Abstract
The present invention provides a polyurethane rubber roller. The present invention is characterized in that the polyurethane rubber roller is prepared from the raw materials of the following mass portions: 100 portions of polytetramethylene terephthalate glycol, 10 to 30 portions of glycerin, 10 to 40 portions of toluene diisocyanate, 20 to 40 portions of triethanolamine, 10 to 25 portions of ethanol, 5 to 15 portions of butanediol, 0.5 to 1 portions of talcum powder and 10 to 30 portions of 3, 3-dichloro-4, 4-diaminodiphenyl methane. The polyurethane rubber roller makes prepared polyurethane products have the performance of supernormal abrasion resistance, high temperature resistance, corrosion resistance, aging resistance, etc., and the price is only 1 to 2 times than that of general rubber. The polyurethane rubber roller especially prepared by the formula has no any change after being used for three months in working environment of high rotation speed and spraying industrial glycerin; while the existing ordinary polyurethane rubber roller is not used because of foaming or severe abrasion after being used for smaller than one month. The synthetic performance of the polyurethane rubber roller of the present invention is also superior to that of foreign similar products, and the polyurethane rubber roller is an ideal product capable of completely substituting imported products.
Description
Technical field
The present invention relates to a kind of high rigidity and elastomeric rubber roll, especially a kind of polyurethane rubber roller between rubber and plastics.
Background technology
The durometer level broad of urethanes, be low to moderate the following low modulus rubber of Shao Er A10, high high impact-resistant resilient material to Shao Er D85, its Young's modulus can be up to hundreds of MPas, well beyond the Young's modulus scope (about 0.2～10MPa) of other rubber, so the performance range of urethanes is very wide, be between the family macromolecule material from rubber to plastics.Also just because of characteristics such as outstanding wear-resisting, the oil resistant of urethane, ageing-resistant, low temperature resistant, high rigidity, snappiness, the consumption of urethane increases sharply in recent years, range of application constantly enlarges, be widely used in industries such as petrochemical complex, mining machinery, light industry and machinery, hydro project, traffic and shoemaking, papermaking, electromechanics, replace and saved a large amount of timber, steel and various rare metal.But the result of use in some particular surroundings such as existing polyurethane rubber roller is not ideal.When especially using under long-time, high speed conditions, it is high temperature resistant, rub resistance, performance such as corrosion-resistant can obviously descend.The urethane part that uses on the overseas high speed cigarette machine as China's import, because of will be under high speed conditions long-play, the wearing and tearing of component are comparatively serious, only be 20～35 days duration of service, not only influences production efficiency, and this type component is entirely by import, therefore, running cost is higher.Therefore, be necessary prior art is improved.
Summary of the invention
The object of the present invention is to provide a kind of polyurethane rubber roller that has high-performance at aspect such as wear-resisting, corrosion-resistant, high temperature resistant.
The present invention realizes by following technical proposal: a kind of polyurethane rubber roller is characterized in that it makes with the raw material of following mass parts:
100 parts of polytetramethylene glycol
Glycerine 10-30 part
Tolylene diisocyanate 10-40 part
Trolamine 20-40 part
Ethanol 10-25
Butyleneglycol 5-15 part
Cornstarch 0.5-1 part
3,3 '-two chloro-4,4 '-diaminodiphenyl-methane 10-30 part.
Above-mentioned raw materials is the commercially available prod.
Compound method:
At first glycerine is joined in the polytetramethylene glycol, be heated to 150-170 ℃, dehydration is 1-2 hour under the vacuum, and reheat is to 150-170 ℃, dewater under the vacuum, three times so repeatedly, when treating that temperature is reduced to 40-60 ℃, add toluene di-iso-cyanide ester, trolamine, ethanol, butyleneglycol, Cornstarch, stirred 2-3 hour, and maintain the temperature at 80 ℃, and carry out vacuum defoamation, add 3 afterwards, 3 '-two chloro-4,4 '-diaminodiphenyl-methane, be poured into die needed in, under 80-150 ℃ of temperature, dry 30-60 minute, behind the shaping and demoulding, sulfuration is 10-15 hour under 50-70 ℃ of temperature, promptly gets product.
The present invention compared with prior art has following advantage and effect: adopt such scheme, the polyurethane products that preparation is come out have extraordinary wear-resisting, high temperature resistant, corrosion-resistant, performance such as ageing-resistant, its wear resistance is 9 times of natural rubber, the over-all properties of its goods is 10 times of rubber item, and price only is 1-2 times of ordinary rubber, especially use the polyurethane rubber roller of above-mentioned formulated, in the Working environment of high rotating speed and spraying industry glycerol, use three monthly any variation not take place, and existing conventional polyurethanes rubber roll, use less than one month can't use because of foaming or heavy wear, its over-all properties is also than external like product excellence, and cost is low, expense is few, is the ideal product that can substitute import fully.
Provide performance of the present invention below:
Relative density: 1.10～1.25 pull apart unit elongation: 500～1000
Shao Er hardness: 10～100 working temperatures :-20～80 ℃
Tensile strength: 0.6～70mpa thermotolerance: excellent
Winter hardiness: winning time epistasis: can
Tear strength: excellent wear resistance: splendid
Ageing resistance: excellent anti-ozone/corona: splendid
Oil-proofness: excellent water tolerance: in
