Embodiment Construction

[0045] The environment-friendly stone paper of the present invention and its preparation method will be further described in detail below through specific implementation examples.

[0046] A kind of environment-friendly stone paper, it is made through the following steps:

[0047] 1) Remove impurities from waste plastics, crush and dry until the moisture content is 3‰ for later use;

[0048] 2) Remove impurities from waste paper, crush and dry until the moisture content is 3‰ for later use;

[0049] 3) Hot mixing: Add the waste paper of the formula into the hot mixing device, stir at a low speed at a temperature of 100-110°C, and then add coupling agent, compatibilizer, dispersant, internal lubricant, external lubricant, Flame retardant, high-speed stirring, then adding waste plastics and high-speed stirring; the thermal mixing device is a vertical mixer, the speed of high-speed stirring is 150-200r / min, the time is 3min, and the speed of low-speed stirring is 50-80r / min, Th...

Abstract

The invention discloses environment-friendly stone paper and a preparation method thereof. The environment-friendly stone paper is prepared by the following components by weight: 60-70% of waste plastic, 22-30% of waste paper, 1-2% of a coupling agent, 0.5-1% of compatilizer, 0.5-1% of dispersant, 0.5-1% of internal lubricant, 0.5-1% of external lubricant, 1-2% of fire retardant and 2-3% of an ultramicro foaming agent, and the preparation method comprises the steps of removing impurities, drying, mixing thermally, mixing in a cold manner, granulating, and molding. The stone paper provided by the invention is good in physical and mechanical performances, and uses waste plastic and waste paper as main raw materials, thereby saving resources and energy, and reducing emission, and a new road for development of the stone paper is also provided.

Description

technical field [0001] The invention relates to the technical field of stone paper, in particular to an environment-friendly stone paper prepared from waste plastics and waste paper and a preparation method thereof. Background technique [0002] Paper is one of the four great inventions in ancient China. It is made of plant fibers, and the main raw material is wood pulp made of wood. For this reason, a large number of natural forests are cut down every year. Under the background of national forestry protection and logging ban, the sources of raw materials for traditional papermaking have been restricted. In addition, traditional paper produces a large amount of waste water in the production process, which seriously pollutes the environment. In addition, it is not resistant to moisture, not waterproof, afraid of corrosion, insects, large dimensional deformation, and poor physical and mechanical properties. It has been unable to meet the requirements of many fields. [0003]...
