Description
Technical field
The present invention relates to solid gum processing technology field, in particular to a kind of vulcanizate and sulphur is prepared using the vulcanizate
Change the method for product.
Background technique
Latex is widely used in various techniques and industrial production, especially in American-European holiday gift such as mask, headgear, cartoon
Application on personage and various toys is greatly extensive.The technology that latex generates in tradition is exactly natural emulsion plus some promotors
And pigment.
Such as the patent of invention of Publication No. CN104327321A discloses a kind of latex currently on the market, group is divided into：It
Right 100 parts of latex, 0.4 part of zinc oxide, 2.5 parts of solid paraffin, 0.5 part of casein, 0.4 part of potassium hydroxide, PX0.8 parts of promotor,
3 parts of antioxidant DBH, 5 parts of sulphur, 3 parts of pigment, add up to 115.6 parts, technical conditions are total solids content 50%-52%, chloroform value
In two, 20 ± 5mpa's of viscosity.
But in above-mentioned technical proposal, pigment is not easy to scatter, therefore distribution of color is uneven, results in being made in this way
Rubber product surface shade it is different.
Summary of the invention
The first object of the present invention is to provide a kind of vulcanizate, and product is prepared with distribution of color using the vulcanizate
Uniform advantage.
Above-mentioned technical purpose of the invention technical scheme is that：A kind of vulcanizate, under including
Column parts by weight of component：80~120 parts of natural emulsion；8~20 parts of sulphur；0.8~1.5 part of zinc oxide；0.8~1.5 part of promotor；
4~10 parts of antioxidant；11~25 parts of lanolin；0.8~2.4 part of casein；0.2~0.8 part of ammonium hydroxide；Potassium hydroxide 0.5~1.5
Part；8~13 parts of soft water；18~25 points of dyestuff, 5~15 parts of levelling agent.
Through the above technical solutions, the combined use of potassium hydroxide and soft water, as stabilizer function in recipe ingredient ring
In border, so that system is alkalinity, increases and be mutually dissolved between each component and reaction forward is promoted to carry out；Pass through weight in being formulated
10% casein solution can be prepared in casein, ammonium hydroxide and the soft water of number, and casein solution is added into vulcanizate, and then is adopted
With vulcanizate be made glue product with water imbibition strong, tensile strength and the higher advantage of compression strength, while being resistant to oils and dilute
Acid；It can be painted to natural emulsion by dyestuff, then realization finished product is with certain color, and the levelling agent energy added
Enough so that dye distribution is uniform, the color on finished product is not easy to realize that raising finished color is uniform there are deep mixed phenomenon
The purpose of degree.
The present invention is further：With parts by weight percentages, the promotor includes zinc diethyl dithiocarbamate
30~45%；Zinc dibutyl dithiocarbamate 55~70%.
Through the above technical solutions, zinc diethyl dithiocarbamate is promotor ZDC, dibutyl dithio amino first
Sour zinc is accelerant B C, and the two is used as promotor when natural emulsion vulcanizes, and improves vulcanization timeliness, while coloured mixed
Zoarium system is not easy to be affected and reduce facilitation effect.
The present invention is further：It also include 0.2~0.5 part of nano-silica in terms of parts by weight of component, in said components
Change titanium.
Through the above technical solutions, the vulcanized article surface that production obtains is loose porous, easy adherent bacteria in hole, from
And cause using when it is unhygienic, while also accelerating the aging of silicon rubber.And it is added with a certain proportion of nanometer two in formula
Titanium oxide, nano-titanium dioxide has bactericidal effect, and then can reduce the attachment of vulcanized article surface bacteria, while also can
Slow down the ageing time of rubber.
The present invention is further：It also include 0.4~0.8 part of antibacterial agent DC- in terms of parts by weight of component, in said components
5700。
Through the above technical solutions, antibacterial agent DC-5700 was 3 (trimethoxy silane base) propyl-dimethyl octadecyl seasons
Ammonium chloride, belongs to quaternary ammonium salt bactericide, makes an addition in recipe ingredient, further increases the antibiotic property of production finished product.
The present invention is further：In terms of parts by weight of component, the levelling agent is alkyl polyoxyethylene ether.
Through the above technical solutions, alkyl polyoxyethylene ether also known as paregal O, have the characteristics that it is soluble easily in water, therefore
It can be dissolved in soft water, while there is excellent permeability, be conducive to level dyeing, the diffusion of dye molecule, realize dyestuff in day
It is quickly spread in right lotion, reaches the system uniform as pigment, be finally conducive to the quality for improving finished product.
The second object of the present invention is to provide a kind of preparation method, passes through the preparation method using the vulcanizate of said components
Obtaining product has the advantages that distribution of color is uniform.
Above-mentioned technical purpose of the invention technical scheme is that：It is a kind of to use a kind of above-mentioned sulphur
The method for changing glue preparation vulcanized article, includes the following steps：A, the natural emulsion, sulphur and dyestuff of formula ratio are thrown in presulfurization
Enter into reaction vessel A to be stirred to react progress presulfurization to handle to obtain raw material；B, coagulator is prepared, and will remove natural emulsion and sulphur
Remaining component of the formula ratio of sulphur is put into reactor B, is stirred dissolution and drying process obtains coagulator；C, by step
Obtained in raw material and b step obtained in a coagulator put into sizing material slot be mixed with dipping obtain mixed liquor；D, glue film injection molding is fixed
Type carries out injection process to the mixed liquor in step c using injection molding machine and obtains vulcanized article；E, water vulcanizes foam washing, and vulcanization is made
Product are dipped in 90~110 DEG C of water environment and carry out foam washing.
Through the above technical solutions, realizing that natural emulsion, dyestuff and sulphur in formula react to each other by step a first
Raw material tentatively is obtained, step b during which is carried out to remaining component and operates to obtain coagulator, it then will by glue film injection molding shaping equipment
Obtained mixed liquor handles to obtain vulcanized article, is finally cleaned by water vulcanization foam washing.
The present invention is further：In water vulcanization foam washing step, water environment is the saltwater environment added with 5%NaCl.
Through the above technical solution：In saltwater environment, it is more easier the external residue such as lipid to vulcanized article
Etc. being eluted, the cleanliness on vulcanized article surface is improved.
In summary：The present invention has the advantages that lower：Dyestuff makes an addition in natural emulsion, and the raw material realized has certain
Color, and by levelling agent dyestuff is spread apart and reaches equally distributed effect；Simultaneously be added to nano-titanium dioxide and
Antibacterial agent DC-5700 realizes vulcanized article with certain antibiotic property, and bacterium is not easy to be attached to vulcanized article surface, then
Reach safe and healthy advantage.
