Embodiment Construction

[0052] The present invention will be described in detail below with reference to the accompanying drawings.

[0053] like figure 1 As shown, the synthetic environment-friendly paper production method based on the biaxial stretching process of the present invention comprises a mixed particle granulation process and a papermaking process, and is characterized in that:

[0054] The above-mentioned mixed particle granulation process comprises the following steps: by mass fraction, weigh 75-85 parts of calcium carbonate powder, 15-25 parts of resin, 1-2.5 parts of coupling agent, lubricant with particle size of 600-1200 purpose respectively. Add 2-3.5 parts of desiccant 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 the mixture is uniform;

[0055] The above-mentioned uniformly mixed materials are added to the twin-screw granulator, and the mixed granules are granulated to complete the mixing and ex...

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 environment-friendly synthetic papermaking process and production equipment thereof, in particular to a synthetic environment-friendly paper production process and a production device thereof based on biaxial stretching with calcium carbonate powder and resin as main raw materials. 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 environmentally friendly synthetic paper, there is no water, no steam, no benzene, no formaldehyde, and no emissions. Stone powder accounts for a large proportion of the raw materials used. The products flow to the society, commonly known as stone paper. [0003] Chinese patent application CN102093632A discloses a preparation method of environmentally friendly synthetic paper, ...
