Abstract
The invention provides a special adhesive for stone paper and a preparation method thereof. The adhesive is characterized by containing fine fibers, and is composed of the following components in parts by weight: 40-55 parts of edible seaweed glue powder, 15-20 parts of alkyd resin, 10-25 parts of reinforcing fiber, 0.5-1 part of organic silicon, 0.5-1 part of dispersing agent and a right amount of water. The stone paper is connected through the fine fibers to implement quick bonding by utilizing the permeation of the alkyd resin and the tackifying of the edible seaweed glue powder; and especially, the adhesive can be dispersed in hot water, thereby implementing bonding processing of the stone paper on the traditional paper product processing equipment.
Description
Technical field
The present invention relates to adhesive material field, be specifically related to a kind of stone paper adhesive specially, and relate to the preparation method of this kind of tackiness agent further.
Background technology
Paper industry is considered to the industry of a contaminate environment, welding in the world, is also the rich and influential family of timber and energy consumption.China is a forest reserves country that there is a serious shortage in the supply, is all difficult to the fact breaking away from most of paper pulp fiber dependence on import for a long time.Need to adopt the operations such as boiling, bleaching, washing, drying in the production process of paper industry paper pulp, a large amount of waste gas and waste water can be discharged, cause the severe exacerbation of blowdown river basin ecological environment.And stone paper is with inorganic stone flour for main raw material, add a small amount of synthetic resins and auxiliary agent, the environment-friendly type sheet paper products obtained by different thermal forming devices, vegetable fibre that in process of production need not be traditional, does not have the discharge of waste water and waste gas.Therefore, the paper substituting natural plant fibre manufacture with environmentally-friendly stone paper is the trend and direction that current paper industry develops, and is conducive to reducing the felling to trees, the ecotope of the protection mankind.
Stone paper has huge market potential and excellent performance, but due to be added with in the preparation process of stone paper a small amount of thermoplastic macromolecule material as: polyethylene (PE), polypropylene (PP) etc., thus cause the characteristic of stone paper and traditional fibre paper there are differences.Especially stone paper is used for paper product and adds man-hour, rely on traditional tackiness agent to be difficult to stone paper bonding, when thus causing stone paper to be processed into the goods such as paper bag, carton, fluting board, cementability is affected.Thus cause stone paper cannot adapt to existing paper product processing units.
Bonding in order to realize stone paper, Chinese invention patent CN102873866A discloses a kind of method utilizing the bonding stone paper of high-frequency induction welding technique, multiple stone paper are stacked mutually or multiple interfaces of stone paper are stacked mutually, put into high-frequency induction welding machine again, weld 0.5-2 second, take out.This invention make use of the hot melt characteristic of stone paper, but due to the thermally melting polymer content in stone paper few, major part is inorganic powder, therefore utilizes the bonding force of high-frequency induction welding technique relatively low.Time bonding in particular for the special-shaped paper product such as carton, fluting board, high-frequency induction welding technique is difficult to be applied in existing paper product processing units.
It is bonding that hot melt adhesive can realize stone paper, but can only be used for simply bonding, cannot be used for fluting board compound sticking.And the bonding stone paper of hot melt adhesive can cause the face thermal distortion of stone paper paper thus destroy paper structure.
According to above-mentioned, in order to advance stone paper to replace traditional fibre paper, solution is needed to realize the bonding of stone paper in equipment in existing paper product processing.And technique scheme be difficult to adapt to stone paper on legacy equipment, carry out paper product processing.Therefore, need a kind of glue to be directly used in paper product processing that existing fibrous paper bond processing equipment realizes stone paper, and has good versatility, does not need to transform existing fibrous paper bond processing equipment.
Summary of the invention
For the bonding Problems existing of stone paper, in order to adapt to carry out stone paper bond processing on conventional paper processing equipment for product, the present invention proposes a kind of stone paper adhesive specially, this tackiness agent contains microfibre, the thickening of the infiltration of Synolac and edible seaweed rubber powder is utilized to make stone paper by the connection of microfibre thus quick-binding, especially this tackiness agent can disperse in the hot water, realize stone paper carry out on conventional paper processing equipment for product bonding processing, for paper bag, carton, fluting board bonding.The preparation method of stone paper adhesive specially is provided further.
A kind of stone paper adhesive specially, is achieved by the following technical solution:
A kind of stone paper adhesive specially, it is characterized in that: containing organic-silicon-modified microfibre, each component of composition is counted by weight:
