The present invention provides a kind of sound absorption curtain fabric, the fabric uses yarn with sound absorption function and glass fibre is blended forms：The yarn with sound absorption function is to be soaked into before spinning in the liquid with sound absorption function；The liquid with sound absorption function is prepared by following component with parts by weight：Pineapple peel cellulose crystallite/7-10 parts of polyaniline composite aerogel microballoon, 1-2 parts of floating bead, 2-3 parts of four acicular type zinc oxide crystal whisker, 2-5 parts of thickener, 10-20 parts of aqueous polyurethane, 5-10 parts of pentaerythrite, 2-5 parts of polyethylene glycol 400,2-4 parts of soybean protein of glucose grafting, 100-150 parts of distilled water.The sound absorption curtain fabric of the present invention all has good assimilation effect in medium-high frequency acoustical range, belongs to efficient sound-absorbing material.
Description
Technical field
The present invention relates to textile material fields, and in particular to a kind of sound absorption curtain fabric.
Background technology
In fields such as industrial manufacture, household electrical appliance, the vehicles and urban architectures, noise and vibration control is by more next
More concerns.As the noise pollution arranged side by side with atmosphere pollution, water pollution and noxious waste pollution, it has also become today's society
One of four overall situation public hazards, public normal of severe jamming learn, live and work.Noise is easy to make one to feel tinnitus, the heart
Unbearably, irritated, seriously affect the health and quality of life of people.As people's health consciousness enhances, sound-absorbing material is answered
With also more and more extensive.In common residential environment, general door and window etc. is all used as sound-absorbing material using glass, but glass door
Window simultaneously must be fastened closed, can not ventilate, also be unfavorable for the health of people.And curtain, another as door and window must
Accessory is needed, if it can be made to have sound absorbing performance, can effectively solve the problems, such as air circulation, while solving noise problem.
Invention content
Technical problems to be solved：In domestic environment generally sound absorption noise isolating is carried out using glass door and window, but glass door
Air can not circulate after window closing, influence health, the object of the present invention is to provide a kind of sound absorption curtain fabrics, in medium-high frequency
All there is good assimilation effect in acoustical range, belong to efficient sound-absorbing material, can effectively be solved while absorbing sound noise isolating
The problem of air circulation.
Technical solution：A kind of sound absorption curtain fabric, the fabric use the yarn with sound absorption function and glass fibre mixed
It spins：The yarn with sound absorption function is to be soaked into before spinning in the liquid with sound absorption function；It is described that there is suction
The liquid of sound function is prepared by following component with parts by weight：Pineapple peel cellulose crystallite/polyaniline composite aerogel microballoon
7-10 parts, 1-2 parts of floating bead, 2-3 parts of four acicular type zinc oxide crystal whisker, 2-5 parts of thickener, 10-20 parts of aqueous polyurethane, pentaerythrite
5-10 parts, 2-5 parts of polyethylene glycol 400, glucose grafting 2-4 parts of soybean protein, 100-150 parts of distilled water.
Further, the mass ratio of the yarn and glass fibre with sound absorption function is 30:1.
Further, the yarn is cotton fiber or polyester fiber.
Further, the thickener is methylcellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl
One or more of cellulose, polyvinyl alcohol, polyvinylpyrrolidone, polyethylene glycol oxide, polyacrylic acid or Sodium Polyacrylate.
Further, the grain size of the floating bead is≤100 μm.
Further, four acicular type zinc oxide crystal whisker length≤100 μm.
Further, the preparation method of the pineapple peel cellulose crystallite/polyaniline composite aerogel microballoon is：
The first step：70g polyanilines and 1000mL petroleum ethers is taken to mix, ultrasonic wave disperses 3h, obtains dispersing polyaniline liquid；
Second step：It takes 1.25g pineapple peels cellulose crystallite and 25mL ionic liquid chlorination allyl -3- methylimidazoles to mix, adds
Heat adds 4mL acetic anhydride and continues to stir 3h to 80 DEG C of stirring 3h；
Third walks：Dispersing polyaniline liquid is added, stirs 30min at 60 DEG C, pours into standing and defoaming on glass plate；
4th step：It immerses after 5-6h in ethyl alcohol carries out solidification regeneration and with ethyl alcohol wash 3-5 times, then must be answered with acetone bubble 5-6h
Close gel；
5th step：Plural gel is sprayed through high-pressure atomization method to form microballoon, then is collected using liquid nitrogen as coagulating bath；
6th step：It puts microballoon into freeze drier and 1-3h is dried to obtain the final product.
Further, the preparation method of the glucose grafting soybean protein is：
Step（1）：By soybean protein isolate and glucose with mass ratio for 1:1 amount is dissolved in distilled water, uses magnetic agitation
Machine stirs
Mix 30-40 min；
Step（2）：It is placed in 6 h of pre-freeze at -60 DEG C, is put into freeze drier and is dried in vacuo to obtain freeze-dried powder；
Step（3）：The aluminium box for filling freeze-dried powder is placed in bottom to fill in the drier of saturation KBr solution, is put into drying box,
55 DEG C of temperature is reacted under relative humidity 79% to obtain the final product.
Further, the preparation method of the liquid with sound absorption function：
The first step：Aqueous polyurethane, thickener, glucose grafting soybean protein and distilled water are mixed, magnetic agitation 20-
30min；
Second step：Pentaerythrite is added and polyethylene glycol 400 continues to stir 5-10min；
Third walks：Remaining ingredient is added, continues magnetic agitation 1-2h to obtain the final product.
Further, the preparation method of the pineapple peel cellulose crystallite is：
The first step：Pineapple peel distilled water is cleaned and is placed on dry 24-48h in 80 DEG C of baking oven, shreds into 1mm × 4mm
Pane, be placed in volume ratio be 2:It boils, removes, the wax on surface in 1 toluene ethanol solution, filtering, ethyl alcohol is washed
It washs, it is dry；
Second step：The processed pineapple peels of 8g are placed in the mixed solution of the 50 % ethyl alcohol containing 0.1mol NaOH and 200 mL
In, 3h is stirred at 45 DEG C, washing is dry after filtering；
Third walks：150 mL are added and contain 10 % NaOH and 1% Na2B4O7·10H2The solution of O is stirred at 28 DEG C
15h is handled, washing is dry after filtering；
4th step：It is 10 that 150mL, which is added, to contain volume ratio:The solution of 1 80% acetic acid and the mixing of 68 % nitric acid, at 120 DEG C
15-30min is managed, 95 % ethyl alcohol is taken out and distillation water washing, filtering is drying to obtain.
Advantageous effect：
1. polyester fiber is most common fiber, cheap, it is simple to manufacture, generally all based on weaving, therefore seldom as suction
