Abstract
The invention discloses a knee pad rubber and a preparation method and application thereof. According to the formula, the knee pad rubber consists of the following components in part by weight: 40 to 60 parts of natural rubber 3L, 27 to 30 parts of filling agent, 10 to 15 parts of softening oil, 7 to 10 parts of accelerants, 1 to 2 parts of defoaming agent, 2 to 3 parts of quick vulcanizing agent and 1 to 2 parts of sulfur. White carbon black and calcium carbonate serving as accelerants are introduced into the formula of the knee pad rubber for the first time and simultaneously matched with the softening oil, so that the white carbon black and the calcium carbonate are not hard any more; and under the action of the softening oil, the white carbon black and the calcium carbonate endow the knee pad rubber with good smoothness, hard object scratch resistance and flexibility, and the knee pad rubber has unexpected advantages. The knee pad rubber has the advantages of good heat insulation property, good elastic restoration, high crease resistance, seawater soaking resistance, flexibility and hard object scratch resistance, and can be applied to the knee or the elbow of sport suit or diving dress.
Description
Technical field
The present invention relates to rubber materials, be specifically related to the submarine armor rubber materials, relate in particular to a kind of knee-pad rubber of protecting submarine armor shank knee and ancon, and the preparation method of this knee-pad rubber.
Background technology
The frogman need slip into the deep-sea, and temperature is very low in the deep-sea, and corrosive properly is big; and environment is relatively more dangerous; usually can bring damage to submarine armour as hard things such as corals, therefore, the temperature tolerance of submarine armor, erosion resistance, anti-hard thing scratch performance requriements all than higher.
In addition, the frogman is owing to needing operation under water, so shank knee and ancon often need bending, this just requires very high to the elastic reset of submarine armor, therefore, the submarine armor that can help the flexible operation of frogman more just can be subjected to frogman's welcome more, and its market is also just wide more.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of good heat preservation performance, good, the height folding of elastic reset, the knee-pad rubber that sea water resistance soaks and anti-hard thing scratches.
Another object of the present invention is to provide the preparation method of above-mentioned knee-pad rubber.
Another object of the present invention is to provide the application of above-mentioned knee-pad rubber.
Above-mentioned purpose of the present invention is achieved by following scheme:
A kind of knee-pad rubber, its composition of raw materials is made up of each component of following parts by weight:

Above-mentioned natural rubber 3L is the commercially available prod, adopts commercially available any natural rubber 3L all can realize the present invention.
Above-mentioned weighting agent is an auxiliary agent commonly used in the rubber preparation process, and any weighting agent that adopts those skilled in the art to carry out being used always when rubber prepares all can be realized the present invention, as kaolin, carbon black, white carbon black (white cigarette), potter's clay or lime carbonate etc.;
In the above-mentioned weighting agent, white carbon black and lime carbonate mostly are the used weighting agent of shoemaking, the inventor finds by the research back, white carbon black and lime carbonate arranged in pairs or groups be used to prepare knee-pad, under the effect of softening oil, original harder " white carbon black+lime carbonate " collocation becomes very soft on the contrary, and give smooth, anti-hard thing scuffing of knee-pad and soft characteristic, so the mixture of preferred white carbon black of weighting agent of the present invention and lime carbonate.
The effect of above-mentioned softening oil is to make that rubber is soft more and be rich in good elasticity, and in the present invention's prescription, softening oil mainly is and weighting agent collocation, especially white carbon black and lime carbonate, thereby harder weighting agent is become soft; Any softening oil that softening oil of the present invention adopts those skilled in the art to carry out using always when rubber prepares all can be realized the present invention, as paraffin oil, naphthenic oil or aromatic hydrocarbons wet goods.
Above-mentioned promotor is carried out the auxiliary agent used always when rubber prepares for those skilled in the art, any promotor commonly used all can be realized the present invention when adopting rubber to prepare, as any one or two or more the mixing in zinc oxide, magnesium oxide, plumbous oxide, stearic acid, antioxidant, accelerator M, accelerator D, accelerator H or the accelerator ZBX etc.
Above-mentioned defoamer carries out the auxiliary agent used always when rubber prepares for those skilled in the art, and any defoamer commonly used all can be realized the present invention when adopting rubber to prepare.
The effect of above-mentioned high-speed vulcanization agent mainly is to make each raw material of this prescription well-done in the following short period of time of state at the high sulfurized of low speed, raises the efficiency the shortening time; The high-speed vulcanization agent also is that any high-speed vulcanization agent of adopting those skilled in the art to carry out using always when rubber prepares all can realize the present invention, as high-speed vulcanization agent DPTT, high-speed vulcanization agent TRA or high-speed vulcanization agent CBO.
Above-mentioned sulphur plays sulfuration.
The preparation method of above-mentioned knee-pad rubber specifically comprises the steps:
With natural rubber 3L after mill was smelt ripe glue in 15～35 minutes, in this ripe glue, add weighting agent, softening oil, promotor and defoamer, mix stirring through mill, temperature is controlled between 30 ℃～35 ℃, churning time is 10～30 minutes, is smelt glue, adds sulphur and high-speed vulcanization agent at last again, 80 ℃～120 ℃ were evenly stirred 2～6 minutes, then prepare required knee-pad rubber.
Above-mentioned preparation gained knee-pad rubber is found through performance test, and this knee-pad rubber good heat preservation performance, elastic reset are good, height folding trace, sea water resistance soak, flexibility is good, and draws the damaged situation that do not have energetically with ironware hardware thing.
Knee-pad rubber of the present invention can be used for shank knee or the ancon on the special industry clothes, as the shank knee or the ancon of the shank knee of Sportswear or ancon, submarine armor.
Compared with prior art, the present invention has following beneficial effect:
1. the inventor screens by the composition of raw materials to knee-pad rubber, finally obtain a kind of preparing and have good heat preservation performance, elastic reset is good, height folding trace, anti-sea water immersion, the knee-pad rubber raw materials prescription of premium propertiess such as soft and anti-hard thing scuffing, especially in composition of raw materials, introduce white carbon black and lime carbonate in the raw material of knee-pad rubber as promotor first, the softening oil of arranging in pairs or groups simultaneously, not only white carbon black and lime carbonate are no longer hard, and these two kinds of materials are under the effect of softening oil, give knee-pad rubber good slipperiness, anti-hard thing scratch resistant and flexibility have played beyond thought beneficial effect;
2. the inventor is also at the composition of raw materials of knee-pad rubber, time in its preparation process and temperature parameter optimized, thereby guaranteed the premium properties of knee-pad rubber.
