Abstract
The present invention relates to a kind of sludge cardboard and preparation method thereof.It utilizes sludge, and being sufficiently stirred after addition string, water and adhesive, lubricant makes it well mixed.Then mixed slurry be dehydrated, be molded, being dried, press polish, the technique such as cut sludge cardboard is made.Sludge cardboard prepared by the present invention effectively increases the utilization rate of sludge using sludge and string as main raw material(s)；It is green, density is low, cost is cheap, can be reduced into soil after use, have good practical value and environmental value.
Description
Technical field
Recycled the present invention relates to sludge and novel paperboard technical field of material, the circulation for relating generally to sludge are sharp again
With the preparation with new green environment protection cardboard.
Background technology
In recent years, with the enhancing of people's environmental protection consciousness, and energy crisis and resource constraint are recognized gradual
Deepen, turn into industry new trend with novel biomass substitution of resources forest tree resource.Industrialization and urbanization process progressively adds
It hurry up, the water consumption and displacement in city are also stepped up, and are skyrocketed through the quantum of output of sludge of sewage treatment plant, but at this stage
Processing Disposal Measures also imperfection for sludge.As the spin-off of sewage, China produces 30,000,000 tons~40,000,000 every year
Ton municipal sludge (moisture content is 80%).China has put into effect a series of policies and has promoted sludge treatment industry development in recent years.Wherein,
Appropriate disposing sludge, effectively turn into the industry focus of attention using sludge resource and reduction cost of disposal etc..
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 paper fiber resource to prepare a kind of environmentally friendly sludge cardboard, so as to be dirt
Using new industrialized utilization method, and the largely use of reduction paper pulp resource is opened up, it is relative effectively to solve integrated timber-paper for mud
The problem of falling behind.
According to technical scheme provided by the invention, using sludge and string as main raw material(s), add water and adhesive,
Slurry is made in lubricant uniform stirring, by being dehydrated, being molded, drying, press polish, the technique such as cuts cardboard is made.
The string is body paper fiber, waste paper fibre, bamboo fibre, stalk fibre etc.；
The sludge is the industrial sludge after municipal sludge, riverway sludge or harmless treatment；
Described adhesive include alkyl ketene dimer (AKD), cationic rosin size, styrene-acrylate emulsion,
Venamul, polyvinyl alcohol, styrene-butadiene emulsion, polyacrylate dispersion, starch and its modified compound, natural gum
One or both of more than.
The lubricant is stearic acid (HSt), Tissuemat E (PE-Wax), paraffin (Wax), ethylene bis stearamide
One or both of etc. (EBS) more than.
Preparation technology comprises the following steps：
The first step：String is subjected to broken pretreatment, and is beaten, beating degree control is advisable in 25-32 ° of SR；
Second step：The string pre-processed, 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 cardboard be made.
In a kind of above-mentioned sludge cardboard, its calliper produced is 1-8mm.
In a kind of above-mentioned sludge cardboard, its described deflection scope is 3-20mNm.
The product maintains property indices more than -365 days 270 days in natural environment, will then start nature drop
Solution.Obsolete material can be abandoned directly and natural degradation is into plantation soil；Or it is reduced into plantation through broken and is multiplexed with soil
Or abandon.
Embodiment
A kind of preparation technology of sludge cardboard：String 48-90 parts, sludge 9-50 parts, adhesive 0-3 parts, lubricant
0-3 parts, appropriate amount of water.String is body paper fiber, waste paper fibre, bamboo fibre, stalk fibre etc..Sludge is municipal sludge, river
Industrial sludge after road mud or harmless treatment.Adhesive includes alkyl ketene dimer (AKD), cationic rosin size, benzene
Ethylene-acrylate emulsion, venamul, polyvinyl alcohol, styrene-butadiene emulsion, polyacrylate dispersion, starch and its
It is more than one or both of modified compound, natural gum.Lubricant is stearic acid (HSt), Tissuemat E (PE-Wax), stone
It is more than one or both of wax (Wax), ethylene bis stearamide (EBS) etc..Preparation technology comprises the following steps：
The first step：String is subjected to broken pretreatment, and is beaten, beating degree control is advisable in 25-32 ° of SR；
Second step：The string pre-processed, 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 cardboard be made.
The cardboard of production has certain thickness, thickness range 1-8mm.Paperboard stiffness scope is 3-20mNm, described
The paste carton of preparation can be used for the packaging of the small sized products of non-food stuff class such as plastic product, glass product.Product is in natural ring
Property indices are maintained in border more than -365 days 270 days, will then start natural degradation.Obsolete material can be abandoned directly simultaneously certainly
So it is degraded into plantation soil；Or it is reduced into plantation through broken and is multiplexed or is abandoned with soil.
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.
