Abstract
The invention discloses a root resistant agent for production of a root resistant material and a preparation method of the root resistant agent. The root resistant agent is prepared from dimethyl tetrachlorophenoxypropionic acid, polyethylene glycol, polyoxyethylene lauryl ether, polydimethylsiloxane, nonylphenol polyoxyethylene ether, ethyl alcohol and 4-chlorophenoxyacetic acid. According to the preparation method, dimethyl tetrachlorophenoxypropionic acid, 4-chlorophenoxyacetic acid and absolute ethyl alcohol are mixed, added to a reaction kettle and subjected to reflux under catalysis of p-Toluenesulfonic acid; then polyethylene glycol, polyoxyethylene lauryl ether, polydimethylsiloxane, nonylphenol polyoxyethylene ether and ethyl alcohol are added, stirred sufficiently and left to stand for reaction; a product after the reaction is taken out and cooled naturally. The root resistant agent has the functions that when a plant root system is contacted with a waterproof material containing the root resistant agent in a growth process, the plant root system is inhibited and expelled, so that the plant root system is prevented from growing downwards continuously, accordingly, the penetrating damage of the plant root system to a waterproof layer is reduced, the completeness of the waterproof layer is guaranteed, and the service life of the waterproof layer is prolonged greatly.
Description
Technical field
The present invention relates to, specifically a kind of root resistance agent for the production of root resistance material and preparation method thereof.
Background technology
In recent years, along with country is to the great attention of building energy conservation, planted roof system obtains promotion and application widely.And the useful life of planted roof system is somewhat dependent upon the root-resistant puncturing performance of root-resistant puncturing water-proof material.
Root-resistant puncturing water-proof material comprises physics root resistance water-proof material and chemical root resistance water-proof material.Physics root resistance water-proof material is the puncture that compactness itself that had by root-resistant puncturing water-proof material and high strength, highly corrosive resist root system of plant.Chemistry root resistance water-proof material is that a certain amount of chemical root resistance agent of admixture penetrates water-proof material to stop root system of plant in common waterproof roll, does not affect plant normal growth again simultaneously.
Existing root resistance agent is in the market all introduce from external import, expensive, substantially increases root resistance material cost, to such an extent as to is unfavorable for the popularization of domestic root resistance material.
Summary of the invention
The object of the present invention is to provide a kind of root resistance agent for the production of root resistance material and preparation method thereof, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of root resistance agent for the production of root resistance material, be prepared from by the raw material of following massfraction: dimethyl tetrachloro phenoxy propionic acid 30 ~ 30.5%, polyoxyethylene glycol 24 ~ 24.5%, ethoxylated dodecyl alcohol 5 ~ 5.5%, polydimethylsiloxane 0.5 ~ 1%, polyoxyethylene nonylphenol ether 0.2 ~ 0.5%, ethanol 1 ~ 1.5%, p-chlorophenoxyacetic acid 37.6 ~ 37.9%.
A preparation method for the described root resistance agent for the production of root resistance material, concrete preparation process is as follows:
(1) dimethyl tetrachloro phenoxy propionic acid, p-chlorophenoxyacetic acid and dehydrated alcohol being carried out mixing adds in reactor, reflux 1.8 ~ 2.2h under the catalysis of p-methyl benzenesulfonic acid, prepares the mixture of dimethyl tetrachlorobenzene oxygen ethyl propionate and ethyl p-chlorophenoxyacetatecatalyzed;
(2) add polyoxyethylene glycol, ethoxylated dodecyl alcohol, polydimethylsiloxane, polyoxyethylene nonylphenol ether and ethanol in the mixture in aforesaid reaction vessel, fully stir, staticize reaction 1.5 ~ 2.5h, after reaction terminates, take out naturally cooling.
Compared with prior art, the invention has the beneficial effects as follows: effect of the present invention is that the root system of plant runs into the water-proof material containing this product in growth overshoot, will be suppressed and drive root system of plant, make it can not continue downward growth, thus reduce root system of plant to the outbreak-crash of waterproof layer, ensure that the integrity of waterproof layer, substantially prolongs the work-ing life of waterproof layer.
