Problems solved by technology

But there are also some disadvantages: because of the large amount of smoke produced during combustion, when a fire breaks out, the casualties caused by the large amount of toxic gas produced are more serious than the casualties caused by the fire itself.
[0004] At the same time, excessive use of flame retardants to improve the flame retardancy of rubber will also affect the physical properties of rubber such as elasticity, durability, wear resistance, and pollution resistance.
Although it is described in Korean Patent Application No. 1998-0063646 and No. 1998-0007141 that it contains rubber components and Al(OH) 3 , antimony trioxide and phosphorus-based plasticizers and other non-toxic flame-retardant rubber flooring materials, but this technology has the phenomenon of reducing its physical properties

Embodiment 1、2

[0048]Samples were produced using the ingredients listed in the table below. Specifically, the raw material rubber EPDM is masticated first, and then the remaining additives are sprinkled on the surface of the rubber, and put into a rolling mill for compression, so as to achieve the purpose of compounding the ingredients. Next, the compound is fed into a mold, and a sample is produced by pressing and heating the pressure surface.

[0049] The data in the table below is based on EPDM 100 servings as a standard.

[0052] In order to determine the physical properties of the above samples, the tensile strength of the samples (kgf / cm 2 ), tear strength (kgf / cm), elongation (%), hardness and flame retardancy (m / m10min).

[0053] Tensile strength refers to the strength at which a sample breaks when a load is applied to it, and its measured value is calculated by dividing the breaking load by the initial cross-sectional area.

Abstract

The invention provides a nonpoisonous flame-retardant rubber composition, a preparation method of the composition and a product thereof. Manufacture materials include rubbers 100 parts, hydroxyl-aluminum compounds 150 to 300 parts and antimony oxide compounds 5 to 20 parts; the materials thereof further include trihydroxy methyl propane and tri-methacrylate which are 10 to 30 parts in total; and the parts indicate mass parts. The rubber composition is a nonpoisonous flame-retardant composition. If the nonpoisonous flame-retardant rubber composition is used as floorings and interior decorationmaterials, occurrence of conflagration disaster can be prevented, and casualties caused by smokes and noxious gas can also be avoided.

Description

technical field [0001] The invention belongs to the field of synthetic rubber, and in particular relates to a non-toxic flame-retardant rubber compound, a method for manufacturing the compound and a shaped product thereof. Background technique [0002] Rubber has been widely used in various means of transportation, flooring and interior materials of buildings. However, due to the high flammability of natural rubber and synthetic rubber, once a fire breaks out, people will be helpless. In particular, if a fire breaks out in public transportation such as subways, airplanes, buses, and ships, and public places such as department stores, hospitals, theaters, and schools, it will cause large-scale accidents and easily cause casualties. Recently, due to frequent fires, attention has been paid to the flame retardancy of rubber used for flooring or interior decoration. [0003] In order to improve the flame retardancy of rubber, halogenated flame retardants such as bromine compoun...
