Embodiment 1

[0026] A preparation process for a multifunctional front windshield, comprising the following steps:

[0027] 1) Ingredients: Weigh the glass substrate raw materials and grind them until the particle size is less than 0.3mm, and mix them evenly;

[0028] 2) Melting: Put the glass batch material into a pool kiln or pool furnace for heating, control the temperature at 1550 degrees, and add a defoamer at the same time to form a uniform, bubble-free liquid glass that meets the molding requirements;

[0029] 3), forming: the liquid glass in step 2) is made into a glass matrix by a float method or a calendering method;

[0030] 4), annealing: the glass substrate is annealed in the annealing furnace, and the annealing is divided into three stages, namely, the first stage of slow annealing, the second stage of rapid annealing and the third stage of normal temperature annealing, in which the first stage of slow annealing controls annealing The rate is 30 degrees per hour until the tem...

Embodiment 2

[0035] A preparation process for a multifunctional front windshield, comprising the following steps:

[0036] 1) Ingredients: Weigh the glass substrate raw materials and grind them until the particle size is less than 0.3mm, and mix them evenly;

[0037] 2) Melting: Put the glass batch material into a pool kiln or pool furnace for heating, control the temperature at 1575 degrees, and add a defoamer at the same time to form a uniform, bubble-free liquid glass that meets the molding requirements;

[0038] 3), forming: the liquid glass in step 2) is made into a glass matrix by a float method or a calendering method;

[0039] 4), annealing: the glass substrate is annealed in the annealing furnace, and the annealing is divided into three stages, namely, the first stage of slow annealing, the second stage of rapid annealing and the third stage of normal temperature annealing, in which the first stage of slow annealing controls annealing The rate is 40 degrees per hour until the tem...

Embodiment 3

[0044] A preparation process for a multifunctional front windshield, comprising the following steps:

[0045] 1) Ingredients: Weigh the glass substrate raw materials and grind them until the particle size is less than 0.3mm, and mix them evenly;

[0046] 2) Melting: Put the glass batch material into a pool kiln or pool furnace for heating, control the temperature at 1600 degrees, and add a defoamer at the same time to form a uniform, bubble-free liquid glass that meets the molding requirements;

[0047] 3), forming: the liquid glass in step 2) is made into a glass matrix by a float method or a calendering method;

[0048] 4), annealing: the glass substrate is annealed in the annealing furnace, and the annealing is divided into three stages, namely, the first stage of slow annealing, the second stage of rapid annealing and the third stage of normal temperature annealing, in which the first stage of slow annealing controls annealing The rate is 50 degrees per hour until the tem...

Abstract

The invention discloses a process for manufacturing a multifunctional front windshield. The process comprises the steps of proportioning, melting, modeling, annealing, sticking a bonding layer, sticking a reflecting layer and sticking a polarizing layer. A defoamer is added to the melting step, so that the molded glass matrix is bubble-free; the annealing is performed stage by stage, and the rate of each annealing stage is different, so that the finally manufactured windshield is high in strength and stable in performance, simultaneously has the advantages of light transmission, heat insulation, wear resistance and the like, is particularly suitable for being used as a front windshield of a vehicle body, and can keep good light transmission and stability in sun and rain for long time.

Description

technical field [0001] The invention relates to the technical field of glass materials, in particular to a preparation process for a multifunctional front windshield. Background technique [0002] The development of the appearance of modern cars is closely related to the development of glass technology. As early as 40 years ago, the front windshield of a car had adopted a single-piece curved windshield, and gradually abandoned the flat windshield. Today's car windshields are generally made into a large curved surface with a certain curvature from top to bottom, left to right. This kind of curved glass is a product with very high technical requirements no matter in terms of processing or assembly, because it involves many issues such as vehicle models, strength, heat insulation, and assembly. At present, there are many defects in the common windshield preparation process in the market, such as many product bubbles and unstable chemical properties. Contents of the inventio...
