Description
Technical field
The present invention relates to foam sponge technical field, particularly relate to the matrine foam-rubber cushion of a kind of biological antibiotic virus killing.
Background technology
Polyurethane low resilience urethane foam resilient foam, due to the comfort property of its excellence, has been widely used in household articles, automobile, footwear
The field such as material, medical apparatus and instruments, polyurethane rebound foam, due to the molecular structure of its uniqueness, has higher comfort property, when being subject to
During to certain pressure, polyurethane rebound foam can change shape along with pressure, makes pressure be evenly distributed, and reduces local pressure
Point, after pressure is released, its shape the most slowly returns to original state.But due to the hole-closing structure of himself, polyurethane slow rebound steeps
The permeability of foam and damping sound absorbing capabilities are poor." synthesis of soybean oil polyol and grinding of polyurethane low resilience urethane foam resilient foam performance
Studying carefully " author has been synthesized modified soybean oil by maleic anhydride and soybean oil, then with diethylene glycol and modified soybean in a literary composition
Oil reacts under the catalysis of potassium hydroxide, has synthesized soybean oil polyol.The soybean oil polyol of recycling synthesis is prepared for greatly
Oleum Glycines polyol based polyurethane low resilience urethane foam resilient foam, in article, the stretching to soybean oil polyol based polyurethanes low resilience urethane foam resilient foam is strong
The mechanical properties such as degree, elongation at break and 40% degree of compression are studied, and find that the use of soybean oil polyol can improve polyurethane
The permeability damping capacity of low resilience urethane foam resilient foam and sound absorbing capabilities, but the decline of mechanical property can be caused, propose to increase foaming
Agent water consumption or raising isocyanate index, can have higher ventilative at soybean oil polyol based polyurethanes low resilience urethane foam resilient foam
On the premise of performance, damping capacity and sound absorbing capabilities, improve its mechanical property.
Although author is by soybean oil modified thus synthesize soybean oil polyol based polyurethanes rebound foam, improve slow
The permeability of recovery sponge, damping capacity and sound absorbing capabilities, but the bad shortcoming of its bad mechanical strength, toughness reduces material
The service life of material and the comfort level of people, affect the quality of product, does not promotes expanding economy, and its slow time prepared
Playing sponge and can't fully meet the nowadays people's various demands to foam-rubber cushion, so needing further to improve, improving it
Other performances such as mechanical property, heat stability, hydrophobicity, expand application and increase the service life.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the matrine sponge of a kind of biological antibiotic virus killing
Pad.
The present invention is achieved by the following technical solutions:
The matrine foam-rubber cushion of a kind of biological antibiotic virus killing, is made up of the raw material of following weight portion: microcrystalline Cellulose 35-
45, soybean oil 140-180, diethylene glycol 160-200, potassium hydroxide 0.13-0.27, polyether polyol 90-110, foaming agent 8-12,

Both are thoroughly mixed uniformly by 160-180 DEG C, then are placed in heating mantle by four-hole boiling flask, add diethylene glycol and hydroxide
Potassium, rises high-temperature and reacts 3-4h to 200-220 DEG C, and washing purifies, separatory removes unreacted impurity, standby after drying;
(3) matrine, magnetic microsphere, gelatin are dissolved in deionized water according to mass ratio 1:6-6.5:2 mixing, water at 60 DEG C
Bath heating for dissolving, prepared concentration is the gelatin magnetic solution of 15%, then liquid paraffin, sorbester p17 is mixed according to volume ratio 100:1
Preparation mixing oil phase, stirs gelatin magnetic solution at bath temperature 60 DEG C, and stir speed (S.S.) is 800r/min, more gradually drips
Reacting 1-1.5h after stirring 10min in oil phase in ice bath, reaction drips appropriate formaldehyde and continues stirring reaction 1-2h after terminating,
Reaction uses absolute ethanol washing after terminating, standby after vacuum drying;
(4) product, polyether polyol and other surplus materialss mixing in addition to toluene di-isocyanate(TDI) prepared by step (2),
At room temperature stir with the rotating speed of 3000 revs/min, be stirring evenly and then adding into product prepared by step (3), be subsequently adding first
Pour into rapidly in foam box after phenylene diisocyanate stirring 4-6S, remove from casing after 15-20min and get final product.
The matrine foam-rubber cushion of described a kind of biological antibiotic virus killing, described polyether polyol is many by polyether polyol 1, polyethers
Unit alcohol 2, polyether polyol 3 precentagewise content 10%-30%, 10%-20%, 20%-50% respectively mix, polyether polyol 1

Alcohol, polyether polyol 3 is the hydroxyl value trifunctional polyether polyol at 250-280.
The invention have the advantage that vegetable oil based polyalcohol is a kind of potential Biodegradable material, with the high score of synthesis
Sub-material is compared, and can effectively alleviate problem of environmental pollution, the present invention at the discarded rear degradable or Partial digestion of goods
Utilize cellulose concentration advantage little, degradable modified high-molecular synthetic material, but the mechanical property of cellulosic material is the highest,
Poor mechanical property and the most high thermally-stabilised application that governs, the present invention uses octadecylisocyanate graft modification crystallite
Cellulose improves its hot strength, heat stability and wearability, then with it to soybean oil modified, obtains the soybean oil of excellent performance
Polyhydric alcohol, environmental protection, then by soybean oil polyol and unclassified stores synthesis of polyurethane foam sponge, there is dredging of excellence
Water, damp, the performance such as breathe freely, also improve intensity and the mechanical property of sponge, matrine has excellent parasite killing, antibiotic property
Can, the present invention utilizes gelatin, matrine etc. to prepare matrine magnetic micro-ball to add in polyurethane foam sponge, the most not shadow
Ring the foam performance of polyurethane itself, and can be formed to cross-link in foaming process matrine is well dispersed in sponge
In, reach environmentally safe after antibacterial, parasite killing, effect of virus killing, and discarded use, can freely decompose, prepared by the present invention
Matrine foam-rubber cushion preparation technology simple, material source is wide, is uniformly dispersed in sponge, and can reach good anti-
Bacterium, virus killing, the effect of parasite killing, environmental protection, it is worthy to be popularized.
