Abstract

The invention discloses lightweight stone paper and relates to synthetic paper. The lightweight stone paper is composed of a base paper layer and a coating layer; the coating layer is coated on the base paper layer; the base paper layer consists of the following components by weight part: 15-30 parts of synthetic resin and 70-85 parts of mixed materials. The synthetic resin is polylactic acid, or EVA (ethylene vinyl acetate), or PP (polypropylene) or PE (polyethylene) or combination of any two of polylactic acid, EVA, PP or PE; the mixed material is sawdust, or bamboo chips or combination of sawdust and bamboo chips; the ingredient of the coating layer comprises the following ingredients by weight part: 20-40 parts of acrylic resin, 20-40 parts of lithopone and 30-50 parts of deionized water. The lightweight stone paper has the beneficial effects that the mixed material is light in weight and good in dispersibility because the mixed material is sawdust, or bamboo chips or the combination of the saw dust and the bamboo chips, and the lithopone has good covering property, thereby conveniently reducing the weight of the paper, improving the quality of the paper and reducing the manufacture cost.

Description

A kind of lightweight stone paper
Technical field
The present invention relates to stone paper, refer to a kind of lightweight stone paper especially.
Background technology
The demand and the consumption figure of paper product constantly increase, and this is relevant with improving constantly of the progress of social civilization and human living standard.The tradition paper technology has following deficiency at least: 1, the main raw material of papermaking is the wood pulp that trees are processed, and paper industry has consumed a large amount of valuable forest resources, is a key factor that causes earth ecology unbalance.2, paper industry also consumes the great amount of water resources and the energy.3, wet production is adopted in the production of various paper mostly; Produce paper pulp through a series of chemical method and physical method, discharge a large amount of acid, alkali wasteliquid, contaminated soil and water body; The environment that the mankind are depended on for existence suffers to destroy and threatens; And the processing up to standard of acid, alkali wasteliquid is needed the labor input, difficulty of governance is big, causes production cost to improve.4, production method is complicated, and equipment investment is big.
Whole world environmental issue is more and more outstanding, and the forest reserves constantly reduce, and traditional paper and manufacturing technology thereof have been proposed challenge.The synthetic paper of stone paper and so on arises at the historic moment, and is applied to all trades and professions.But the stone paper of producing at present is heavier than conventional paper, thereby the application of stone paper is limited to.Cause the heavy reason of stone paper more; One of them is that stone paper is a main raw material with artificial resin and Paris white; The proportion of Paris white (comprising heavy calcium carbonate and precipitated calcium carbonate powder) is bigger, and Paris white generally accounts for about 75%, causes stone paper proportion to increase.
Summary of the invention
The present invention is intended to the above-mentioned deficiency to traditional paper technology and present stone paper, and a kind of lightweight stone paper is provided, and its proportion is near traditional paper, and combination property is superior, generally is suitable for or the like.
In order to achieve the above object, accomplish above-mentioned task, a kind of lightweight stone paper of the present invention adopts following technical scheme.
