Abstract

The invention relates to a powder cleaning-free gluing production method of laminated glass, which comprises the following steps: S1, preparing a solution of silica powder with silica powder and water and filtering the solution; S2, spraying silica powder solution on the air surface of outer plate glass and drying sprayed solution to obtain an uniform and thin silica powder layer; S3, matching the outer plate glass processed by the step S2 with inner plate glass; S4, carrying out hot bending of the glass processed by the step S3; and S5, putting a glue sheet between the two pieces of glass processed by the step S4 directly to carry out gluing. The laminated glass does not need to be cleaned in the process of the gluing; and the thin silica powder layer is absorbed by the glue sheet in thehigh-pressure process without influencing the light transmittance of the glass and can overcome the defect of cleaning the silica powder by the water in the prior art. The method at least has the advantages that: because the laminated glass is not needed to be cleaned by the water, sheet washing machines are saved and the obvious effects of energy conservation and consumption reduction are achieved; and the glass is not cleaned by the water, the existence of water stains between the glass are avoided, and problems of the quality, such as degumming, bubbles and the like are prevented.

Description

technical field

[0001] The present invention relates to a production method of laminated glass, more specifically, relates to a production method of laminated glass without clear powder gluing. Background technique

[0002] Most of the current automotive glass front shields are made of laminated glass, that is, two layers of glass are glued together by film. Laminated glass has become a mainstream of automotive safety glass, and this kind of laminated glass has gradually been widely used in other fields (such as construction, ships, locomotives, etc.).

[0003] Such as figure 1 As shown, the current ordinary laminated glass production process is: firstly inspect the glass raw material S10, then perform operations such as cutting S20, edging S30, cleaning / drying S40, and inspect whether the glass is qualified; Carry out silk screen printing / drying S50, etc.; then make silicon powder into a silicon powder solution, spray it on the air surface of the outer glass, and pair the...
