Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] Such as figure 1 Shown, the synthetic environment-friendly paper production method based on biaxial stretching process of the present invention, comprises mixed particle granulation operation and papermaking operation, is characterized in that:

[0055] The granulation process of the above-mentioned mixed particles comprises the following steps: by mass parts, respectively weigh 75-85 parts of calcium carbonate powder with a particle size of 600-1200 mesh, 15-25 parts of resin, 1-2.5 parts of coupling agent, lubricant Add 2-3.5 parts and 1-2.5 parts of desiccant to a temperature-controlled mixer, control the temperature at 40-65°C, and stir for 10 minutes until evenly mixed;

[0056] Put the uniformly mixed material into the twin-screw granulator, extrude with honey, heat cut and air-cooled, and complete the granulation of the mixed particles; among them,

Abstract

The invention discloses an environmental-friendly synthetic paper production method based on a two-way stretching process. Based on the prior art, a center pipe with a sleeve structure form is adopted on a mouth mould, a paper film is expanded and cooled by using external compressed air in a primary forming stage, and transverse stretching and stretching amplitude of the paper film in the primary forming stage are automatically regulated by using a mutual matching and cooperating function of a strutting device sleeving an inner pipe of the center pipe and an airflow, the paper film is limited by gas introduced between the paper film and the wall of a cylinder by using the cylinder arranged outside the strutting device; by adopting a series of technical means of immediately guiding a hot airflow in a paper film cylinder for being recycled by using the center pipe and improving a guide device into a roller type guide structure, compared with the prior art, the environmental-friendly synthetic paper production method has the beneficial effects that the process is simply controlled, the core process parameter of a key procedure is regulated conveniently, the product quality is stable, the production cost is low and the like.

Description

technical field [0001] The invention relates to an environmentally friendly synthetic papermaking process and its production equipment, in particular to a synthetic environmentally friendly paper production process based on bidirectional stretching with calcium carbonate powder and resin as main raw materials and a production device thereof. Background technique [0002] The R&D and application of environmentally friendly synthetic paper with calcium carbonate powder and resin as the main raw materials is developed on the basis of the production technology of plastic products. In the production process of this kind of environmentally friendly synthetic paper, no water, no steam, no benzene, no formaldehyde, no emissions, and stone powder accounts for a large proportion of the raw materials used. People call this kind of environmentally friendly synthetic paper stone paper. People commonly call stone paper products flow to the society. [0003] Chinese patent application CN1...
