Embodiment Construction

[0004] Polyurethane is synthesized from four materials: 1. Polyol; 2. Isocyanate; 3. Chain extender; 4. Catalyst. Polyurethane can be bought domestically, for example, Wanhua Company in Yantai, Shandong produces polyurethane.

[0005] Polyurethane is widely used, for example, in the defense industry, air-tight cushions of various cannons, bulletproof solid tires, anti-skid devices for armored vehicles, etc. In light industry, such as the insulation layer of refrigerators, high-end furniture and shoe soles, etc. Equipment and products made of polyurethane can also be seen in transportation, oil fields, coal mines, construction, sports, and medical fields.

[0006] Textile cots made of polyurethane can avoid the phenomenon of yarn winding cots without coating. This is a new discovery of the performance of polyurethane materials. In addition, textile rubber rollers made of polyurethane have the following advantages over textile rubber rollers made of nitrile rubber:

Abstract

A process for preparing the rubber roller used for textile from polyurethane instead of rubber includes such steps as pre-polymerizing reaction between polyol and isocyanate to obtain NCO-base prepolymer of polyurethane, reacting on the chain-extending cross-linking agent to obtain CPU, installing workpiece on supporting tray, automatic locating, pouring and advancing, closing pouring chamber, vacuumizing, automatic advancing, quantitatively filling, delaying, filling air, opening pouring chamber, taking rubber roller out and curing.

Description

Technical field: [0001] The invention relates to a method for making textile cots with polyurethane. Background technique: [0002] Most of the textile rubber rollers used in the textile industry are made of nitrile rubber, which has a short service life and must be coated with a layer of paint before use. Otherwise, it is easy to appear winding phenomenon. The processing technology is complicated and must be ground with a grinder, which increases the production cost for both the manufacturer and the user of the rubber roller. Invention content: [0003] The purpose of the present invention is to provide a kind of method that can solve above-mentioned technical problem, make novel textile rubber roller with polyurethane. The technical solution adopted is: firstly carry out pre-polymerization reaction of polyol and isocyanate to produce NCO-based polyurethane pre-polymer, and then react with chain-extending cross-linking agent to prepare CPU, and then put the workpiece on...
