Abstract

The present invention relates to a kind of sludge paper and preparation method thereof.It is mixed using sludge, string, adhesive, lubricant and water, is dehydrated, is molded, being dried, press polish, the technique such as is cut and is made.For sludge paper prepared by the present invention using sludge and string as main raw material(s), the utilization rate of sludge is high, is effectively saved plant (paper) fiber；This material is green, density is low, cost is cheap, directly can discard after use or be reduced into soil, there is good practical value and environmental value.

Description

A kind of sludge paper and preparation method thereof
Technical field
The present invention relates to sludge recycle and biological material preparing technical field, relate generally to sludge the utilization of resources and The preparation of novel environment friendly paper.
Background technology
In recent years, with the enhancing of people's environmental protection consciousness, and energy crisis and resource constraint are recognized gradual Deepen, the research that forest tree resource is substituted with other biomass resources receives more and more attention.
As China's industrialization and urbanization process is progressively accelerated, the water consumption and displacement in city are also stepped up, and are added Acute being skyrocketed through for sludge of sewage treatment plant quantum of output, but the processing Disposal Measures also imperfection for sludge.At present, only Jiangsu Province just there are about 5000 Duo Dun sewage treatment plants daily caused by sludge enter household refuse landfill sites processing.This disposal side Formula, domestic rubbish disposal space is both unreasonably occupied, secondary pollution can be caused again, endanger environment, also waste renewable money Source, the requirement of solid waste process resource is not embodied；More there is partial sludge whereabouts unknown, secondary pollution hidden danger be present. Therefore, appropriate disposing sludge, effectively using sludge resource, improve disposal efficiency and reduce cost of disposal etc. and turn into industry concern heat Point.
Paper-making industry is resources consumption type conventional industries, and under the forest reserves increasingly background of exhaustion, raw material problem has turned into Restrict the key issue of paper industry development.Emerging for a kind of novel papermaking raw material and paper technology will be that paper industry brings technology to remove from office Newly.One kind using sludge as papermaking main material, new sludge cardboard is prepared, for saving paper pulp resource and effectively utilizing sludge Resource has Great significance.
The content of the invention
It is an object of the invention to effectively utilize sludge and waste fiber resource to prepare a kind of environmentally friendly sludge paper, so as to be dirt Mud resource opens up new industrialized utilization method, reduces the use of forest tree resource, solves the problems, such as that integrated timber-paper falls behind relatively.
According to technical scheme provided by the invention, using sludge and string fiber as main raw material(s), water, bonding are added Slurry is made in agent and lubricant uniform stirring, and sludge paper is obtained using sheet forming mechanism.
The sludge is the industrial sludge after municipal sludge, riverway sludge or harmless treatment；
The string is body paper fiber, waste paper fibre, bamboo fibre, stalk fibre etc.；
Described adhesive include cationic rosin size, polyvinyl acetate, polyvinyl alcohol, polyacrylate, starch and its It is more than one or both of modified compound, natural gum.
The lubricant is more than one or both of stearic acid, Tissuemat E, paraffin, ethylene bis stearamide etc..
Preparation technology comprises the following steps：
The first step：String is subjected to broken pretreatment, obtains thinner string；
Second step：The string handled well, sludge, adhesive, lubricant, water are stirred, slurry is made；
3rd step：By mixed slurry by being dehydrated, being molded, drying, press polish, the technique such as cut paper be made.
The product can be abandoned directly after discarded and natural degradation is into plantation soil；Or it is reduced into plantation use through broken Soil is multiplexed or abandoned.
Embodiment
A kind of preparation technology of sludge paper：String 48-90 parts, sludge 9-50 parts, adhesive 0-3 parts, lubricant 0-3 Part, appropriate amount of water.String is body paper fiber, waste paper fibre, bamboo fibre, stalk fibre etc..Sludge is municipal sludge, river course silt Industrial sludge after mud or harmless treatment.Adhesive includes cationic rosin size, polyvinyl acetate, polyvinyl alcohol, poly- third It is more than one or both of olefin(e) acid ester, starch and its modified compound, natural gum.Lubricant be stearic acid, Tissuemat E, It is more than one or both of paraffin, ethylene bis stearamide etc..Preparation technology comprises the following steps：
The first step：String is subjected to broken pretreatment, obtains thinner string；
Second step：The string handled well, sludge, adhesive, lubricant, water are stirred, slurry is made；
3rd step：By mixed slurry by being dehydrated, being molded, drying, press polish, the technique such as cut paper be made.
Product can be abandoned directly after discarded and natural degradation is into plantation soil；Or it is reduced into plantation soil through broken It is multiplexed or is abandoned.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not to this hair It is bright to make any formal limitation, any those of ordinary skill in the art, if putting forward skill not departing from the present invention In the range of art feature, the local equivalent embodiment changed or modified is made using disclosed technology contents, and Without departing from the technical feature content of the present invention, in the range of still falling within the technology of the present invention feature.
