Abstract
The present invention relates to the technical field of rubber chemicals, and particularly relates to a natural rubber latex preservative. The rubber latex preservative comprises the following raw materials in parts by weight: 0.2-0.5 part of sodium metabisulfite, 0.1-0.5 part of butyl p-hydroxybenzoate, 4-10 parts of sodium bicarbonate, 1-5 parts of sodium benzoate and 1-3 parts of citric acid. Object of the present invention is to provide a safe, environmentally-friendly, low-price, easy-to-use natural rubber latex preservative.
Description
Technical field
The present invention relates to the technical field of rubber chemicals, specifically a kind of natural rubber breast antistaling agent.
Background technology
Rubber is a kind of important raw material of industry, is known as the four big raw materials of industry with iron and steel, oil, coal.Rubber is owing to having distinctive high resiliency and good physical and mechanical properties and electrical insulation capability, and purposes is extremely wide.Therefore the consumption of rubber is very big.Conventionally used rubber includes natural rubber and synthetic rubber.Current global demand year reaches 20,000,000 tons, wherein asynthetic rubber 12,000,000 tons, natural rubber 8,000,000 tons.But asynthetic rubber cannot replace natural rubber.The 7% of the natural rubber yield Zhi Zhan world of China, and demand accounts for more than the 22% of the world.Natural rubber is from containing the rubber extracted glue plant.The latex collected from rubber tree is a kind of milky white liquid, and its outward appearance is similar to milk；It is the biosynthetic product of rubber tree, and its composition is sufficiently complex, except containing except rubber hydrocarbon and water, possibly together with other a small amount of materials.Generally other materials of the nonrubber in latex are divided into protein, class ester thing, the molten thing of acetone, water-soluble salt and inorganic salt, enzyme and antibacterial etc..In the world today natural latex rubber fresh-keeping all with ammonia, ammonia is toxic, contaminated environment not only, and make latex rubber quality decline, dry content reduces, and is unfavorable for industrialized production.
Summary of the invention
It is an object of the invention to provide a kind of safety and environmental protection, natural rubber breast antistaling agent cheap, easy to use.
The technical solution used in the present invention is, a kind of natural rubber breast antistaling agent, is made up of by weight following raw material: sodium pyrosulfite 0.2-0.5 part, butyl p-hydroxybenzoate 0.1-0.5 part, sodium bicarbonate 4-10 part, sodium benzoate 1-5 part, citric acid 1-3 part.
The method have the advantages that not only nonhazardous, but also free from environmental pollution, and improve quality and the dry content of natural rubber breast, easy to use, cost reduces.
Detailed description of the invention
The present invention is further described with the following Examples.
Embodiment 1, a kind of natural rubber breast antistaling agent, it is made up of by weight following raw material: sodium pyrosulfite 0.5 part, butyl p-hydroxybenzoate 0.5 part, sodium bicarbonate 10 parts, sodium benzoate 5 parts, citric acid 3 parts.
Embodiment 2, a kind of natural rubber breast antistaling agent, it is made up of by weight following raw material: sodium pyrosulfite 0.2 part, butyl p-hydroxybenzoate 0.1 part, sodium bicarbonate 4 parts, sodium benzoate 1 part, citric acid 1 part.
Embodiment 3, a kind of natural rubber breast antistaling agent, it is made up of by weight following raw material: sodium pyrosulfite 0.4 part, butyl p-hydroxybenzoate 0.3 part, sodium bicarbonate 7 parts, sodium benzoate 3 parts, citric acid 2 parts.
Should be understood that this embodiment is merely to illustrate the present invention rather than restriction the scope of the present invention.Furthermore, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims protection defined equally.
