Embodiment 1

[0056] Preparation of LOW-E coated laminated glass, final products such as figure 1 As shown, from top to bottom are the first glass substrate 1 , the interlayer interlayer film 3 , the second glass substrate 2 and the PVC protective film 4 .

[0057] Specific steps include:

[0058] Step 1. Prepare 2 float glass substrates with a thickness of 12 mm. The 2 glass substrates are the first glass substrate 1 and the second glass substrate 2 from top to bottom; The sheet 2 is cleaned and dried, and the bottom of the second glass substrate 2 is processed by vacuum magnetron sputtering LOW-E coating;

[0059] Step 2. The first glass substrate 1 is cleaned and dried, and the first glass substrate 1 is laminated on the top of the second glass substrate 2 obtained in the step 1, and the interlayer film is interlayered. The material of 3 is common transparent PVB (polyvinyl butyral resin), obtains the first crude product of glass;

[0060] Step 3. In the first glass crude product obta...

Embodiment 2

[0067] Preparation of LOW-E coated laminated glass, final products such as image 3 As shown, from top to bottom are the first glass substrate 1, the interlayer interlayer film 3, the second glass substrate 2, the interlayer interlayer film 3, the third glass substrate 5, the interlayer interlayer film 3, and the fourth glass substrate 6 and PVC protective film4.

[0068] The specific steps include the following:

[0069] Step 1. Prepare 4 heat-strengthened flat glass substrates with a thickness of 15 mm. The 4 glass substrates are the first glass substrate 1, the second glass substrate 2, and the third glass substrate 5 from top to bottom. and the fourth glass substrate 6; the fourth glass substrate 6 is cleaned and dried, and the bottom of the fourth glass substrate 6 is processed by vacuum magnetron sputtering LOW-E coating;

[0070] Step 2. Clean and dry the first glass substrate 1, the second glass substrate 2 and the third glass substrate 5, and sequentially clean the ...

Embodiment 3

[0078] Preparation of LOW-E coated laminated glass

[0079] Step 1. Prepare three glazed glass substrates with a thickness of 6 mm. The three glass substrates are the first glass substrate 1, the second glass substrate 2 and the third glass substrate 5 from top to bottom; The third glass substrate 5 is cleaned and dried, and the bottom of the third glass substrate 5 is processed by vacuum magnetron sputtering LOW-E coating;

[0080] Step 2. Clean and dry the first glass substrate 1 and the second glass substrate 2, and clean the second glass substrate 2 and the second glass substrate 5 on top of the third glass substrate 5 obtained in the step 1. A glass substrate 1 is subjected to interlayer lamination processing, the material of the interlayer interlayer film 3 is SGP, and the first crude glass product is obtained;

[0081] Step 3. In the first glass crude product obtained in the step 2, the bottom of the third glass substrate 5 is pasted with a 0.03mm thick PVC protective ...

Abstract

The invention relates to LOW-E coated laminated glass, hollow glass and a preparation method of the LOW-E coated laminated glass and the hollow glass. The preparation method comprises the following steps: step 1, preparing n glass substrates, namely the first glass substrate to the nth glass substrate, in sequence from top to bottom; performing vacuum magnetron sputtering LOWE coating processing treatment on the bottom of the nth glass substrate; 2, sequentially carrying out interlayer laminating processing treatment on from the n-1th glass substrate to the first glass substrate at the top ofthe nth glass substrate obtained in the step 1; 3, pasting a PVC protective film at the bottom of the nth glass substrate; then, heating and rolling the first glass crude product twice in sequence ina two-stage interlayer roller press; and 4, placing the crude glass product obtained in the step 3 in a reaction kettle, and carrying out pressurization and heating treatment to obtain the LOWE coatedlaminated glass. The preparation method provided by the invention is simple to operate, and can effectively improve the yield of LOW-E coated laminated glass products and the total production efficiency.

Description

technical field [0001] The invention relates to the technical field of preparation of energy-saving glass, in particular to a Low-E coated laminated glass, hollow glass and a preparation method thereof. Background technique [0002] LOW-E glass has the characteristics of low heat transfer coefficient and infrared reflection. Its main function is to reduce the radiant energy transfer of indoor and outdoor far-infrared rays, and allow solar radiation to enter the room as much as possible, thereby maintaining the indoor temperature and saving heating and air conditioning costs. LOW-E glass is widely used in large public buildings, ordinary public buildings, medium and high-end residences, ordinary residential buildings, etc. [0003] Laminated glass is a kind of safety glass with excellent performance. Its processing method is to use one or more layers of PVB film, SGP film (ionic interlayer film), EVA, etc. between two or more pieces of glass. After a certain period of time,...
