Abstract
The invention discloses a variable-wall-thickness glove preparation method and a pair of gloves prepared with the method, and belongs to the field of preparation of protective devices. A coagulant with different concentration is applied to different positions of a glove mold, and one-time total impregnation with rubber emulsion is performed, so that variable wall thickness is realized at any part of the gloves. Special processing of the glove mold is not needed, and local thickening can be realized with adoption of the conventional glove mold, so that the flexibility of the gloves is guaranteed on the premise that the protection requirements are met. The method has greatly high adaptability, the flexibility of the prepared gloves can be guaranteed on the premise that the protection requirements are met, and the operation feel of a user is improved. Radiation protective gloves prepared with the method can protect the hand back of a doctor in a interventional therapy environment or other environments and can particularly meet the requirements for protection against X-rays, gamma-rays and neutrons, and the gloves can integrate the characteristics of protection and flexibility in use on the premise that the hand back of the doctor under an interventional therapy is protected effectively.
Description
Technical field
The present invention relates to protective device preparation field, especially radiation protection product scope, be specially one and become wall thickness glove system
Preparation Method and the glove of preparation thereof.The present invention can realize glove not by a mass-impregnation on the basis of existing mold
Prepare with the change wall thickness at position.Use change wall thickness protective gloves prepared by the present invention, especially become wall thickness X-ray protection glove,
Can be used in the protection to doctor's the back of the hand position in intervention operation and bone surgery, there is preferable protection effect and application prospect.
Background technology
In nuclear industry and the field of nuclear medicine, the radiation protection rubber gloves used is to wait wall thickness glove.Lead on wall thickness glove
Frequently with general glove mould, it is prepared from by the way of mass-impregnation.In order to reach preferable protection effect, adopting
When the wall thickness glove such as preparing by ordinary glove mould mass-impregnation method, need to add the wall thickness of large glove;Thus, prepared hands
Set is the most thick and heavy, when using or perform the operation, can affect the operating handle of doctor, and then the corresponding operation of impact.
Chinese patent CN201010202804.1 discloses a kind of radiation-proof rubber protective gloves and preparation method thereof, and it can realize
Decay to X-ray about 50%.But, practice have shown that: in order to reach preferable protection effect, this protective gloves needs
That does is thicker.Therefore, this protective gloves is only suitable to simple operations, it is impossible to be used for getting involved the accurate operations such as operation, bone surgery.
In order to solve foregoing problems, inventor's one becomes wall thickness radiation protection glove (application number: 201520612087.8), its
By the local of glove is repeatedly impregnated, thus realize becoming the preparation of wall thickness protective gloves.
Meanwhile, inventor also disclose a kind of for prepare become the female mold of wall thickness glove and preparation thereof glove (application number:
201510831861.9).This invention is mainly by the improvement of mould itself, thus realizes glove change wall thickness and prepare.It realizes
The mechanism that glove become wall thickness is based primarily upon three aspects: one is owing to the groove of mould can accommodate more latex, it is achieved thicken;Two
It is owing to the hydrophilic of groove surfaces is more preferable, more latex can be loaded;Three is owing to the hydrophilic of groove surfaces is more preferable, can bear
Carry more coagulator, coagulator good water absorption, more latex after Dipped latex, can be loaded.
In order to preferably simplify the preparation becoming wall thickness glove, inventor provides a kind of new change wall thickness glove preparation method and system thereof
Standby glove.
Summary of the invention
Applicant is found by research, X-ray, gamma-rays, neutron radiation application in, X-ray, gamma-rays, neutron
The most direct and serious to the irradiation damage at operator's the back of the hand position.And existing wait wall thickness protective gloves in use, flexibly
Property poor, it is impossible to meeting the needs of doctor's finger flexible operating, therefore, doctor is often reluctant to wear and existing waits wall thickness lead to prevent
Hand guard glove.Therefore, in the urgent need to exploitation one, there is preferable radiation protection effect, flexible accurate operation requirement can be met again
Protective gloves, i.e. becomes wall thickness glove.
The goal of the invention of the present invention is: for the problem of above-mentioned existence, it is provided that a kind of change wall thickness glove preparation method and system thereof
Standby glove.The present invention by coating the coagulator of variable concentrations at the different parts of glove mould, and is soaked by once overall
Stain rubber latex such that it is able to realize becoming wall thickness to any position of glove.The present invention is without carrying out special adding to glove mould
Work, uses existing glove mould can realize local and thickeies, thus on the premise of effectively protection, it is ensured that glove flexible
Property.The present invention has extremely strong adaptability, and prepared glove can be on the premise of meeting requirement of shelter, it is ensured that glove
Motility, improves the operating handle of user.The radiation protection gloves using the present invention to prepare disclosure satisfy that the rings such as intervention operation
Protection to doctor's the back of the hand under border, enables in particular to meet the protection needs of X-ray, gamma-rays, neutron, and it can be to intervention
Operative doctor the back of the hand effectively protect in advance under, it is ensured that finger manipulation operation motility, effectively take into account protection and use
Feature flexibly.The present invention is reasonable in design, easy to use, uses a mass-impregnation can prepare change wall thickness glove, tool
There is preferable application prospect, for becoming the preparation of wall thickness glove, there is important directive significance.
To achieve these goals, the present invention adopts the following technical scheme that
