Abstract
The invention discloses a flame retardant rubber. The composition comprises the following components in parts by weight: 100 parts of neoprene, 1 part of stearic acid, 6 parts of zinc oxide, 4 parts of magnesium oxide, 0.5 part of accelerant NA-22, 30 parts of clay, 20 parts of carbon black N774, 15 parts of naphthenic hydrocarbon oil, and 0-15 parts of aluminum hydroxide. The invention also provides a rubber prepared from the composition, a preparation method and a fire resistance evaluation method. When the dose of aluminum hydroxide is 5 parts, the flame retardant level of the rubber is V-0 and the chemical property is the best.
Description
Technical field
The present invention relates to rubber materials, particularly a kind of flame retardant rubber.
Background technology
In recent years, along with developing rapidly of automotive industry, China presents the situation of quick increase to the demand of rubber, but most of rubber are flammable or inflammable, bring thus the possibility of potential fire generation, directly threatened people's the person and property safety.Meanwhile, the automaker is more and more higher to the rubber item specification of quality that is used in the automobile the inside, particularly combustionproperty.Fire-retardant rubber material refers to delay to catch fire, and reduces voluntarily flame speed, leave behind the external flame can be rapidly from the elastomeric material of horizontal blanking.Researching and developing a kind of flame retardant rubber has great importance.
Summary of the invention
The present invention proposes a kind of flame retardant rubber, has solved to burn to the destruction problem of rubber packing material in the prior art.
Technical scheme of the present invention is achieved in that flame retardant rubber, contains following material and weight part: 100 parts of chloroprene rubbers, 1 part of stearic acid, 6 parts in zinc oxide, 4 parts in magnesium oxide, accelerant N A-220.5 part, 30 parts of clays, carbon black N77420 part, 15 parts of naphthenic oil, aluminium hydroxide 0-15 part.
Preparation method of the present invention is identical with existing method for preparing rubber.
The present invention is by adding the aluminium hydroxide of different amounts, the combustionproperty of research chloroprene rubber.
The invention has the beneficial effects as follows:
(1) the present invention has obtained a kind of flame retardant rubber, can be used in the automobile manufacturing process, plays fire retardation, the possibility of avoiding fire to occur;
(2) the present invention has obtained a kind of fire-retardant rubber item, can be used in the sealing station in the automobile, and the automobile production process is carried out smoothly.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the synoptic diagram of experimental installation of the present invention.
Embodiment
The present invention by adding the aluminium hydroxide of different content, obtains a kind of flame retardant rubber through extensive and deep research, then carries out combustion test, thereby finishes the present invention.Experimental installation of the present invention comprises as shown in Figure 1: rubber mixing mill 10, vulcanizing press 20, rubber slitter 30, corrosion chamber 40.The corrosion chamber 40 that the present invention adopts is internationally recognized UL-94 methods.Combustion test is divided into horizontal firing and vertical combustion, and the present invention adopts the vertical combustion method.This combustion test is divided into three rank: V-0, V-1 and V-2.The V-2 level is minimum fire-retardant rank, and the V-0 level is high flame retardant rank.
The chloroprene rubber rubber
Chloroprene rubber (Neoprene).The synthetic rubber of being produced by the chloroprene rubber polymerization is widely used in for weathering resistance product, viscose glue sole, coating and rocket fuel.Chloroprene rubber is all with emulsion polymerization production, and the technological process of production mostly is single still batchwise polymerization.General types comprises: CR122 type, CR232 type, CR/2441 type, CR321 type.
In order to reach flame retardant properties of the present invention, the present invention has adopted chloroprene rubber CR232 type rubber.
Preferably, described chloroprene rubber belongs to middle Mooney type, crystalline medium type.
Aluminium hydroxide
Chemical formula is Al (OH)
3, be the oxyhydroxide of aluminium.A kind of alkali, owing to show again certain acidity, so can be referred to as aluminic acid (H again
3AlO
3).Aluminium hydroxide is the maximum and most widely used inorganic fire-retarded additive of consumption.Aluminium hydroxide can not only be fire-retardant as fire retardant, and can prevent from being fuming, do not produce dropping, do not produce toxic gas, therefore, obtains to use more widely, and usage quantity is also increasing year by year.Use range: the industries such as thermosetting resin, thermoplastics, synthetic rubber, coating and building materials.
Preferably, described aluminium hydroxide 5000 orders, its fire retardant mechanism is as follows:
Al (OH)
3The fire retardant mechanism of fire retardant is exactly by improving the thermal capacitance of polymkeric substance, making it absorb more heat before reaching heat decomposition temperature, thereby improve its flame retardant properties.The characteristic of a large amount of heat absorptions improved the fire retardancy of himself when this based flame retardant was given full play to it in conjunction with water vapor.
Flame retardance element
Flame retardance element of the present invention comprises:
Below in conjunction with specific embodiment, further set forth the present invention.The experimental technique of unreceipted actual conditions in the following example is measured according to national standard usually.If there is not corresponding national standard, then carry out according to general international standard, normal condition or according to the condition that manufacturer advises.Unless otherwise indicated, otherwise all umbers are weight part, and all per-cents are weight percentage, and described polymericular weight is number-average molecular weight.
Unless otherwise defined or explanation, same meanings of being familiar with of all specialties used herein and scientific words and those skilled in the art.Any method similar or impartial to described content and material all can be applicable in the inventive method in addition.
Comparative Examples:
Select 0,5,10,15 part aluminium hydroxide.
100 parts of chloroprene rubbers, 1 part of stearic acid, 6 parts in zinc oxide, 4 parts in magnesium oxide, accelerant N A-220.5 part, 30 parts of clays, carbon black N77420 part, 15 parts of naphthenic oil, aluminium hydroxide 0,5,10,15 parts, what play fire retardation mainly is chloroprene rubber and aluminium hydroxide.
Processing condition are as follows:
The chloroprene rubber rubber is plasticated in two roller mills, the roller temperature is below 50 ℃, behind the bag roller, add successively stearic acid, carbon black N774, clay, naphthenic oil, aluminium hydroxide, zinc oxide, magnesium oxide and accelerant N A-22, beat triangle bag thin-pass and descend afterwards sheet six times.Before mixing, must keep roller clean, not have contaminated.Use vulcanizing press to carry out one step cure, press vulcanization: 180 ℃ * sulfurizing time of one step cure.Fire retardancy test is to adopt the UL94 corrosion chamber.
Mechanical property and the flame retardant properties of rubber are as shown in the table
As can be seen from the above table, when the aluminium hydroxide consumption surpassed 5 parts, the rubber flame-retarded rank that makes all was V-0, but aluminium hydroxide is when being 5 parts, and its mechanical property is best.
