Description
Technical field
The present invention relates to a kind of method for preparing rubber plastizing agent, particularly relate to a kind of method that waste cooking oil prepares rubber plastizing agent.
Background technology
Epoxy plasticiser mainly comprises Epoxy oil and the large class of epoxy aliphatic ester two, and epoxy aliphatic ester also has more excellent oilness, consistency and dispersiveness except the advantage with Epoxy oil.Can contain high unsaturated fatty acid by epoxidised vegetables oil, as soybean oil, linseed oil, rapeseed oil, sweet oil, Semen Maydis oil, safflower wet goods, in addition, some other animal grease also can be applied in epoxidation reaction, as lard, fish oil etc. more.Wherein most important modal be exactly epoxidised soybean oil, it has good thermotolerance, photostabilization and low temperature flexibility, and volatility is low, there is no toxicity, is one of green plasticization agent of being most widely used of China.
Along with the raising day by day that rubber industry requires the softening agent feature of environmental protection, exploitation bio-based environment-friendly type softening agent has become the hot subject of current Rubber Chemicals Industries research.The people's of the Northeast edible oil be take soybean oil as main.Soybean oil, as the high yield vegetables oil, occupies critical role with the good feature of environmental protection and resource class reproducibility at novel material and new energy field, and its effective utilization is more and more paid attention to.
The composition of waste cooking oil is mainly soybean oil and animal tallow oil, and, through high temperature repeatedly, is easier to it and autohemagglutination occurs in sulfidation and react with vulcanizing agent.So by waste oil softening agent as rubber industry after epoxidation is processed for food and drink.Not only can solve the random exhaust emission environmental problem of waste cooking oil, can also effectively solve the problem such as healthy that the oily backflow dining table of waste oil endangers us.
Summary of the invention
The object of the present invention is to provide a kind of waste cooking oil to prepare the method for rubber plastizing agent, the present invention adds the waste oil after epoxidation in rubber to, the paired sizing material of waste cooking oil autohemagglutination has the low-molecular(weight)polymer of obvious plastification, be grafted on the sizing material molecular chain, reach good plasticization effect, play the effect that improves material mechanical performance and plasticising.
The objective of the invention is to be achieved through the following technical solutions:
Waste cooking oil prepares the method for rubber plastizing agent, and described method comprises that preparation process is as follows:
A. selecting softening agent is the waste cooking oil that epoxidation is processed, and the oxirane value scope of epoxidation waste cooking oil is 4.58 ~ 4.96;
B. in plasto rubber processing, batch mixing according to the following ratio: saturated rubber/unsaturated rubber and and with 100 parts, zinc oxide 3-5 part, stearic acid 2-4 part, anti-aging agent 1-4 part, paraffin wax 1-1.5, carbon black 50-40 part, softening agent 0-8 part, promotor 1-1.5 part, Sulfur 1-3 part, other auxiliary agents are as scorch retarder etc.
Described waste cooking oil prepares the method for rubber plastizing agent, and described saturated rubber is highly saturated nitrile rubber, ethylene propylene rubber, chlorinatedpolyethylene, chlorosulfonated polyethylene, acrylic elastomer, viton.
Described waste cooking oil prepares the method for rubber plastizing agent, and described unsaturated rubber is natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, polyisoprene rubber, terpolymer EP rubber, chloroprene rubber, paracril.
Described waste cooking oil prepares the method for rubber plastizing agent, and described anti-aging agent is phenols, amine, Phosphorus, Sulfur class.
Described waste cooking oil prepares the method for rubber plastizing agent, and described promotor is amine or thiuram type accelerator.
Described waste cooking oil prepares the method for rubber plastizing agent, and described carbon black is general carbon black.
Advantage of the present invention and effect are:
Softening agent preferably has polarity and nonpolar two parts, and polar portion often consists of polar group, and nonpolar part is the alkyl with certain-length.Known according to trench oil component and infrared spectrogram, both contained polar group (as ester group, epoxy group(ing) etc.) in waste cooking oil, contain again nonpolar part, be a kind of softening agent preferably.When rubber vulcanization, the paired sizing material of waste cooking oil autohemagglutination has the low-molecular(weight)polymer of obvious plastification, is grafted on the sizing material molecular chain, reaches good plasticization effect.Its plasticizing mechanism meets reactive plasticizing mechanism.With epoxidation waste cooking oil plasto rubber material, its lower hardness, before 6 parts, tensile strength increases, and tensile yield is increased, and the abrasion volume is minimized, and hardness, by 66 A, is reduced to 60 A.Tensile strength, by 19.41 MPa, is increased to 21.90 MPa, has increased by 2.49 MPa, and elongation at break, by 313 %, is increased to 387 %, and the 72 hours tensile strength after aging, by 11.04MPa, is reduced to 8.88 MPa.72 hours tensile yield after aging, by 197%, are increased to 203%.Constant load compression heat generation temperature, by 15.7 ℃, is reduced to 13.6 ℃.The abrasion volume is by 0.287 cm
3/ 1.61 Km, be reduced to 0.263 cm
3/ 1.61 Km, improved the property indices of rubber.Therefore, having stronger promotion and application is worth.
Embodiment
