Description
[technical field]
The present invention relates to a kind of polyurethane foam composite and production method thereof of supporting by the arm the bamboo charcoal powder.
[background technology]
Polyurethane foamed material has been widely used in people's the daily life, as the sandwich material in compartment, seat, doss, protection pad etc., is to utilize its porous, whippy characteristic to give soft comfort and for it mostly.Though be difficult for distributing moisture but the regular foam material can absorb moisture, receive dirty smelly easy breeding germ, CN1865326 discloses " a kind of bamboo charcoal sponge and preparation method thereof " for this reason, CN1478817 discloses " anti-microbial elastomeric polyurethane nano composite material and preparation method thereof ", is useful to hygroscopic desiccation, the antibacterial deodourizing performance that increases and improve foam material.But the bamboo charcoal in the CN1865326 patent application includes 15%-50% in sponge, ratio is higher, influences the maintenance of sponge primary characteristic, and bamboo charcoal is not done particular process and selection, can not fully excavate the relevant good characteristic of bamboo charcoal.Contain heavy metal ion and organic antibacterial agent in the matrix material of CN1478817 patent application, cause the pollution of environment and the germinating of anti-medicine bacterium to a certain extent.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of iodine sorption value and reaches 500-700mg/g, particle diameter 1000-3000 purpose bamboo charcoal powder, and a kind of poly-ammonia foamed composite and production method thereof that contains aforementioned bamboo charcoal powder is provided.
The technical scheme that solves the present technique problem is: this bamboo charcoal polyurethane foam composite material includes following raw materials according and weight part is formed: 30-70 part polyether glycol, 30-70 part tolylene diisocyanate, 5-10 part iodine sorption value are 500-700mg/g and particle diameter 1000-3000 purpose bamboo charcoal powder, 0.5-7 part acrylic copolymer, 1-3 part silicone oil, 0.5-1 part liquefied ammonia, 6-15 part methylene dichloride, 0.5-1 part stannous octoate, 5-10 part water, the formaldehyde adsorptive value of this matrix material is greater than 5mg/g, and the negative ion burst size is 50-400/cm
3, far infrared transmissivity is 60%-90%.
Said polyether glycol is polyether Glycols and/or polyether-tribasic alcohol.
The production method of this bamboo charcoal polyurethane foam composite material comprises the steps:
(1) production of bamboo charcoal powder: bamboo split be broken into length less than the fragment of 30cm or use bamboo processing fent except that sawdust, place the charring furnace charing, the high-temperature zone temperature is controlled at 700-1100 ℃, charing 4-8 hour, cool off, unload charcoal, bamboo charcoal pulverizing just is placed on is ground into particle diameter 1000-3000 purpose bamboo charcoal powder in the Raymond mill;
(2) preparation of compound bamboo charcoal powder: bamboo charcoal powder that step (1) is made and acrylic copolymer dispersion agent are that 1: 0.1～0.7 ratio mixing is standby by weight;
(3) preparation of prepolymer: mixing is mixed thoroughly stand-by in the reactor under 26 ℃ of-30 ℃ of envrionment conditionss by each raw material of described all the other except that tolylene diisocyanate of claim 1 and weight part thereof;
(4) making of foamed composite: the prepolymer that step (3) is mixed with keeps 26 ℃ of-30 ℃ of temperature, add 30-70 parts by weight of toluene vulcabond fast, stir 3-6 second with 1200 rev/mins rotating speeds, banish foaming to the moulding box immediately, the demoulding, cooling.
It is shell and tube moving-bed dry distillation carbonizing furnace that the said bamboo charcoal of making bamboo charcoal powder is produced used charring furnace.
The invention has the beneficial effects as follows bamboo charcoal polyurethane foam composite material except that have moisture absorption inhale smelly, soft high resilience, make the people comfortable, also because of containing high absorption property and the greatly existence of the bamboo charcoal powder of specific surface area, the adsorptive value of free formaldehyde is greater than 5mg/g, negative ion burst size 50-400/cm
3Far infrared transmissivity 60%-90%, this matrix material is as the memory sponge when being used to make sofa, mattress, compartment sandwich material, and is in the good environment that pollution, the air that the people is placed oneself in the midst of be not subjected to or be subjected to Toxics such as free formaldehyde less be clean relatively, stimulate circulation, healthy.
[embodiment]
Further specify the present invention with several representational embodiment below the present invention: in the raw material of application and the weight part proportioning thereof, what amount was maximum is polyether glycol and tolylene diisocyanate, respectively account for 30-70 weight part (down together), this is to decide according to the density requirements of made foamed composite, require the high increasing polyether glycol share of density, reduce the share of tolylene diisocyanate and other frothing aid, require low density, then opposite.
(annotate: binary, ternary are respectively the abbreviation of polyether Glycols and polyether-tribasic alcohol in the table)
The production stage of this foamed composite is: the production of (1) bamboo charcoal powder: bamboo is split be broken into length less than the fragment of 30cm or use bamboo processing fent except that sawdust, place the charring furnace charing, the high-temperature zone temperature is controlled at 700-1100 ℃, charing 4-8 hour, cool off, unload charcoal, bamboo charcoal pulverizing just is placed on is ground into particle diameter 1000-3000 purpose bamboo charcoal powder in the Raymond mill; (2) preparation of compound bamboo charcoal powder: bamboo charcoal powder that step (1) is made and acrylic copolymer dispersion agent are that 1: 0.1～0.7 ratio mixing is standby by weight; (3) preparation of prepolymer: mixing is mixed thoroughly stand-by in the reactor under 26 ℃ of-30 ℃ of envrionment conditionss by each raw material of described all the other except that tolylene diisocyanate of claim 1 and weight part thereof; (4) making of foamed composite: the prepolymer that step (3) is mixed with keeps 26 ℃ of-30 ℃ of temperature, add 30-70 parts by weight of toluene vulcabond fast, stir 3-6 second with 1200 rev/mins rotating speeds, banish foaming to the moulding box immediately, the demoulding, cooling.
