Production technology for non-woven-fabric dining table pad

Abstract

The invention discloses a production technology for a non-woven-fabric dining table pad. The production technology includes the following steps of firstly, material preparing, wherein 40% of PE 7042, 10% of PP T30s, 36% of heavy calcium carbonate, 9% of PE wax, 3% of stearic acid zinc salt and 2% of coupling agent are prepared into a mixture; secondly, mixing, wherein the mixture runs and is stirred to be even in a high-speed stirrer; thirdly, melting extrusion, wherein the mixture is sent to a melting extrusion machine, the temperature is progressively controlled to be 170 DEG C to 220 DEG C, and the mixture is melted, extruded and pulled into a piece; fourthly, showering synthesizing and shaping, wherein the pulling piece passes through a shaping cooling roller, a BOPP flower printing membrane is padded to the front of the pulling piece, non-woven fabric is padded to the back of the pulling piece, the three layers are extruded and shaped through the shaping cooling roller, and a finished product is formed after winding. The non-woven-fabric dining table pad does not need to be covered, titanium dioxide is omitted, overturning, warping and shifting are not prone to occurrence, and the material is flexible, sanitary, nontoxic, easy to decompose, capable of being recycled and more environmentally friendly.

Description

technical field [0001] The invention relates to a production method of tableware, in particular to a production process of a non-woven table mat. Background technique [0002] The middle layer of the existing table mat is generally formed by melting and co-extruding the general-purpose PP+PE plastic through an extruder (also called an extruder). Due to the material composition of the middle layer, only PP+PE Composed of plastic, the finished product is relatively light, and the cost is relatively high. Because the above-mentioned materials are thin and transparent, the patterns on the upper and lower sides affect each other, so that the overall picture appears unclear and disorderly. More importantly, due to the thin and light material, the table mat is often easy to roll, twist, or even shift after it is placed on the table during use, which brings a lot of inconvenience to use. Therefore, need to redesign and improve the production method of place mat. Contents of the i...
