Description
Technical field
The present invention relates to a kind of fire-retardant material and preparation method thereof.Specifically, be the preparation method with fire-proof heat-resistant soft rubber of fire resistance.
Background technology
As everyone knows, no matter at industrial circle or daily life field, for avoiding the generation of fire, all can relate to fire safety problem, all need refractory materials.Traditional refractory materials has asbestos, glass fibre, pre-oxygen silk and aramid fiber etc., can be made into asbeston or various utensil with these materials, to adapt to the fire protection requirement of different industries.Asbestos are wherein forbidden by countries in the world with easily carcinogenic after human body contacts.The cloth that is made into glass fibre with skin is itched after human body contacts, also unfavorable to health.Pre-oxygen silk and aramid fiber 8 ~ 300,000 yuan/ton, price comparison is expensive, and pre-oxygen silk is more crisp, and aramid fiber is sacrifices consisting of an ox, a sheep and a pig again, the processing relatively difficulty of getting up all.And pre-oxygen silk and aramid fiber China do not have the source of goods, and dependence on import is difficult to form the batch production scale fully.In addition, the fire resistance rating of above-mentioned several fire-retardant materials only has
B1Level, fire performance is relatively poor, and for example, glass fibre will melt under 600 ℃ of temperature, and pre-oxygen silk and aramid fiber respectively will carbonizations under greater than 260 ℃ of temperature and under 240 ℃ of temperature, are difficult to satisfy the occasion that higher fire-proof and thermal-insulation requirement is arranged.
Summary of the invention
The problem to be solved in the present invention provides a kind of fire-proof heat-resistant soft rubber.The fire-retardant material that this fire-proof heat-resistant soft rubber is used, price is low, the source of goods is sufficient, harmless.With asbeston and various utensil that this fire-proof heat-resistant soft rubber is made, fire performance is good, can satisfy the occasion that higher fire-proof and thermal-insulation requirement is arranged.
Another problem that the present invention will solve provides a kind of method for preparing fire-proof heat-resistant soft rubber.
For addressing the above problem, take following technical scheme:
The characteristics of fire-proof heat-resistant soft rubber of the present invention are that the raw material by following parts by weight consists of:
70 ~ 100 parts of chlorinatedpolyethylenees;
0 ~ 20 part of butadiene-styrene rubber;
0 ~ 20 part of cis-butadiene cement;
0.5 part in zinc oxide;
0.5 ~ 2 part of stearic acid;
5 ~ 15 parts in magnesium oxide;
20 ~ 80 parts of magnesium hydroxides;
20 ~ 80 parts in aluminium hydroxide;
30 ~ 50 parts of white carbon blacks;
1 ~ 5 part of glycol ether;
1 ~ 10 part of barium stearate;
1 ~ 10 part of Zinic stearas;
0.5 ~ 3 part of 2 mercapto benzimidazole;
0.5 ~ 3 part of styrenated phenol;
2 ~ 10 parts of antimonous oxides;
1 ~ 5 part of dicumyl peroxide;
1 ~ 5 part in isocyanuric acid three allyl fat;
0 ~ 10 part of titanium dioxide;
0 ~ 10 part of mica powder.
The method for preparing above-mentioned fire-proof heat-resistant soft rubber may further comprise the steps:
First chlorinatedpolyethylene, butadiene-styrene rubber, cis-butadiene cement, zinc oxide, stearic acid, magnesium oxide, magnesium hydroxide, aluminium hydroxide, white carbon black, glycol ether, barium stearate, Zinic stearas, antimonous oxide, isocyanuric acid three allyl fat, titanium dioxide and mica powder are put into the machine of beginning to pratise, under 70 ~ 80 ℃ temperature mixing 18 ~ 25 minutes;
Add again 2 mercapto benzimidazole, styrenated phenol and dicumyl peroxide, under 70 ~ 80 ℃ temperature mixing 3 ~ 10 minutes, obtain fire-proof heat-resistant soft rubber.
Take above scheme, have the following advantages:
Chlorinatedpolyethylene, butadiene-styrene rubber, cis-butadiene cement, zinc oxide, stearic acid, magnesium oxide, magnesium hydroxide, aluminium hydroxide, white carbon black, glycol ether, barium stearate, Zinic stearas, antimonous oxide, isocyanuric acid three allyl fat, titanium dioxide, mica powder, 2 mercapto benzimidazole, styrenated phenol and dicumyl peroxide etc. are arranged owing to the present invention is raw materials used, do not contain asbestos and glass fibre, harmless.Because the present invention in advance oxygen silk and aramid fiber, not only price comparison is cheap, and is convenient to process again.In addition, above-mentioned several raw materials all are the traditional chemical raw materials, and domestic ample supply and prompt delivery do not need import, form easily the batch production scale.In order to verify the fire performance of fire-proof heat-resistant soft rubber of the present invention, we have done following several tests: the one, and the fire-proof heat-resistant soft rubber made from method of the present invention is through over cure, the thin slice of 200 * 200 * 2.5mm that makes, drop in the ladle of 1500 ~ 1600 ℃ of temperature, though curling phenomenon is arranged, but take out Deng after 10 seconds, still can return to original state; The 2nd, with the gas flame welding gun of 1500 ~ 1600 ℃ of temperature, (200 * 200 * 2.5mm) thin slice flames about 10 seconds, this thin slice does not have breakdown the distance about 10 centimeters facing to fire-proof heat-resistant soft rubber of the present invention; The 3rd, (200 * 200 * 2.5mm) thin slices carry out the cutting test of 5 seconds, and only there are some carbonization phenomenons on the otch both sides on this thin slice about 5 centimeters, do not have combustion phenomena to fire-proof heat-resistant soft rubber of the present invention with the burning torch of 3200 ℃ of temperature.This shows that fire-proof heat-resistant soft rubber of the present invention, fire performance are good especially.Therefore, make again various asbestons or various Work tool with fire-proof heat-resistant soft rubber of the present invention, can satisfy the occasion that very high fire-proof and thermal-insulation requirement is arranged.
