Abstract
The invention discloses a kind of bamboo material: silica gel chopsticks and chopsticks kernel, the outer layer of the chopsticks kernel is the silica gel mixture layer adhesive to the chopsticks center. The preparing method comprises: getting natural bamboo or wood, processing it to chopsticks kernel shape after dewatering and drying; mixing the silica gel and filling material according to proportion of 80: 30- 20, adding silica gel curing agent according to proportion of 1%- 2% of the total weight, stirring and smelting; coating the silica gel mixture on the mould plate, putting the chopsticks kernel on the center of mould, coating the silica gel mixture on the grid mould and striking-off and consolidating, folding the mould and putting in the pressing machine; the temperature of the mould in the pressing machine rising to 180-220 Deg C, the pressure regulated to 5-15 Mpa, thermo insulating for 3-10 minutes, getting out after cooling. The surface of the bamboo is irregularity with space, which are bonded together by the colloid particle under proper temperature and pressure, and forming a transparent or semitransparent bonding layer, the silica gel chopsticks is characterized by anti-pollutant, damp-proof, fungus-proof, anti-skid, and durable, the shape and color is determined depending on the love of user.
Description
Technical field
The present invention relates to tableware and improve,, the invention still further relates to the forming method that bamboo wood chopsticks material combines with silica gel particularly about the improvement of chopsticks.
Background technology
Since human invention chopsticks, the bamboo and wood material has economical and practical advantage as chopsticks, for numerous crowds use so far.Because bamboo and wood materials non-refractory, make the bamboo wood chopsticks can not carry out high temperature sterilization, be because the bamboo wood chopsticks is mouldy easily on the other hand, allow the people feel unclear unclean, also have the various coating of bamboo wood chopsticks surface coated to increase attractive in appearance and to improve the grade insalubrity thereby be out of favour the same with plastics chopsticks but coating comes off easily.Also have with metal material and make chopsticks, silver chopstick for example, but it costs an arm and a leg, and can only be enjoyed by a few peoples.CN2472601Y proposes the anti-skidding stainless steel chopsticks of a kind of hollow, and it is made an alligatoring top layer and makes high temperature resistant printing ink patterned layer on one's body chopsticks on the chopsticks mouth.Though it has anti-skidding high temperature-resistant disinfected advantage, easily scald one's hand when the stainless steel that conducts heat fast uses, thereby be difficult to promote the use of.Popular now disposable chopsticks cause the felling bamboo in enormous quantities wood woods heavy damage forest reserves like this, make that run off in the territory, climate is unusual.
Summary of the invention
The technical problem to be solved in the present invention is to make traditional bamboo wood chopsticks to have high temperature resistant funginert performance, provides promptly that a kind of to stand micro-wave oven sterilization disinfection with hot water indeformable, not mouldy long-lived bamboo wood chopsticks.
The present invention is directed to above-mentioned purpose the method for making a kind of high temperature resistant funginert again bamboo wood chopsticks is provided.
The present invention realizes above-mentioned target by the following technical solutions.
Silica gel chopsticks, the chopsticks core is bamboo wood or timber, it is characterized in that chopsticks core skin is the silica-gel mixture layer that bonds mutually with the chopsticks core.
The manufacture method of silica gel chopsticks, its feature may further comprise the steps:
A, get natural bamboo or timber, behind dewatered drying, be processed into chopsticks fuse shape;
B, with silica gel and filler in 70～80: 30～20 ratios stir the mixture, and again said mixture are added the silica gel vulcanizing agent in 1%～2% ratio of total amount and stir mixing;
C, above-mentioned mixing silica-gel mixture applied puts down on Die and mould plate, the grid central authorities that the first chopsticks of one-step forming are put the grid mould, again will above-mentioned mixing silica-gel mixture flat spread on to wipe off on the grid mould compressing, matched moulds covers and is placed in the forcing press;
D, forcing press inner mold temperature is risen to 180 ℃～220 ℃, pressure is adjusted in 5Mpa～15Mpa, is incubated 3～10 minutes, and cooling back die sinking is taken out;
E, with the polishing of the silica gel chopsticks of above-mentioned compression moulding, polishing, check.
Described silica gel is edible silica white, or color silica gel or methyl ethylene silica gel.
Described filler is a titanium dioxide, bicarbonate calcium powder or their mixture.
Described silica gel vulcanizing agent also claims twoly two or five, is used for the compression molding of silica gel goods.
Silica gel chopsticks of the present invention are at bamboo wood chopsticks surface bonding one deck silica-gel mixture, produce the silica binder course.Because there are many rough gaps in the fibre structure on bamboo and wood material surface, colloidal particle is extruded attached in these gaps at suitable temperature and pressure, colloid admixture and cellulose are bonded together securely, form layer of transparent or translucent binder course, this binder course has the characteristics of anti-soil, protection against the tide, mildew-resistant, the silica gel chopsticks are nonpoisonous and tasteless, it is the long-lived product of a kind of environmental protection, the product design pattern can design according to consumer taste, silica gel chopsticks of the present invention in addition also has anti-skidding advantage, can clamp cunning food, and not slippage.
