In such scheme, described high molecular polymer is that one or more in polyvinyl alcohol, peach gum, guttapercha, gum rosin mix in any proportion.
In such scheme, described increase-volume softening agent is that one or more in maleic anhydride, ethylene glycol, citrate, glycerine, polyoxyethylene glycol, polypropylene glycol, vanay, stearic acid, single stearic acid glycerine lipoprotein mix in any proportion.
In such scheme, described functional aid is deodorant, one or more in insect-proof agent, sanitas, surface filming auxiliary agent, viscosity reduction auxiliary agent mix in any proportion.
In such scheme, described deodorant is that the one or both in cyclodextrin, L-AA mixes in any proportion.
In such scheme, described insect-proof agent is shiu oil, desinsection chrysanthemum, one or more in chitin mix in any proportion.
In such scheme, described sanitas is that one or more in Charantin, chitin, pectin mix in any proportion.In such scheme, described surface filming auxiliary agent is polyvinyl alcohol, one or more in polyvinyl pyrrolidone, polyvinyl pyrrolidone/acetate ethylene copolymer, polyvinyl butyral acetal mix in any proportion.
In such scheme, described viscosity reduction auxiliary agent is that one or more in light calcium carbonate, paraffin, titanium dioxide, wilkinite, sodium bentonite mix in any proportion.
The preparation method of above-mentioned a kind of biomass-based spongy foam filler, comprises the following steps:
1) raw material is chosen
Undertaken taking for subsequent use by weight percentage shared by each raw material: Vegetable oil lipoprotein 10-20%, vegetable fibre 5-10%, plant powder 50-70%, high molecular polymer 5-20%, increase-volume softening agent 5-15%, whipping agent 4-15%, functional aid 1-5%;
2) raw materials pretreatment
Vegetable fibre is placed in fiber fine powder machine, powder particle diameter to 800 order sieving for standby;
3) the increase-volume plasticising of Vegetable oil lipoprotein, vegetable fibre:
Pretreated vegetable fibre, increase-volume softening agent, Vegetable oil lipoprotein are placed in successively and are with the cantilever double-spiral conical mixer of interlayer of heating to carry out blended; Blending reaction temperature is 80-95 DEG C, and the time is 35-40 minute, obtains oily gum pasty state mixture, for subsequent use;
4) the common appearance of preparing Vegetable oil lipoprotein, vegetable fibre, plant powder and high molecular polymer expects
Plant powder, high molecular polymer are placed in the temperature control reaction mixing machine with high, medium and low third gear, open mixing machine and be adjusted to low speed gear, slowly step 3 is added in this speed stage) gained oily gum pasty state mixture, mixing temperature controls at 70-80 DEG C, and mixing time is 5-8 minute; After treating that oily gum pasty state mixture adds, regulate mixing machine rotating speed to be high gear, and control material temperature and rise to 90-120 DEG C, this stage mixing time is 8-10 minute; Now regulate mixing machine rotating speed to be mid ranger, mixing temperature controls at 95-100 DEG C, and this stage mixing time is 5-10 minute; Finally by mixing machine speed setting to low speed gear, mixing temperature is down to less than 70 DEG C, progressively adds functional aid, and this stage mixing time is 5-15 minute, and the sand shape obtaining surperficial slightly oiliness holds material altogether, for subsequent use;
The above-mentioned temperature control reaction mixing machine with high, medium and low third gear, the speed of its high gear is 2400 revs/min, and the speed of mid ranger is 900 revs/min, and the speed of low speed gear is 120 revs/min;
5) add whipping agent, make masterbatch
