Abstract
The invention discloses a method for preparing the protective material of toxic and harmful substances, and aims to provide a material capable of comprehensively protecting toxic and harmful substrates such as bacteria, strong acid, strong base, toxic gas and the like and being combined with flexible preparation to be used. The method disclosed by the invention comprises the following steps: (1) mixing: sequentially adding magnesium oxide, stearic acid, an antistatic agent, decabromodiphenyl ether, liquid chlorinated paraffin, aluminum hydroxide, an accelerating agent and sulphur to be mixed and vulcanized after chlorhydrin and nitrile butadiene rubber at the plastication are rolled, thereby obtaining mixing rubber; and (2) scraping: adding the mixing rubber to a solvent; selecting cotton cloth as a framework material after being mixed and scraping the stirred mixing rubber on the surface of the framework material by adopting the existing scraping process, thereby obtaining a finished product. The method disclosed by the invention has the advantages of simple and convenient operation and easy popularization, and the product can effectively prevent the toxic and harmful substrates such as the bacteria, the strong acid, the strong base, the toxic gas and the like from penetrating and can be widely used for the storage and destruction of antitoxin clothes, protective tents, protective turnaround bags and harmful substrates.
Description
Technical field
The present invention relates to the preparation method of protective materials, be specifically related to a kind of preparation method of poisonous and harmful substance protective materials.
Background technology
The protective materials of present poisonous and harmful substance, in use, have following defective: one, majority can not be combined with flexible article all take rigidity as main, in use brings inconvenience; Two, can't effectively isolate pollution sources, personnel mainly adopt hide, the adapted individual protection equips to protect, easily secondary pollution causes vehicle and personnel's consumption to increase; Three, be not suitable for processing to biological pollution, cause easily pollution in wide area.
The above defective that exists in order to eliminate existing protective materials is carried out integrated protection with regard to the needs research and development are a kind of to venomous injurant mass-energy such as bacterium, strong acid and strong base, poison gases, and the material that can be combined with the flexibility preparation.
Summary of the invention
The purpose of this invention is to provide and a kind of the venomous injurant mass-energy such as bacterium, strong acid and strong base, poison gas are carried out integrated protection, and the material that can be combined with the flexibility preparation, and a kind of preparation method of poisonous and harmful substance protective materials is provided.
The present invention is achieved by the following technical solutions:
A kind of preparation method of poisonous and harmful substance protective materials may further comprise the steps:
(1) mixing: on opening rubber mixing machine, first chloropharin glue and butadiene acrylonitrile rubber are plasticated, the mass ratio of chloropharin glue and butadiene acrylonitrile rubber is 60:40, and part adds each component of following weight portion successively behind its bag roller:
Magnesia 3, stearic acid 2, antistatic additive 7, deca-BDE 10, liquid chlorinated waxes 5, aluminium hydroxide 10, promoter 1, sulphur 2,
Carry out mixing, mixing evenly after lower sheet, sulfuration namely gets elastomeric compound;
(2) blade coating: it is 2-3m that the elastomeric compound that mixes is pressed into thickness in Φ 400mm mill, be not more than the film of 400 * 400mm, pack in the mixer, then add solvent, stir 4-6h, then select polyester-mixed cotton cloth as framework material, adopt existing blade coating technique, the elastomeric compound blade coating that stirs is surperficial at framework material, get product.
The electrical heating air cure is adopted in described sulfuration.
Described solvent is gasoline or acetic acid.
Described framework material is 2 layers, 3 layers of elastomeric compound of blade coating.
After the mixing end, carry out the coating procedure of rubber, present coating procedure mainly contains blade coating, impregnation, inserts several process routes such as glue, rubberizing, characteristic needs according to product, carried out performance comparison, selected blade coating, blade coating can well guarantee the presentation quality of product, so that rubber molecular chain comparatively is evenly distributed in the surface of casing play, reach good combination with casing play.
Rubber molecule is coated in the surface of casing play uniformly, casing play mainly plays forceful action, rubber layer mainly plays function, so this just requires that suitable adhesive force is arranged between casing play and rubber molecule, the size of adhesive force directly affects the final effect of product, the too small delamination that occurs easily, excessively bring larger difficulty to technological operation, so prescription, selecting of casing play is just very important, process is to 514,517,504, the multiple yarn fabric such as polyester-mixed cotton cloth carries out powerful contrast test, although the brute force of polyester-mixed cotton cloth is lower, but better with the degree of adhesion of glue-line, so select polyester-mixed cotton cloth as framework material, can well solve rubber molecule and be combined with casing play.
The properties of the protective materials of the poisonous and harmful substance that foundation the inventive method is obtained is tested, wherein there is respectively GJB535-88 impermeable protective clothing material that mustard gas " liquid-gas " protection time is measured, HGB-1255-79 impermeable protective clothing adhesive plaster breaking strength assay method, GB5455-85 fabrics flame resistance performance measurement-normal beam technique, indices is as shown in table 1:
Table 1
| Project | Index |
| The gas defence performance | ≥4h |
| The bacteriological protection powder | Do not reveal |
| Resistance to acids and bases | ≥4h |
| Water penetration | The hydrostatic pressing water-column is greater than 500mm, and is waterproof |
| Warp-wise is pulled apart brute force | ≥600N／50mm |
| Broadwise is pulled apart brute force | ≥400N／50mm |
As can be seen from Table 1, the product according to the inventive method obtains has very high intensity, and putting poison property, resistance to acids and bases and air-tightness are good, are a kind of materials that carries out integrated protection.
Compared with prior art, the present invention is easy and simple to handle, be easy to promote, the product that obtains according to the inventive method can prevent bacterium effectively, strong acid and strong base, penetrating of the poisonous and harmful substances such as poison gas, the employing specific rubber is basic material, utilize the long advantage of the initial strand of rubber, in prescription, sneak into other system, in mixing process, strand has fully been interrupted, carried out the molecule cross reaction with vulcanizing system, form the fine and close netted knot in space, when poisonous and harmful substance penetrates, can form barrier, prevention is passed through, of many uses, can be used for frog suit, protecting tent, the protection turnover bag, harmful substance is preserved, destroy etc.
