Production technology of gold-added applique melamine dishware

Abstract

The invention discloses a production method of gold-added applique melamine dishware. The production method is realized by the following steps: firstly, forming of melamine initial product; secondly applique; thirdly, placing the melamine dishware after applique into a mould to be pressurized; fourthly, slightly opening the mould to discharge gas produced in pressurization; fifthly, closing the mould for pressurization after gas discharge, thus obtaining applique product; sixthly, opening the mould and adding gold into the inner wall or outer wall of the applique melamine dishware; seventhly, placing the product after adding gold into the mould for pressurization; eighthly, slighting opening the mould to discharge the gas produced in pressurization; ninthly, closing the mould for pressurization after gas discharge and opening the mould to obtain the gold-added melamine dishware. The invention has the beneficial effects that: by control of temperature of the mould and pressure in production process, production raw material reacts, thus meeting product technology design requirement; by control of discharge time of gas produced in processing process, the gas produced in the processing process is discharged fully; and harm to health of user produced by the product when in use is avoided, thus ensuring that safe and environmentally friendly applique (gold) melamine dishware is produced.

Description

technical field [0001] The invention relates to a production method of gold melamine tableware with decals. Background technique [0002] The production of melamine tableware at home and abroad has a history of several decades. The principle of producing melamine tableware is basically to heat the melamine raw material under a certain temperature and pressure to make it undergo polycondensation reaction. its molding. For the application of the principle in the processing process, due to the influence of raw materials, heating (pre)heating temperature, pressure, exhaust time, curing time and other factors, the safety and environmental protection performance of the produced melamine tableware is affected. For example, the article "Melamine Plastic Tableware Molding Process and Mold" published in the "Plastic Science and Technology" published by Yang Kelong of Dalian Plastics Research Institute in August 2003, No. 4 (No. 156), gave the general melamine plastic tableware moldin...

Problems solved by technology

For example, the article "Melamine Plastic Tableware Molding Process and Mold" published in the "Plastic Science and Technology" published by Yang Kelong of Dalian Plastics Research Institute in August 2003, No. 4 (No. 156), gave the general melamine plastic tableware molding process. Due to the temperature and exhaust time of the important processes that have an important impact on safety and environmental protection, the definite quantity is not fully given and the decal and gold process is not given, which makes the production of safe and environmentally friendly decal and gold melamine tableware difficult.
