Problems solved by technology

This process is time-consuming and labor-intensive, the material cost is high, and the final bond strength is not high; and it is not easy to realize automatic assembly
[0003] In CN201209938, it is disclosed that the special glass panel for air conditioners does not need to use double-sided pressure-sensitive adhesive tape due to the U-shaped groove structure, but this clamping structure is difficult to have airtightness

Embodiment 1

[0130] Referring now to Figure 1, it shows a laminate according to one embodiment of the present invention, which is a glass panel, wherein the first layer 1 is a plastic bottom frame, the second layer 2 is a glass plate, the first layer 1 and A first adhesive area 3 formed by hot-melt pressure-sensitive adhesive and a second adhesive area 4 formed by reactive polyurethane hot-melt adhesive are arranged between the second layer 2 . The size of the glass panel is 43cm long, 26cm wide, 4mm thick, and a curvature of 15mm; the size of the plastic bottom frame is 43cm long, 26cm wide, and 3mm thick, with a curvature of 10 to 15mm, which is prone to deformation due to storage and transportation. SG6820 and TEP6830 were first coated on the bottom frame at the same time, among which SG6820 and TEP6830 were 10g / m:4g / m respectively, and the thickness was 0.4mm. Then press the bottom frame and glass together for 30 seconds at 0.3MPa. The resulting laminate was tested and found to pass a...

Embodiment 2

[0132] Carry out experiment with reference to reference example 1, difference is that the gluing amount of SG6820 and TEP6830 is respectively 12g / m: 2g / m. The resulting laminate was tested and found to pass all tests, and the test results obtained are listed in Table 2 below.

Embodiment 3

[0134] The experiment was carried out with reference to Reference Example 1, except that SG9220 was used instead of SG6820. The resulting laminate was tested and found to pass all tests and the test results are listed in Table 2 below.

Abstract

The invention relates to a laminated piece which is obtained by combining at least two kinds of binding materials and a preparation method thereof. The laminated piece comprises the following components: a first layer containing a first surface and a second surface; a second layer containing a first surface and a second surface, wherein the first surface of the second layer faces toward the first surface of the first layer; and a bonding zone which is located between the first surface of the first layer and the first surface of the second layer and is formed by at least two kinds of binding materials. The laminated piece has a stable structure, and is suitable household electrical appliances, such as air-conditioning, refrigerator, washing machine, microwave oven, etc. The laminated piece has excellent initial strength and final binding strength, and is especially suitable for rapid and automatic assembly lines, so that production efficiency is improved, and at the same time labor and material cost are saved.

Description

technical field [0001] The present invention relates to laminates and methods for their preparation. More specifically, the present invention relates to laminates obtained by combining at least two adhesive materials and methods for their preparation. Background technique [0002] Double-sided pressure-sensitive tapes are widely used in the current industrial assembly of glass panels. CN102869499A describes its typical process, first tear off one side of the release paper, stick the tape on the first base material such as the bottom frame, then tear off the release paper on the second side, and finally press it with the second base material such as glass. This process is time-consuming and labor-intensive, the cost of materials is high, and the final bonding strength is not high; and it is not easy to realize automatic assembly. [0003] CN201209938 discloses that the special glass panel for air conditioners does not need to use double-sided pressure-sensitive adhesive tap...
