[0022] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0023] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0024] A method for producing water-based PU gloves, comprising:
[0025] Step S1, a step of putting the glove core soaked in the coagulant on the hand mold. Soak the glove core in the coagulant and then put it on the hand mold, or put the dry glove core on the hand mold and then spray it wet with the coagulant. The coagulant is a substance that can cause crosslinking or complexation of the water-based PU resin, including one or any combination of inorganic salts s...

Abstract
The invention discloses a manufacturing technique for aqueous PU (Polyurethane) glove, comprising the following steps: S1, covering a glove core soaked with coagulating agent on a hand module or directly covering a dried glove core on the hand module and then wetting the glove core by the coagulating agent; S2, soaking the glove core covered on the hand mould in the PU slurry so that a PU coating is formed on the surface of the glove, wherein the PU slurry is the aqueous polyurethane resin or mixing slurry prepared by 97%-99.9% of aqueous polyurethane resin and 0.1%-3% of aqueous thickener; and S3, drying or air drying the glove forming the PU coating. The manufacturing technique adopts the aqueous polyurethane resin (aqueous PU resin) without adding any chemical solvent; the aqueous PU glove is non-toxic; the technique is simple; the time for soaking PU coating is shorter; and the manufacturing efficiency is improved.
Description
technical field [0001] The invention relates to a production method of PU gloves, in particular to a production method for forming a layer of water-based PU coating on the surface of a glove core. Background technique [0002] Gloves are widely used in life and work as hand protection tools. The glove core is a safety protective glove impregnated with PU (Polyurethane polyurethane, referred to as polyurethane) resin. The dipping layer is thin, comfortable to wear, has good oil resistance, wear resistance, and low cost. Advantages, it has become an important product in safety gloves in the international market, and sales have continued to rise in recent years. However, the production of such PU impregnated gloves requires the use of dimethylformamide (DMF) as a solvent production process, but DMF has high toxicity, such as DMF residues in gloves, which will irritate the skin after wearing; at the same time, in production The use of DMF as a solvent will affect the health pr...
