Description
Technical field
The present invention relates to the preparation method of a kind of fire retardant, be specifically related to the environmentally friendly preparation side of a kind of chlorinated paraffin
Method.
Background technology
Chlorinated paraffin has that volatility is low, fire-retardant, electrical insulating property is good and many excellent physicochemical properties such as resistance to chemical attack,
Can be used as fire retardant polrvinyl chloride secondary plasticizer(-iser) etc., be widely used in produce plastics, cable, plate, flexible pipe, artificial leather and
Rubbers etc. are it can also be used to the additive of paint, coating and lubricating oil etc..Due to important in commercial Application of chlorinated paraffin
Property, the therefore optimization of its production method, arouse widespread concern.
At present, the mode of production of chlorinated paraffin mainly has thermal chlorination and photocatalytic method.
The thermal chlorination response time is long, and the response time such as chlorinated paraffin-52 is typically for up to about 60h, causes production efficiency
The phenomenon such as low, energy consumption is high and chlorine utilization is low highlights.
Photocatalytic method is to promote chlorine molecule covalent bond fission to be dissociated into chlorine radical with the ultraviolet light of about 340nm, activation
The chlorine radical of state bombards paraffin molecule continuously and forms C-Cl key, accelerates reaction rate, generates the response time of paraffin-52
It is down to 24-36h (and 24-38h.But, the theoretical and practical production experience according to bimodulus, the course of reaction of chlorinated paraffin is homogeneous
Reaction, chlorine is first dissolved in paraffin the most just chemical reaction, and chlorine dissolution velocity in paraffin is less than response speed,
The most whole reaction is mass transport limitation step
In three of the above mode, it is the most extensive that the mode of the third employing light chlorination process is applied, in order to use continuously
Property and producing on a large scale, can use multiple reactor in prior art is used in series, such as Patent No. 200610025410.7
In the Chinese patent of entitled " method of continuous prodution chlorinated paraffin ", just used this mode, then regardless of
In the method for the consecutive production chlorinated paraffin of mode, each reactor all can produce tail gas, and tail gas is chlorine and chlorination
Hydrogen, in existing method, is directly to be collected by the tail gas produced in each reactor, enters in exhaust treatment system,
This mode, becomes huge by the supply making chlorine, the most well utilizes for chlorine present in tail gas, increases
Add production cost.
Summary of the invention
It is an object of the invention to, it is provided that the preparation method of a kind of chlorinated paraffin, technique is simple, and the response time is short, chlorine
Consuming few, conversion ratio is high, reduces production cost.
Technical scheme is as follows:
A kind of environmentally friendly preparation method of chlorinated paraffin, it comprises the following steps:
(1). liquid paraffin raw material is joined in chlorination reactor, is heated to 30 DEG C-60 DEG C, add liquid paraffin weight
The catalyst of 0.1-10%；
(2). radiate with 40-60W electric filament lamp, in reactor, be slowly introducing chlorine simultaneously, control reaction temperature and exist
In the range of 90 DEG C-100 DEG C, react 90-110min, when reaction mass density reaches about 1.25 grams/cc, stop logical chlorine
Gas；
(3) it is passed through nitrogen, drives the hydrogen chloride and unreacted a small amount of chlorine generated in course of reaction out of, add in material
Weight of material 0.05～the stabilizer of 0.15%, stir, and cools down and i.e. obtains chlorinated paraffin-52.
Stabilizer is heat stabilizer and light stabilizer.
Heat stabilizer be the one in Ethylene glycol diglycidyl ether, HFW 2 complex stabilizer, epoxy soybean oil or
Several.
Light stabilizer is ESCALOL 567.
The preparation method of chlorinated paraffin that the present invention provides, it has the beneficial effects that, technique is simple, and the response time is short, chlorine
Gas consumption is few, and conversion ratio is high, reduces production cost, and liquid paraffin raw material is not required to refine, without spent acid, waste sludge discharge, and green ring
Protect, there is preferable economic benefit and social benefit.
