Problems solved by technology

The original synthetic paper is transparent or translucent, still retains the basic properties of plastic film, and has poor writing and printing performance
There are improved technologies, by adding porous fillers, surfactants, etc., to make synthetic paper have a whiteness and opacity similar to fiber paper, but its surface permeability is still poor, and special oil-based pens are required for writing with it. Its printing requires the use of special special inks

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing and process flow.

[0021] As shown in the figure, an equipment for patterning synthetic paper base paper according to the present invention includes a heater 3 , a primary stretching unit 4 , a secondary stretching unit 5 and a cooling device 6 . The embodiment shown in the drawings has installed two stretching units 4,5 in sequence.

[0022] The heater 3 is composed of three heating steel rollers, and the base paper is half-wound around each heating steel roller in an S-shape. The three heating steel rollers are all hollow cylinders, and the shafts at both ends are equipped with liquid inlets and outlets, and heating oil is injected into the heating roller cavity through the liquid inlets and outlets. A thermal insulation cover is arranged above the heating roller.

[0023] Auxiliary steel rolls can be set before and after the heater 3, the front auxiliary steel roll toget...

Abstract

The invention relates to a synthetic paper pattern processing method and its equipment. The invention is suitable for raw paper which is 0.1-1 mm thick and is manufactured by flow calendaring or blow molding. Through a warming mill, the raw paper is heated to the surface temperature of 50-120 DEG C and is then stretched at the stretching speed of 1-100 meter / minute. The stretching ratio is 1-5 times. The paper pattern processing equipment contains three portions, namely, a heater, a stretching apparatus and a cooling apparatus. After being stretched, cracks are generated on the surface of the synthetic raw paper and it is whitish in color, turns opaque and has no crease after being folded. In addition, writing and printing properties of the synthetic paper are similar to that of traditional fiber paper.

Description

technical field [0001] The invention relates to a synthetic paper processing method and a machine device for implementing the method. Background technique [0002] Synthetic paper is a substitute for traditional plant fiber paper and has been developed for decades. It is based on polyolefin polymer material, filled with CaCO 3 、TiO 2 Inorganic materials, such as plastic film, are processed by calendering or blow molding. Because CaCO used as filler 3 、TiO 2 Inorganic materials such as natural rocks are ground into fine powder, so the paper made is also called stone paper. The original synthetic paper is transparent or translucent, still retains the basic properties of plastic film, and has poor writing and printing performance. There are improved technologies, by adding porous fillers, surfactants, etc., to make synthetic paper have similar whiteness and opacity to fiber paper, but its surface permeability is still poor, and special oil-based pens are required for writ...
