Abstract
The invention discloses a polyurethane rubber roller. The polyurethane rubber roller is prepared from the following materials in parts by weight: 50 parts of polytrimethylene glycol, 20-30 parts of toluene diisocynate, 20-30 parts of methanol, 30-40 parts of diethanol amine, 5-10 parts of glycerol, 15-25 parts of 3,3-dichloro-4,4-diaminodiphenyl-methane, 0.5-1.0 part of titanium dioxide and 10-15 parts of spindle oil. The rubber roller is excellent in wear resistance, high temperature resistance, corrosion resistance and antiaging performance, and can be continuously used for 3-4 months under a high-rotation-speed work environment without any change.
Description
Technical field
The present invention relates to a kind of rubber, particularly relate to a kind of polyurethane rubber roller.
Background technology
Polyurethane rubber roller colloid has enough surface viscosities, can ensure rubber roll have in printing process good ink transfer and performance of ink, its good ink-receptive performance can ensure high-quality printing; Appearance luster light, colloid surface is fine and closely woven smooth, colloidal materials and mandrel gluing firm.Rubber roll size strictly controls, and size, under different temperature and humidity conditions, can not vary widely.The hot and humid environment of southern machine room and the weather condition of northern severe cold drying can be adapted to; . polyurethane rubber roller chemical property is good, is applicable to various types of ink and printing process.Special resistance is had to the solvent composition in all kinds of ink, fountain solution, clean-out system.Polyurethane rubber roller is also applicable to UV ink rubber roll and oil polish rubber roll etc., particularly has good solvent resistance to boiling water, diesel oil, gasoline, lubricating oil, kerosene, toluene, alcohol and salt brine solution.But not resistant to acetone, ethyl acetate and strong acid and strong base.
The application of domestic polyurethane rubber roller starts from the beginning of the eighties, and the market requirement increases day by day thereafter.Papermaking, iron and steel, printing and dyeing, in the equipment that the industries such as weaving are introduced, polyurethane rubber roller spare part is badly in need of production domesticization, such as Baosteel rolling mill production line, polyurethane rubber roller accounts for the l/3 of rubber roll total amount, consumption is considerable. and in technological transformation and technical renovation, be badly in need of polyurethane rubber roller replace conventional cots, to enhance productivity, energy efficient, such as drying section of paper machine takes off larger than press part about 10 times of cost needed for 1kg water, if the roll surface material of squeeze roll replaces natural rubber with urethanes, its linear pressure born just can improve 2 ~ 3 times, paper dewatering rate is improved.
According to the Secretariat of association statistics, the impact being subject to production capacity Rapid Expansion except part raw material product show price rises weak except, most of product rate of increase has exceeded more than 10%.Within 2012, national urethane volume of production and marketing reaches 7,800,000 tons, wherein urethane foam volume of production and marketing 3,200,000 tons, spandex 350,000 tons, Synthetic Leather slurry and soles system 1,950,000 tons, polyurethane coating 1,300,000 tons, adhesive for polyurethane and sealing agent 400,000 tons, polyurethane elastomer 600,000 tons, increased by 11.5% than 2011, wherein polyurethane elastomer rate of growth is more than 20%.Account for global ultimate production more than 40% to the urethane volume of production and marketing end of the year in 2012, surely occupy first place in the world.
