Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0021] For multi-layer glass laminates, when the thickness of the laminated glass is large, the heat transfer in the middle area of ​​the film used is slow, resulting in the unmelted middle area of ​​the film, and the difficulty of venting the glued layer, resulting in more air bubbles. .

[0022] The polyurethane glue prepared by the formula of the polyurethane glue of the present application and the preparation method thereof has a small viscosity and is easy to operate. After lamination of multiple layers of glass, the adhesive layer is colorless and transparent, has strong adhesion and good environmental resistance, and solves the problem of large thickness. Glass lamination cannot use hot pressing.

Abstract

The invention relates to a formula and a preparation method of polyurethane glue, and multi-layer glass. The formula of the polyurethane glue comprises the following components in percentage by mass: 30%-50% of dicyclohexylmethane diisocyanate; 40%-60% of polytetrahydrofuran ether glycol; 0-10% of a small molecule chain extender; 0-20% of a polycaprolactone diol; 0.5-1% of an ultraviolet light absorber; 0.5-1% of an antioxidant; and 0-0.1% of a catalyst. The prepared polyurethane glue is small in viscosity, easy to operate and suitable for lamination of large-thickness glass at the room temperature, and after multiple layers of glass are laminated, the glue layer is colorless and transparent, high in adhesive strength and good in environment resistance.

Description

technical field [0001] The present application relates to the technical field of glass lamination, in particular to a polyurethane glue formulation and its preparation method, and multi-layer glass. Background technique [0002] Because the film has the advantages of good optics and excellent adhesion after hot pressing, the existing multi-layer glass is mainly laminated by hot pressing of the film, but this method is low in efficiency and high in cost, and in laminated glass When the thickness is large, the heat transfer in the middle area is slow, resulting in the unmelted middle area of ​​the film, making it difficult to vent the glued layer, resulting in more air bubbles. Contents of the invention [0003] The embodiment of the present application provides a formula of polyurethane glue and its preparation method, and multi-layer glass, which solves the problem of many bubbles in the glued layer after lamination of the existing multi-layer glass. [0004] In order to ...
