Abstract
The invention discloses a kind of environmentally friendly tent coating materials and preparation method thereof, are related to coating material technical field.It is a kind of environmental protection tent coating material be prepared from the following raw materials: cellulose grafted polymer, starch, graphite powder, curing agent, reinforcing fiber, alumina particle, coupling agent, polyphenylene oxide micro mist, the present invention carries out graft polymerization in situ under the action of redox initiator, catalyst to cellulose derivative, the compatibility of cellulose grafted polymer and inorganic material is enhanced, while it being made to be easy to be decomposed by Institute of Micro-biology.The spacing that graphitic molecules are expanded using dry ice enables graphitic molecules to assemble the microorganism in soil using the modification of CTAB, n-amyl alcohol, and improves the reactivity of microorganism.
Description
Technical field:
The present invention relates to coating material technical fields, and in particular to a kind of environmental protection tent coating material and preparation method thereof.
Background technique:
Open air goes camping, and tent is to must be provided with, and tent must specifically have sunshade, ventilation, radix saposhnikoviae, rain-proof, warming etc. more
Weight open air function, outdoor tent must adapt to various weather environments, therefore have higher requirement to the tent that enterprise produces,
Existing tent needs add a variety of coatings in the base fabric of tent to enhance the function of tent itself, make the tent produced more
Add with practicability, there can be effective sunshade, ventilation, radix saposhnikoviae, rain-proof, warming.The common material of coating at present
There are PVA, PU etc., but the function of this kind of material is relatively simple, physical property is poor, is easy to happen for a long time using rear coating de-
The problems such as falling, deforming, and coating material generally can not natural degradation, be easy cause damages to natural environment.
Summary of the invention:
Technical problem to be solved by the present invention lies in provide the tent coating of a kind of excellent physical properties, environment-friendly degradable
Material and preparation method thereof.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of environmental protection tent coating material, is made of the raw material of following parts by weight:
40-50 parts of cellulose grafted polymer, 20-30 parts of starch, 5-10 parts of graphite powder, 5-10 parts of curing agent, enhancing are fine
Tie up 2-5 parts, 2-5 parts of alumina particle, 2-5 parts of coupling agent, 2-5 parts of polyphenylene oxide micro mist.
Tent coating material the preparation method comprises the following steps: accurately weigh formula in raw material, be added automatic blender in mix, mix
The conjunction time is low speed 2min/ high speed 5min；Wherein low speed is 110r/min, is at a high speed 200r/min；Mixed raw material is successively passed through
The melting extrusion of extruder, the tabletting of tablet press machine be broken, the sieve powder of the Crushing of Ultrafine of pulverizer and rotary screen, hybrid packed at production
Product.
The preparation method of the cellulose grafted polymer, comprising the following steps:
(1) water soluble vitamin derivative is add to deionized water, 40 DEG C of stirrings are to being completely dissolved；
(2) under the action of protective gas, redox initiator, 40 DEG C of stirring 10- are added to the solution in step 1
15min adds grafted monomers and is warming up to 85-90 DEG C, stir 1-2h, is cooled to 70-75 DEG C, and catalyst is added and continues to stir 1-
2h；
(3) into step 2, reaction system is added chain terminating agent and terminates reaction, is cooled to room temperature and 10-20min is stirred by ultrasonic
Afterwards, centrifuge washing is distinguished with deionized water and dehydrated alcohol, be then dried in vacuo to get cellulose grafted polymer is arrived.
The quality of the water soluble vitamin derivative, redox initiator, grafted monomers, catalyst, chain terminating agent
Than for 40-50:1-5:100-200:1-5:1-5.
The water soluble vitamin derivative is selected from hydroxymethyl cellulose or hydroxypropyl cellulose.
The protective gas is selected from nitrogen or argon gas.
The redox initiator is potassium peroxydisulfate/sodium thiosulfate.
The grafted monomers are that acrylamide and maleic acid and mixture, mass ratio 1:0.6-0.8 are repeatedly tried
Verifying, the mix monomer is higher than the grafting efficiency of single monomer, and under the mass ratio mix monomer efficiency highest.
The chain terminating agent is hydroquinone.
The catalyst is N,N-dimethylformamide.
The power of the ultrasonic agitation is 300-500W, mixing speed 300-400r/min.
The method of modifying of the graphite powder are as follows: dry ice is added into graphite powder, is stirred, is then placed in the mixture
In liquid nitrogen system, the mixture of graphite powder and dry ice is stirred into 30-40min, is then allowed to stand 5-10min, stirs 30-40min,
Then 30-60min is stood in the environment of the mixture of graphite powder and dry ice being placed in 20-40 DEG C, leaves graphite to dry ice sublimation
Powder；The ethanol solution that concentration is 90% is added into graphite powder again, is heated to reflux state insulated and stirred 0.5-1h, be added sun from
Sub- Surfactant CTAB, cosurfactant n-amyl alcohol continue insulated and stirred 1-2h, filter while hot, and filter cake is sent into drying box
In, 80-90 DEG C of drying 2-3h；It is finally sent into nano-milled instrument and pulverizes to get modified graphite powder is arrived.
The graphite powder, dry ice, 90% ethanol solution, CTAB, n-amyl alcohol mass ratio be 10-15:10-15:20-40:
1-5:1-5.
The curing agent is selected from one of m-phenylene diamine (MPD), diaminodiphenyl-methane, diamino-diphenyl alum.
The reinforcing fiber is selected from carbon fiber or glass fibre, and reinforcing fiber can significantly increase the intensity of coating entirety and tough
Property, fiber filament diameter is 10-50 μm, and for length at 15-18 μm, for coating under the operating condition that resistance to bulky grain impacts, effect is outstanding
It is significant.
The partial size of the alumina particle is 10-50nm, and the alumina particle under the partial size can enhance the flexibility of coating
And fold resistance, improve the service life of coating.
The coupling agent is titanate coupling agent.
