Abstract
The present invention relates to a polyether liquid rubber and its production method. Its basic composition includes (weight ratio) polyether mother liquor 100, diisocyanate 18-25, three-white body 18-25, hydrophobic oleic acid 0.1-0.3 and crosslinking agent 8-15, in which the described three-white body is composed of (weight ratio) titanium pigment 8, white carbon black 12, light calcium carbonate 6, polyether 10-15 and diisocyanate 1.8-2.5. Said invention is low price in raw materials, simple in production process, can be used for producing ship board-protective products with various shapes, also can be used for producing various products with high anti-abrasion and high strength, such as hydraulic component, etc..
Description
The present invention relates to a kind of elastomeric material and production method, especially a kind of polyether liquid rubber and production method that is suitable for making fender product peculiar to vessel.
At present, the fender product peculiar to vessel of China is more backward.Have plenty of and use inflatable rubber item, have plenty of the use coir rope, the former can be because powerful bump, and produces the gas phenomenon of stopping, and the latter then can be big owing to accumulateing the water yield, and coir rope is rotted.The ship that has then uses waste and old doughnut to serve as fender product, and not only intensity is low, but also influences the attractive in appearance of ship.For this reason, people just work out many materials and produce fender product, as polyester rubber, polylactone rubber, pyrene sesame oil rubber etc., but the fender product of being produced does not still reach the standard-required of fender product peculiar to vessel on index such as wear-resisting, ageing-resistant, corrosion-resistant.
The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of polyether liquid rubber and production method that is suitable for making fender product peculiar to vessel is provided.
Above-mentioned purpose of the present invention realizes by following technique means.A kind of polyether liquid rubber, its basal component weight ratio is:
Polyethers mother liquor 100
Vulcabond 18～25
Three lean types 18～25
Hydrophobic oleic acid 0.1～0.3
Linking agent 8～15
The components by weight of described three lean types is:
Titanium dioxide 8
White carbon black 12
Light calcium carbonate 6
Polyethers 10～15
Vulcabond 1.8～2.5.
Also contain chromatoplast in the described component.
The production method of polyether liquid rubber comprises the steps:
A. the polyethers mother liquor is inserted and vacuumize 2 hours～3 hours in the encloses container, simultaneously the polyethers mother liquor is heated to 100 ℃～120 ℃, and it is stirred with agitator;
B. quantitative vulcabond is heated to more than or equal to 30 ℃, is less than or equal to 50 ℃; Then it is mixed with the polyethers mother liquor, more than or equal to 60 ℃, be less than or equal under 90 ℃ the temperature, stir, form and give aggressiveness, stand-by;
C stirs quantitative titanium dioxide, white carbon black and light calcium carbonate and dries, and forms three white powder, and getting the quantitative polyethers that has exhausted vacuum is thinner, and gets quantitative vulcabond and three white powder are inserted ball milling in the ball mill jointly, forms three lean types;
D. get quantitative three lean types and give aggressiveness and mix, be heated to 70～80 ℃, and stir; Add wherein with quantitative hydrophobic oleic acid is common after getting quantitative linking agent heat fused again, be heated to 70 ℃～80 ℃, stir simultaneously.
In described c step, also can add chromatoplast, stir with other component.
Polyether liquid rubber provided by the present invention and production method, material is cheap, production technique is simple, by polyether liquid rubber provided by the present invention and production method,, can produce the fender product of different shape by die casting, also can be as required, and produce variously to demanding products such as wear-resisting, intensity, as hydraulic part etc., the product of being produced has following advantage:
1. in light weight, buoyancy is big;
2. intensity height, good springiness, intensity generally can reach 422Kg/cm
2
3. tear resistance is good, and tear strength can reach 68Kg/cm
2
4. hardness height, wear resisting property are good, can be 7 times of natural rubber;
5. corrosion resistant, oil resistant, anti-ozone and ageing-resistant performance are good;
6. high temperature resistantly reach 100～150 ℃;
7. low temperature resistantly reach-70 ℃.
Introduce the utility model specific embodiment below in detail.Embodiment 1, gets polyethers mother liquor (N-220) 100Kg, inserts in the vacuum tank, be provided with mixing tool and heating unit in the vacuum tank, the polyethers mother liquor vacuumized 2 hours, when vacuumizing, the polyethers mother liquor is heated to 100 ℃, and stirs, get vulcabond (TDI-2080) 18Kg with agitator, be heated to 30 ℃, mix with the polyethers mother liquor then, under 60 ℃ temperature, stir, aggressiveness is given in formation, parks 6 hours, and is stand-by; Get 8Kg titanium dioxide (TiO
