Abstract
A filler of a plywood adhesive is composed of the following raw materials by weight: 50-70% of manioc waste dry powder and 30-50% of modified blend substance. The modified blend substance comprises the following components by weight: 60-80% of organic bentonite and 20-40% of sodium silicate. The filler of the plywood adhesive can completely replace flour serving as grain, saves a large amount of grains, and resolves the environment problems produced in the process for producing alcohol by directly utilizing manioc waste residue and manioc starch in a large scale. Cost of the manioc waste residue and the manioc starch is far lower than price of flour.
Description
Technical field
The present invention relates to a kind of weighting agent of glued board adhesive, the weighting agent of the glued board adhesive particularly utilizing tapioca (flour) or utilize cassava to produce the waste residue produced in alcohol process to prepare.
Technical background
Tapioca (flour) or utilize cassava to produce in alcohol process, can produce a large amount of waste residue.After testing, dry manioc waste, not only containing a large amount of xylogen, Mierocrystalline cellulose, also contains the starch of more than 30%.Whenever squeezing season, namely produce season, a large amount of waste residue fills up the slag pool, and slowly wait for that peasant household takes away and make fertilizer or feed pigs, do food fillers when pig valency is low, digestibility is very low, and the odor pollution surrounding enviroment of generation, masses' suggestion is very large.Also there is no at present a kind of mass-producing, comprehensive utilization way that economy is stronger.
Plywood production sticks with glue agent and is generally resol and urea-formaldehyde resin, for increase resin initial viscosity, improve Bear-grudge plate pre-compressed effect, improve bonding quality, reduce tackiness agent cost, all to add a certain proportion of weighting agent in resin, flour is the good weighting agent generally adopted, and its add-on is generally 10% ~ 40% of tackiness agent (weight).
According to ASSOCIATE STATISTICS, 2011, the annual glued board output of China was 1.18 hundred million m
3, according to about 70kg/m
3tackiness agent consumption is calculated, if there is 80% manufacturing enterprise face powder as filler, then the annual flour consumed is more than 1,300,000 tons.Calculate by 2500 yuan/t, economic worth, more than 32.5 hundred million yuan, consumes a large amount of flour, causes grain nervous.
Summary of the invention
The object of the invention is to the weighting agent of the glued board adhesive utilizing tapioca (flour) or utilize cassava to produce the waste residue produced in alcohol process to prepare; the flour as grain can be substituted completely; not only save a large amount of grain; also solve mass-producing and directly utilize waste cassava residues; solve the environmental problem utilizing cassava to produce starch and the generation of alcohol process, and cost is significantly less than flour price.
The present invention achieves the above object by the following technical solutions: a kind of weighting agent of glued board adhesive, is mixed by the raw material of following weight part:
Manioc waste dry powder 50-70%
Improvement blend 30-50%.
Described improvement blend consisting of by weight:
Inorganic bentonite 60-80%
Water glass 20-40%.
The application of weighting agent in plywood production of described glued board adhesive is 64 ~ 88:12 ~ 36 by weight to be fully uniformly mixed resol or urea-formaldehyde resin adhesive and described weighting agent, then gives the gluing of glued board blanket.
Described manioc waste dry powder is tapioca (flour) or utilizes cassava to produce the waste residue produced in alcohol process, through the dry slag that mechanism filter-pressing dehydration, drying or natural drying to water ratio are less than 15%, then reaches 120 order-160 orders through mechanical disintegration to fineness.
Method, the step of the addition means of described weighting agent in plywood production, operation steps and interpolation flour are the same.
The effect that the present invention gives prominence to is: adopt tackiness agent weighting agent of the present invention; the flour as grain can be substituted completely; not only save a large amount of grain; also solving mass-producing directly utilizes waste cassava residues and tapioca (flour) to produce the environmental problem of alcohol process generation, and cost is significantly less than flour price.
Embodiment
By the following examples technical scheme of the present invention is described further.
Embodiment 1
The weighting agent of glued board adhesive of the present invention, concrete preparation method is as follows:
Take from the manioc waste that drips on the tapioca (flour) factory sediment pool, go most of moisture by squeezing machine pressure, natural drying is less than 15% to water ratio, through pulverizing unit processing, fineness reaches 120 orders, is mixed by this cassava ground-slag, then carry out weather-proof dressing by weight for 60:40 with improvement blend.Described improvement blend is in inorganic bentonite: water glass ratio is 75:25.
By weight for 75:25, resol or urea-formaldehyde resin adhesive and described weighting agent are fully uniformly mixed, then give the gluing of glued board blanket.
Embodiment 2
For decorative sheet
Take from the manioc waste that drips on the tapioca (flour) factory sediment pool, go most of moisture by squeezing machine pressure, natural drying is less than 15% to water ratio, through pulverizing unit processing, fineness reaches 120 orders, is mixed by this cassava ground-slag, then carry out weather-proof dressing by weight for 60:40 with improvement blend.Described improvement blend is in inorganic bentonite: water glass ratio is 70:30.
By weight for 64:36, resol or urea-formaldehyde resin adhesive and described weighting agent are fully uniformly mixed, then give blanket gluing.
Embodiment 3
For building template
Take from the manioc waste that drips on the tapioca (flour) factory sediment pool, go most of moisture by squeezing machine pressure, natural drying is less than 15% to water ratio, through pulverizing unit processing, fineness reaches 120 orders, is mixed by this cassava ground-slag, then carry out weather-proof dressing by weight for 60:40 with improvement blend.Described improvement blend is in inorganic bentonite: water glass ratio is 75:25.
By weight for 88:12, resol or urea-formaldehyde resin adhesive and described weighting agent are fully uniformly mixed, then give blanket gluing.
