Manufacturing technology of paper key

Abstract

The invention relates to a manufacturing technology of a paper key, which is characterized by comprising the following steps: first, selecting paper as a paper base board according to design requirements, and cutting the paper base board; second, processing the positive surface of the paper base board by selecting a printing mode or a spraying mode according to the design requirements; third, reinforcing the paper base plate manufactured in the second step, and printing the paper base board by a processing agent to form a printing layer; fourth, cutting and perforating the paper base board printed in the third step according to the design requirements; fifth, loading the paper base board obtained in the fourth step into a mould, and carrying out a single-side or double-side integral moulding technology by a silica gel layer; sixth, reinforcing a key moulded in the fifth step at hydraulic pressure; and seventh, forming a dope layer by a surface coating layer to form a finished product.The manufacturing technology of a paper key has low cost, is simple and environment-friendly, saves energy and is suitable for the field of paper key manufacture by using various kinds of paper as main materials.

Description

technical field [0001] The invention relates to a manufacturing process of keys, in particular to a manufacturing process of paper keys using paper as the main material. Background technique [0002] With the development of modern large-scale industry, all kinds of keys have been widely used in various industrial products. At present, most of the keys are made of plastic resin injection molding keycaps, and then the surface is sprayed and laser engraved, and then UV The painted keycaps are bonded to the silica gel substrate. The buttons produced by this manufacturing method are sprayed to reflect the color of the buttons, and there are the following defects: 1. It is difficult to reflect diversified colors. 2. During the spraying process, the volatile chemicals in the paint are not only harmful to the human body, but also cause serious environmental pollution, and the efficiency of the use of the paint is very low, and the paint waste is serious. 3. The buttons are made of s...

During the spraying process, the volatile chemicals in the paint are not only harmful to the human body, but also cause serious environmental pollution, and the efficiency of the paint is very low, and the paint waste is serious. 3. The buttons are made of synthetic resin, and the formed It takes a relatively long time. In order to reduce this time, it is necessary to increase the molding temperature and increase energy consumption. 4. The key material is a relatively thick synthetic resin, so there are certain restrictions on the thickness of the key. Steel sheet forming buttons, and steel sheet buttons are becoming less and less popular
