Abstract
The invention discloses a sizing formula of a flame-retarding elastic support rubber product. The sizing formula is characterized in that components of the rubber product are as follows (parts by mass of each component are shown in brackets): 21-type-322 neoprene (25-35), standard 1# natural rubber (65-75), zinc oxide (7-9), light magnesium oxide (4-6), sulfur (0.1-1.0), an accelerant CZ (1.3-1.7), an accelerant Na-22 (0.4-0.6), an ageing inhibitor 4,010 (0.8-1.2), 2,500-mesh diantimony trioxide (15-25), 2,500-mesh aluminium hydroxide (50-60) and semi-reinforcing carbon black (10-20). In the invention, unvulcanized rubber is a combination of the neoprene and the natural rubber, a vulcanizing system is a combination of metal oxide and the sulfur, a flame retardant is a combination of the diantimony trioxide and aluminium hydroxide, and the semi-reinforcing carbon black is used for reinforcing; therefore, the prepared rubber product has good physicochemical properties, especially has high oxygen index and low smoke index. The invention is applicable to preparing the elastic support rubber product used between a floor board and a floor board framework when floor boards are laid in a public place and on a passenger train, a subway as well as a bus.
Description
Technical field
The present invention relates to a kind of sizing compound formula of elastic support rubber product, rubber and auxiliary agent in particularly a kind of sizing compound formula of the elastic support rubber product with flame retardant properties.
Background technology
Rubber item is to cooperate certain auxiliary agent to form through mixing, sulfuration by rubber.Rubber item has elasticity preferably, has damping performance, and in rubber item, some rubber items are elastic support rubber products of using as damping, such as when the laying floor between floor frame and floor as the resiliency supported pad.Elastic support rubber product between floor frame and floor should have certain intensity, elasticity, hardness, physical and chemical performance such as anti-aging.Be equipped with the floor on ground such as some public places, passenger train, subway, buses, fire safety for these public places, caoutchouc elasticity supporting pad between floor frame and floor supports above-mentioned certain intensity that goods had, elasticity, hardness, the physical and chemical performance such as anti-aging and also should have flame retardant properties and smoke elimination performance except having caoutchouc elasticity, and higher oxygen index and lower smoke index promptly should be arranged.In the prior art, the sizing compound formula of elastic support rubber product is just in order to satisfy the needs of damping, the caoutchouc elasticity made supports goods and only has the certain intensity that meets damping and use, elasticity, hardness, physical and chemical performance such as anti-aging, do not possess flame retardant properties and smoke elimination performance, its oxygen index is lower, smoke index is higher, be not suitable for when the laying floor of ground such as the public place that fire protection requirement is arranged, passenger train, subway, bus, supporting goods as the caoutchouc elasticity between floor frame and the floor.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, when proposing ground such as a kind of public place that is adapted at fire protection requirement, passenger train, subway, bus laying floor, as the sizing compound formula of the flame-retarding elastic support rubber product between floor frame and the floor.
The present invention is achieved using the following method.
The composition of the sizing compound formula of flame-retarding elastic support rubber product and the mass parts of each composition are:
21 types-322 chloroprene rubber: 25～35, standardized component 1# natural gum: 65～75, zinc oxide: 7～9, light magnesium oxide: 4～6, sulphur: 0.6～1.0, accelerant CZ: 1.3～1.7, accelerant N a-22:0.4～0.6, antioxidant 4010: 0.8～1.2,2500 order antimonous oxides: 15～25,2500 order aluminium hydroxides: 50～60, semi-reinforcing hydrocarbon black: 10～20.
The present invention has following characteristics:
1. the rubber in this prescription has adopted high Mooney polychloroprene rubber for general purpose and two kinds of rubbers of natural gum and has used, neoprene latex has excellent flame-retardant performance, higher physical strength, autohension and excellent aging resistance preferably, but chloroprene rubber contains the halogen group element can make the smoke index of rubber item higher, and used natural gum to make the processing performance of sizing material good, make powerful high, the good springiness of rubber item, particularly can reduce smoke index;
2. fire retardant is taked antimonous oxide and two kinds of fire retardants of aluminium hydroxide and is used, two kinds of fire retardants are also used the generation synergistic effect, can not only make rubber item have good flame-retardant effect, also have thermally-stabilised good, efficient, press down cigarette, safety, pollution-free substantially to environment is dripped, is filled in resistance;
3. vulcanization system is taken into account the singularity of versatility and glue kind, characteristics according to chloroprene rubber and two kinds of rubbers of natural gum, neoprene latex is adopted metal oxide vulcanization, natural gum adopts traditional sulfur sulfide system, when plateau cure, how sulfur-crosslinked crosslinking structure mainly be, have only few single sulphur or two sulphur structure, it is fast to have vulcanization rate, make the flexible resistance of rubber item good, comprehensive physical is excellent, can improve simultaneously because of adding a large amount of fire retardants and reduce the shortcoming of physical and mechanical properties;
4. select for use the moderate semi-reinforcing hydrocarbon black of suitable consumption, particle diameter as strengthening agent, improve the influence that physical and mechanical properties that fire retardant makes sizing material descends.
The present invention is because adopt chloroprene rubber and two kinds of rubbers of natural gum and usefulness, adopt the vulcanization system of metal oxide and Sulfur and usefulness, adopt antimonous oxide and two kinds of fire retardants of aluminium hydroxide and usefulness, adopt suitable consumption, the moderate semi-reinforcing hydrocarbon black of particle diameter is as strengthening agent, the rubber item of making not only has intensity preferably, elasticity, hardness, rebound resilience, flexibility and physical and chemical performance such as anti-aging, also have flame retardant resistance and smoke elimination, oxygen index is higher, smoke index is lower, be suitable for being produced on the laying public place, passenger train, subway, during floors such as bus, the caoutchouc elasticity between floor frame and the floor supports goods.
Below in conjunction with embodiment, the present invention is further described.
