In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is latex in the embodiment of the present invention by technological process of production schematic diagram.
Embodiment
The purpose of present embodiment is to provide a kind of latex by production technology, and it can effectively solve the problem that prior art
In latex by flexible poor, poor air permeability the problem of.
Hereinafter, embodiment is illustrated referring to the drawings.In addition, embodiments illustrated below is not to described in claim
The content of the invention rise any restriction effect.In addition, the full content of the composition represented by example below is not limited to as right
It is required that necessary to the solution of described invention.
The present embodiment provide latex in production technology, natural emulsion is carried out first to remove ammonia treatment, then again to except
Natural emulsion after ammonia carries out maturation process.Dispensing is then carried out, the natural emulsion after curing carries out dispensing as one of raw material,
Then cured, foamed successively, solidifyingization, vulcanization, washing, drying, cut packaging etc. process.
It should be noted that in the present embodiment, the formula of dispensing is as shown in the table：
Natural emulsion and butadiene-styrene latex ratio can be adjusted according to the requirement of (pure latex) latex quilt, while other auxiliary materials
Can be according to natural emulsion different adjustment carried out in above range with butadiene-styrene latex ratio.
In addition, in the present embodiment, in natural emulsion ammonia-removal process, weight in wet base 2%-4% emulsifying agent and 1%-1.5% are added
Stabilizer, while except ammonia, improve latex stability, until terminating between PH=9-10 except ammonia, now ammonia content both may be used
It to meet gelatinizing process, while can assign compound higher stability, coefficient of foaming etc., the breast of low-density can be produced
Glue quilt.
In proportioning process, in order to make latex by small with hardness, the characteristics of high-flexibility, butadiene-styrene latex selects in formula
With the latex of high butadiene content in polymer, while cooperation foaming agent is added, be preferably such as potassium oleate and castor in the present embodiment
Sesame oil is used with and adds a small amount of chlorion thing, it is possessed excellent foaming capacity and larger coefficient of foaming, the pure breast of in general
Glue quilt, curing temperature control is at 26-30 DEG C, and in 2-6h, the accounting of butadiene-styrene latex is bigger for curing time control, curing temperature and when
Between will properly increase, to reach the technological requirement of latex quilt.
During solidifyingization, gelling agent addition is 3%-5%, and while select slow gelling agent sodium silicofluoride, in glue
Appropriate potassium hydroxide is added in solidifying agent, weakens its acidity, gelatinization is slow, and uniformly, mode of heating is divided into infrared heating
And Hot-blast Heating, latex is required with soft feel, and permeability is strong, so higher infrared temperature is needed, it is excellent
Elect 90-120 DEG C as, the bubble for making surface fine and smooth is not destroyed, and formation is soft, the surface of soft, is completed by hot blast
Overall gelling；
In sulfidation, vapor (steam) temperature is controlled, at the same it is different according to thickness, and cure time accordingly changes, and reaches breast with this
The vulcanization effect of glue quilt；
In stoving process, latex is avoided by the aging caused by high temperature, is aoxidized so as to cause hardness to become big, tensile strength, is broken
Elongation reduction is split, using low temperature drying, with 30-70 DEG C, 25-32HZ hot-air seasoning, latex is possessed high-flexibility
Physical property.
(pure latex) latex quilt of formula and production technology productive experiment more than, physical properties results can be seen that
Density can reach less than 55kg/m3, case hardness can reach less than 9Kpa, and indentation force deflection can reach less than 26Kpa, be really achieved
Low-density, the parameter request of (pure latex) latex quilt of high flexibility.The specific performance of latex quilt is as shown in the table：
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
