Description
Technical field
The present invention relates to safety and industrial gloves technical field more particularly to a kind of foam gloves and its production methods.
Background technique
Polyurethane material is the abbreviation of polyurethanes, and English abbreviation is PU, it is a kind of high molecular material.City at present
It on field when the aqueous PU gloves of production and sales, is made of the sizing material that aqueous PU does not foam, causes the gas permeability of gloves poor, make
User's comfort is very poor, and containing the organic solvent that is harmful to the human body in glove material, and when use will lead to the sweat generated on hand
Liquid can not be discharged to outside in time, and sweat is contacted with gloves, and some toxic organic solvent dissolutions are passed through pore by sweat
It is absorbed by the body.In addition, the aqueous PU feel not foamed is also harder, wearing is inconvenient more uncomfortable.In addition, more commercially available
Aqueous PU gloves, water resistance is very poor, slightly with water wash by rubbing with the hands it is several under be just damaged, resistance to threading is shorter, and service life is very short.

(7) acid resistance, alkali resistance and oil resistivity test result analysis
Infiltration is chemical substance on a molecular scale from the diffusion process of outer surface of glove inner surface.Chemosmosis is usual
It is in the case where gloves material does not have any physical imperfection.The penetration testing of gloves product is usually according to U.S.'s material
What material experiment association criterion (ASTM) or European standard carried out.Permeability test provides the data foundation of two selection gloves: seeping
Saturating time and infiltration rate.
Time of penetration: chemically substance starts to touch the inner surface that chemical substance appears in gloves with the outer surface of gloves
The required time.Time of penetration is to show the important indicator of chemical defence gloves protection against chemical substance, stronger especially for toxicity
Chemical substance.Time of penetration is usually indicated with minute or hour.Permeability test generally only proceeds to 8h, if having arrived 8h also
It is not pierced, then test data is expressed as > 480min or > 8h.The gloves that should select longer time of penetration, especially should
Gloves of the selected area update strategy time in 8h or more.During using gloves, user is it has to be ensured that wear gloves processing chemistry
The time of substance no more than time of penetration, otherwise will be replaced as frequently as gloves.
Infiltration rate: the speed that chemical substance is spread in gloves, infiltration rate usually give gloves face with the unit time
The quality of chemical substance indicates [mg/ (m in product2·min)]。
For selection criteria, most suitable gloves: without apparent aging after contacting with chemical substance, item is being used
There is relatively long time of break-through and lesser infiltration rate under part.
By table 8 and table 9 it is found that the gloves of embodiment 1-24 production are to degradation grade, the time of penetration of different chemicals
It is different with permeability, it is seen that the anti-chemical corrosive power of gloves is stronger, can protect a variety of acid, alkali and esters chemicals, prevent
It is high to protect performance class, protective performance is good.
