Problems solved by technology

Simple addition of small molecule antistatic quaternary ammonium salt antistatic agent, with the increase of washing times, the antistatic agent will gradually migrate, dissolve in water, and lose the antistatic effect; adding conductive carbon black materials can maintain long-lasting antistatic Electrostatic effect, but the carbon black particle material exists independently in the polyurethane material. During the friction process of wearing and using, it will fall off and stain the ground black and cause secondary dust pollution, which is not good for the clean room environment.

preparation example Construction

[0034] Polyols are used as raw materials for the preparation of polyurethane materials. The selection of different polyols has a great influence on the properties of the prepared polyurethane materials. Specifically, polyols include but are not limited to polyester polyols, polyether polyols, and polycarbonate polyols. At least one; further, the polyol is a polyester polyol and / or polyether polyol with a molecular weight of 1500-2500; further, the polyester polyol is a bifunctional carbonate diol, adipic acid Polyester diol; adipate polyester diol is polyethylene adipate, polyethylene propylene adipate, polybutylene adipate or polydiethylene adipate Diol esters; polyester polyols may also contain polyester diols, polyamide polyester diols, and the like obtained by using carboxylic acids, diols, diamines, and the like other than the above in combination. The polyether polyol is a difunctional polyether diol, and the polycarbonate polyol, for example, polyol obtained by esterify...

[0089] The composition of the raw materials for preparing polyurethane shoe soles described in Examples 1 to 5 is shown in Table 1.

[0090] The preparation method of the polyurethane shoe sole described in Examples 1 to 5 is as follows: firstly dry the polyol in raw material A and the isocyanate in raw material B at 70°C respectively for later use, then dry the antistatic agent at 95°C, and add it to the polyol Stir evenly, then add quaternary ammonium salt modified fluorine finishing agent, catalyst, chain extender, foaming agent, foam stabilizer in turn, and mix evenly to form material A; finally mix the mixed material A with the baked material B Mix evenly through a pouring machine, pour into a shoe sole mold to form, after 3 minutes of curing, demould to make easy decontamination antistatic polyurethane material sole.

Abstract

The invention relates to a polyurethane material composition, a polyurethane shoe material and a preparation method thereof. The polyurethane material composition is prepared from raw material A and raw material B. In parts by weight, the raw material A includes the following components: polyol 85-105 parts, 3-5 parts of quaternary ammonium salt modified halothane finishing agent, 2-3 parts of antistatic agent, 1-2 parts of chain extender, 1.5-2.0 parts of catalyst, 0.05-0.1 part of foaming agent and stabilizer 0.05-0.1 part of foaming agent; 110-115 parts of isocyanate in the B raw material. The polyurethane shoe material of the present invention has the functions of stain suppression, easy decontamination, and antistatic function, and at the same time, it can enhance the functions of stain suppression, easy decontamination, and antistatic function, and increase the cleanliness of antistatic shoes; and it will not fall off and cause color fading. The cleaning performance is greatly improved. It is used to prepare anti-static shoes and anti-static boots, matched with anti-static clothing, and used as tooling in a clean room working environment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyurethane material composition, a polyurethane shoe material and a preparation method thereof. Background technique [0002] Anti-static dust-free shoes can be used in purification workshops or clean rooms, and are suitable for enterprises that require high purification levels such as microelectronics, medicine, aerospace, and precision machinery. The anti-static clothing in the purification workshop is made of chemical fiber filaments. During the work of the staff, the friction between the body and the clothing will generate a lot of static charges. These static charges need to be grounded through the anti-static shoes connected to the anti-static clothing. , to release the generated static charge, otherwise it will cause great damage to electronic components. [0003] The sole base material of anti-static shoes is polyurethane or PVC. The price of PV...
