Problems solved by technology
Large-screen mobile phones meet the needs of users very well, but there are still the following shortcomings: most mobile phone screens are made of glass, and the toughness of glass is poor. When the mobile phone is accidentally dropped, the glass screen is easy to break At the same time, the price of glass is relatively high. When the screen needs to be replaced, the user needs to spend more money, which increases the user's use cost.

Embodiment Construction
[0028] A method for manufacturing a high-hardness plastic mobile phone screen or case, comprising the following steps:
[0029] (1) Secondary compression molding: First, close the injection mold and lock the first parting surface of the injection mold, and then retreat the mold clamping cylinder by 0.2mm, so that the second parting surface of the injection mold has a certain mold opening space, then inject plastic raw materials into the injection mold, the second parting surface is opened under pressure by 0.2 mm, after the injection is completed, the mold clamping cylinder advances and locks the second parting surface, and after cooling, the mold is opened to obtain a well-formed plastic substrate;
[0030] (2) Clean and dry the plastic base material for the first time with dry gas after static electricity removal, the dew point of the dry gas is -40°C;
[0031] (3), soaking for the first time: soak the plastic base material after the first cleaning and drying into the adhes...

Abstract
The invention provides a manufacturing method of a high-hardness plastic screen and a high-hardness plastic housing of a mobile phone, and a mobile phone screen and a mobile phone housing manufactured by the manufacturing method. The manufacturing method comprises the following steps: performing secondary compressing and forming to obtain a base plastic material; cleaning and drying the base plastic material through electrostatic eliminated drying gas for the first time; soaking in an adhesive for the first time; cleaning and drying the base plastic material covered with the adhesive through the electrostatic eliminated drying gas for the second time; soaking in enhanced liquid containing silicide, nanometer aluminum oxide and corundum for the second time; roasting; hardening; trimming. The product manufactured by the method is free of rainbow-like marks, high in light transmission rate, and high in density; the hardness of the product is up to 9H, and is equal to or beyond that of a traditional glass screen; in addition, the product is hard to break, so that the product can completely replace glass to be used as the screen of the mobile phone; compared with a glass material, the plastic is low in price, so that the cost of the mobile phone screen manufactured through the plastic is low, and as a result, the use cost of a user can be decreased.
Description
technical field [0001] The invention relates to the technical field of mobile phone accessories, in particular to a method for manufacturing a high-hardness plastic mobile phone screen or case and the prepared mobile phone screen or case. Background technique [0002] Nowadays, many digital products are pursuing small screens and large screens, especially in the mobile phone industry. As the size of mobile phones becomes larger and larger, the screens of mobile phones are also getting larger and larger. Large-screen mobile phones meet the needs of users very well, but there are still the following shortcomings: most mobile phone screens are made of glass, and the toughness of glass is poor. When the mobile phone is accidentally dropped, the glass screen is easy to break At the same time, the price of the glass is relatively high, and when the screen needs to be replaced, the user needs to spend more money, thereby increasing the user's use cost.
