Problems solved by technology

[0005] 2. The unit weight of the product is heavy
[0009] In addition, the bullet-proof glass produced by these two methods is limited by the process conditions and structure, resulting in the production of bullet-proof glass with defects such as excessive monomer weight, low light transmittance and serious optical distortion after the product is passed.
Difficult product installation, narrow application fields and many other problems plague mid-end customers and end users

Embodiment 1

[0034] Such as figure 1 As shown, the lightweight bulletproof glass is bonded with polyurethane glue between the glass and the polycarbonate plate. The polyurethane glue is a two-component polyurethane glue, which includes: A component: polyol polymer; B component: isocyanate, The volume ratio of the two components A:B=100:65. Among them, the polyol polymer is 80% silyl polyether, 20% butanediol; the isocyanate is 3-trimethyl-5-isocyanato-1-isocyanate (base) methylcyclohexane 50% %, polyisocyanate 50%. One side of the glass bonded with polyurethane glue is coated with a layer of primer, and the primer is composed of 72% distilled water, 20% silane coupling agent, and 8% isopropanol.

[0035] The preparation method of lightweight bulletproof glass is:

[0036] First cut the PC board into the required size, then dry it at 40~60°C for 12 hours, and then place it in an environment with a relative humidity of 18~23°C and 50%RH for use; cut and grind the glass After edge molding...

Embodiment 2

[0038] Lightweight bulletproof glass, glass and polycarbonate panels are bonded with polyurethane glue, the polyurethane glue is a two-component polyurethane glue, which includes: A component: polyol polymer; B component: isocyanate, two components The volume ratio of A:B=100:70. Among them, the polyol polymer is 85% silyl polyether, butanediol 15%; the isocyanate is 3-trimethyl-5-isocyanato-1-isocyanate (base) methylcyclohexane 70 %, polyisocyanate 30%. One layer of primer is coated on one side of the glass bonded with polyurethane glue, and the primer is composed of 80% distilled water, 15% silane coupling agent, and 5% isopropanol.

[0039] Its preparation method is with embodiment 1.

Embodiment 3

[0041] Lightweight bulletproof glass, glass and polycarbonate panels are bonded with polyurethane glue, the polyurethane glue is a two-component polyurethane glue, which includes: A component: polyol polymer; B component: isocyanate, two components The volume ratio of A:B=100:75. Among them, the polyol polymer is 90% of silyl polyether, 10% of butanediol; the isocyanate is 3-trimethyl-5-isocyanato-1-isocyanate (base) methylcyclohexane %, Polyisocyanate 25%. One layer of primer is coated on one side of the glass bonded with polyurethane glue, and the primer consists of 74% distilled water, 20% silane coupling agent, and 6% isopropanol.

[0042] Its preparation method is with embodiment 1.

Abstract

The invention discloses light-weight bullet-proof glass and further provides a preparation method of the light-weight bullet-proof glass. Glass and a polycarbonate plate are glued by polyurethane glue, wherein the polyurethane glue is double-component polyurethane glue and comprises a component A, namely a polyhydric alcohol polymer, and a component B, namely isocyanate; and the volume ratio of the component A to the component B is 100 to (65-75). According to the bullet-proof glass, the double-component polyurethane glue is used for gluing the glass and the polycarbonate plate; and the defects that traditional bullet-proof glass is thick, the light transmittance is low and the like are overcome by using the flexibility and the penetration resistance of the cured polyurethane glue, and the flexibility of the polycarbonate plate, as well as the appearance cleaner than the glass and the light transmittance higher than that of the glass. The light-weight bullet-proof glass has the characteristics of light weight, small thickness, high light transmittance and the like.

Description

technical field [0001] The invention relates to special glass and its processing technology, in particular to a light bulletproof glass and its preparation method. Background technique [0002] There are two types of traditional bulletproof glass production processes: dry lamination and wet lamination. The dry interlayer uses float glass of different thicknesses, and polyvinyl butyral is bonded with glass under high temperature and pressure to form a composite glass product composed of multiple pieces of glass. The materials used in the dry interlayer process are: 1. Float glass of different thicknesses; 2. Polyvinyl butyral film (PVB); 3. Explosion-proof film. Its main process is as figure 1 shown. [0003] Main structural features: [0004] 1. More glass layers are required. The combination of glass with different thicknesses is generally not less than three layers of glass, and the thickness is currently not less than 26mm to meet the shooting requirements of the low...
