Abstract
The invention relates to the formula of environment-friendly flame-retardant chloroprene rubber. The flame-retardant chloroprene rubber, according to the formula thereof, comprises the following components by weight part: 100 parts of chloroprene rubber, 1 to 4 parts of hexamethyl-quinoxaline-2,3-dithioformate, 1 to 2 parts of DM as accelerator, 3 to 10 parts of zinc oxide, 3 to 10 parts of magnesium oxide, 1 to 2 parts of 4010NA as anti-ager, 0.5 to 2 parts of paraffin, 20 to 40 parts of FEF (fast-extruding furnace) carbon black (N550), 30 to 40 parts of kaolin, 30 to 50 parts of aluminum hydroxide, 5 to 15 parts of zinc borate, 10 to 20 parts of FR-808A and 5 to 15 parts of tricresyl phosphate. According to the comparative analysis on the performance of the chloroprene formula using halogen-containing flame retardant and the chloroprene rubber formula using halogen-free flame retardant, the performance of the formula using the halogen-free flame retardant in the invention can fully satisfy the requirements of standards, thus substituting for the chloroprene formula using the halogen-containing flame retardant; and based on the chloroprene rubber formula, the invention can meet the requirements of the flame-retardant application, and the materials of the formula are environment friendly and safe for human bodies.
Description
Technical field
The present invention relates to the rubber compounding technical field, particularly a kind of chloroprene rubber prescription of environmental protection flame retardant.
Background technology
Along with the enhancing of environmental consciousness, more and more higher to the safety and environmental protection requirement of use elastomeric material.Domestic common chloroprene rubber flame-retardant formulations is to use halogen containing flame-retardants such as brominated flame-retardant, chlorine-based flame retardant more at present, though use this based flame retardant can satisfy flame retardant effect preferably, in case yet the presence of fire meeting produces a large amount of deleterious corrosive hydrogen halides gases, cause secondary harm, its harm is more serious than the consequence that burning causes usually, serious harm people's life security.
Summary of the invention
Purpose of the present invention mainly is the fire retardant poisonous and harmful problem that solves in the present flame-retardant chloroprene rubber prescription, proposes to adopt the bittern-free flame-proof material exploitation flame-retardant chloroprene rubber prescription of nontoxic, low cigarette, and guarantees flame retardant effect and other performance requriements of sizing material.Reach test practice in a large number by the data of searching and determine the aluminium hydroxide of use inorganic combustion inhibitor: it makes time spent generation water, and the heat around can absorbing in the vaporescence of water after being heated.The aluminium hydroxide of two molecules can disengage the water of 3 molecules, and its quality is equivalent to 36.4% of aluminium hydroxide.Have the partition oxygen source, suppress the fire spreading effect.Though aluminium hydroxide has wide development prospect, its shortcoming awaits overcoming: must fill the ability display effect in a large number, single time spent should be no less than 60 parts, and surpassing 120 parts just can have comparatively ideal effect.Owing to need a large amount of fillings to cause properties of rubber to descend, therefore must use other fire retardant and not influence flame retardant effect again with reducing its filling consumption.Find zinc borate and aluminium hydroxide and good by test with the back flame retardant effect.Because zinc borate and aluminium hydroxide and usefulness, in burning, generate porous hard agglomerate, can further stop the rubber thermolysis, and the contacting of obstruct air and flame.
The environmental protection fire retarding agent FR-808A that another novel phosphorus-containing is nitrogenous also uses back cooperative flame retardant better effects if with above two kinds of fire retardants, and reduces the consumption of each fire retardant.
Phosphonium flame retardant has the plasticising function concurrently based on phosphoric acid lipid.
Its chloride (40%) just has self-extinguishing with regard to chloroprene rubber, but adding inorganic filler potter's clay and lime carbonate can improve flame retardant resistance.
The ratio of quality and the number of copies of described flame-retardant chloroprene rubber recipe ingredient is:
| Sequence number | Component | Mass fraction (gram) |
| 1 | Chloroprene rubber | 100 |
| 2 | Hexamethyl quinoxaline-2, the 3-dithio formate | 1～4 |
| 3 | Altax | 1～2 |
| 4 | Zinc oxide | 3～10 |
| 5 | Magnesium oxide | 3～10 |
| 6 | Antioxidant 4010NA | 1～2 |
| 7 | Paraffin | 0.5～2 |
| 8 | The fast carbon black N550 that extrudes | 20～40 |
| 9 | Kaolin | 30～40 |
| 10 | Aluminium hydroxide | 30～50 |
| 11 | Zinc borate | 5～15 |
| 12 | FR-808A | 10～20 |
| 13 | Trimethylbenzene lipoprotein of phosphoric acid | 5～15 |
Embodiment
Flame-retardant chloroprene rubber prescription embodiment:
In mass fraction
Carry out mixing processing by starting material and consumption in the listed prescription: rubber, starting material weighing-section banburying-a section are opened refining-following sheet-two section banburying-two and section are opened refining-following sheet-sulfide film-cut style-test detection by standard.
Be to using halogen containing flame-retardant neoprene prescription and the performance comparison of using halogen-free flame retardants chloroprene rubber prescription below:
By the performance comparison analysis to using halogen containing flame-retardant neoprene prescription and use halogen-free flame retardants chloroprene rubber to fill a prescription, its halogen-free flame retardants performance formula satisfies standard-required fully, can substitute halogen containing flame-retardant neoprene prescription.Use this chloroprene rubber prescription promptly can satisfy fire-retardant service requirements, and the materials used environmental protection is to human body safety.
The flame-retardant chloroprene rubber prescription that the present invention proposes, describe in detail by above, person skilled obviously can be in not breaking away from content of the present invention, spirit and scope to prescription as herein described and the preparation method changes or suitably change realize the technology of the present invention with combination.Special needs to be pointed out is, the replacement that all are similar and change apparent to those skilled in the artly, they are regarded as being included in spirit of the present invention, scope and the content.
