A thin-walled 3D curved surface composite shell and its preparation method

Abstract

The invention discloses a thin-wall 3D curved surface composite housing. The thin-wall 3D curved surface composite housing comprises a composite plate, an internal silica gel ring, and an external silica gel ring; the bottom of the composite plate is designed to concave downward so as to form a concave part; the internal silica gel ring is arranged at the periphery of the concave part; the external silica gel ring is arranged at the periphery of the composite plate; the composite plate is composed of a PMMA layer and a PC layer via combination; the PMMA layer is arranged on the upper surface of the PC layer; the thickness of the composite plate ranges from 0.175 to 1.5mm; the thickness ratio of the PMMA layer to the PC layer is controlled to be 1: (10-4). The invention also provides a preparation method of the thin-wall 3D curved surface composite housing. The external part of the thin-wall 3D curved surface composite housing is high in brightness, is transparent, is colorful, and possesses decorative effect; problems such as glass material poor toughness and fragility are solved; structural member compact resistance, anti-break performance, and durability are achieved; the surfacehardness is high; the whole strength is high; and the structure is stable and reliable.

Description

technical field [0001] The invention relates to a glass shell, in particular to a thin-walled 3D curved composite shell and a preparation method thereof. Background technique [0002] Glass casings and related products are deeply loved by people because of their good transparency, hard texture, stylish appearance, clear and bright, and high-end appearance. They are also more and more used in handicrafts, consumer electronics, fashion products, etc. value-added products. However, due to the difficult processing of glass materials, easy breakage, high specific gravity, low product precision, and high production costs, the application range is narrow. Finely crafted glass products can only be used for high-end luxury jewelry or handicrafts, and it is difficult to mass-produce them. manufacture. [0003] At the same time, with the improvement of people's living standards, the requirements for portable 3C electronic products such as high-value-added wearable devices, mobile pho...

Problems solved by technology

[0006] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a thin-walled 3D curved composite shell, which has a bright, high-gloss, and transparent appearance and is more gorgeous and colorful. The colorful appearance decoration effect can solve the problem of poor toughness and easy breakage of glass materials, and realize the anti-collision, anti-fall and durable characteristics of structural parts, and has high surface hardness, good overall strength, and stable and reliable structure.
