Abstract
The invention provides a waterborne polyurethane resin for examination gloves, which comprises the following components in parts by weight: 15-40 parts of diisocyanate, 80-120 parts of polyol, 0.03-0.08 part of catalyst, 3.5-7 parts of chain extender, 20-50 parts of diluent, 0-5 parts of neutralizer, 250 parts of water and 1-7 parts of amine chain extender. The raw materials of the waterborne polyurethane resin for the examination gloves are more polyester polyol, and the synthesized waterborne polyurethane has high tensile strength, high elongation, good air permeability, soft material and high wearing comfort after being made into the gloves.
Description
Technical Field
The invention belongs to the technical field of materials, and particularly relates to a waterborne polyurethane resin for examination gloves and a preparation method thereof.
Background
In the prior art, the materials of the examination gloves are mainly classified into four types, namely PVC, butyronitrile, latex and polyurethane, and the examination gloves made of the materials respectively have the following defects: 1. PVC inspection gloves: the examination glove of the type has low elongation, poor strength, poor air permeability, residues of o-benzene solvents and low wearing comfort; 2. nitrile rubber examination gloves: the examination glove of the type has low elongation, general strength, poor air permeability, hard material and low wearing comfort; 3. latex examination gloves: the examination glove of the type has low strength, contains small molecular proteins, is easy to cause allergy, and has poor air permeability; 4. polyurethane examination gloves: polyether polyols are used as raw materials for the examination gloves of this type, and the tensile strength and the elongation at break of the gloves after the gloves are made are all below 60MPa and below 600% (the tensile strength and the elongation do not reach the data at the same time), and the tensile strength and the elongation are not satisfactory.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide an aqueous polyurethane resin for examination gloves and a method for preparing the same. The obtained waterborne polyurethane resin for the examination gloves has stronger tensile strength and larger elongation at break after being cured.
The purpose of the invention is realized by the following technical scheme:
the invention provides a waterborne polyurethane resin for examination gloves, which comprises the following components in parts by weight:
