction After 3 h; After cooling to 50 ° C, 0.1 kg of polydimethylsiloxane, 0.05 kg of titanium dioxide was added, and the polyurethane adhesive can be obtained at 600 r / min at a rate of 600 r / min.

preparation example 2

[0035]Preparation 2: Under the conditions of 105 ° C, the vacuum is 0.1 MPa, then dried 1.5H; then the dried polytetrahydrofuranol is 52.5 kg, the isophorone diisocyanate 9kg and the second month After dissolving in 110 kg of ethyl acetate, butyl tin is dissolved, then 1,6-hexinate 5.5 kg, 1.5 kg of dihydroxymethyl propionic acid, hydroxyethyl acrylate, and hydroxyethylene acrylate is then added to the temperature of 87.5 ° C; The ester 2 kg was reacted for 3.5 h; after cooling to 55 ° C, 0.15 kg of polydimethylsiloxane, 0.06 kg of titanium dioxide was added, and the polyurethane adhesive can be obtained at 600 r / min at a rate of 600 r / min.

preparation example 3

[0036]Preparation Example 3: Under the conditions of 105 ° C, the vacuum is 0.11 MPa, then dried 55 kg, the dried polytetrahydrofuranol 55 kg, isophorone diisocyanate 10kg and Dikuttinikin Tin 0.3 Kg was dissolved in 120 kg of ethyl acetate, reacted at 90 ° C at a temperature of 90 ° C for 4 h; then 1,6-hexanediol diacrylate 6 kg, 2 kg of dihydroxymethyl propionate, hydroxyethyl acrylate 3 kg reaction for 4 h; After the temperature eliminating to 60 ° C, 0.2 kg of polydimethylsiloxane, 0.07 kg of titanium dioxide, stirred at a rate of 600 r / min for 10-20 min, i.e., a polyurethane adhesive.

Abstract

The invention discloses a bulletproof composite glass and a preparation method thereof. The key point of the technical solution is a bulletproof composite glass, which comprises a first glass layer, a first PVB layer, a second glass layer, a second PVB layer, third glass layer and safety protection layer; the thickness of the first glass layer, second glass layer and third glass layer is 8mm; the thickness of the first PVB layer and the second PVB layer is 1.52mm; safety protection layer It is a polycarbonate plate with a thickness of 2mm; the safety protective layer and the third glass layer are bonded by a polyurethane adhesive with a thickness of 0.5mm; the invention can strengthen the polycarbonate plate through the polyurethane adhesive with high cohesive force. The bonding force between ester board and inorganic glass, the adhesive layer formed by polyurethane adhesive can absorb ultraviolet rays, improve the radiation resistance of polycarbonate, reduce the yellowing and aging of polycarbonate, improve the transparency of bulletproof glass, and prolong the bulletproof The service life of the glass.

Description

Technical field[0001]The present invention relates to the field of glass processing, and more particularly, it involves a bulletproof composite glass and a preparation method thereof.Background technique[0002]Bomb glass refers to a transparent material having a high degree of light-oriented ability, and has a certain bullet-aged ability; the bulletproof principle is that the impact kinetic energy of the bullet into glass into a glass elastic potential energy and broken surface, thus reaching bulletproof. purpose.[0003]Existing bulletproof glass generally has two: PVB bulletproof glass and organic material composite glass, PVB bulletproof glass is a polyvinyl butyral (PVB) bond between multilayer float glass, after high temperature and high pressure, They composite into a transparent whole, which has good impact resistance, optical properties, weather resistance, low cost, but when bullets pass through the glass, it will cause damage to the human body; organic material composite Glas...
