Abstract
The present invention relates to polymeric material field, the synthesis of more specifically to a kind of hyperbranched epoxy resin and its application in asphalt water-proof coiled material.A kind of hyperbranched epoxy resin has been synthesized first with trihydroxymethylpropanyltri diglycidyl ether and dicarboxylic acids, has been then applied in asphaltic base waterproof roll, the adhesive property of asphaltic base waterproof roll can be effectively improved.
Description
Technical field
The present invention relates to polymeric material field, the synthesis of more specifically to a kind of hyperbranched epoxy resin and its
Application in asphalt water-proof coiled material.
Background technique
Asphaltic base waterproof roll is divided into hot melt, self-adhesion according to form of construction work and is mechanically fixed three classes at present.Heat class pitch
Base waterproof roll is widely used, and construction method is mature, is firmly bonded reliably, but need to heat in work progress, is also easy to produce flue gas,
Pollute environment；And it once falls off and cannot be bonded again with base.Being mechanically fixed class asphalt water-proof coiled material cannot form completely with base
It is viscous, once it leaks, it is difficult to it is safeguarded.Self-adhesive asphalt waterproof coiled material takes the form of construction work of cold bonding knot, securely and reliably, can
It is formed with base completely viscous.But it over time, can decline with the peel strength of base, and then occur being detached from showing for base
As.
Therefore, a kind of tackifying resin can be added in asphaltic base waterproof roll, for improving asphalt water-proof coiled material and base
Peel strength.
Dissaving polymer has that 3 D stereo reticular structure, active site is more, viscosity is small, good etc. special with matrix amalgamation
Point, has broad application prospects, at present photoelectric material, coating, adhesive, nanosecond science and technology, drug carrier, etc. fields all tables
Huge application value is revealed.
Summary of the invention
In order to solve the problems, such as that asphalt water-proof coiled material adhesive property is insufficient, the present invention provides a kind of hyperbranched asphalt mixtures modified by epoxy resin
Rouge, for solving the above problems.
The present invention also provides the preparation methods of the hyperbranched epoxy resin.
The hyperbranched epoxy resin through the following steps that realize.
Trihydroxymethylpropanyltri diglycidyl ether is added in the four-hole boiling flask with blender condenser pipe, adds two
First carboxylic acid and catalyst, are warming up to 120 DEG C, reaction 5h both the hyperbranched epoxy resin.
The dicarboxylic acids be one of ethanedioic acid, adipic acid, decanedioic acid, phthalic acid, terephthalic acid (TPA) or
It is two or more.
The catalyst be triethylamine, N, Louis' bases such as N- dimethyl benzylamine, triphenyl phosphorus, tributyl phosphorus, or
Throughout trimethyl ammonium chloride, tetramethyl ammonium chloride, etamon chloride, tetramethyl amine bromide, tetraethylammonium bromide, tetrabutyl bromine
Change one or more of quaternary ammonium salts such as ammonium.
The catalyst amount is the 0.1wt%-2wt% of reactant gross mass.
The hyperbranched epoxy resin may but be not limited only to the structure that is shown below:
Referring now to the prior art, hyperbranched epoxy resin of the present invention is had the following advantages that.
The preparation method of hyperbranched epoxy resin of the present invention is simple, and raw material is easy to get.To asphaltic base waterproof roll and base
The peel strength of layer has larger improvement, uniform with asphalt water-proof coiled material blending and stirring, does not increase additional technique, is conducive to control
Production cost processed.

Resin.
Performance test
In order to illustrate actual effect of the invention, here is that the hyperbranched epoxy resin that will be prepared in the embodiment of the present invention is added to
In self-adhesive asphalt waterproof coiled material, peel strength performance detection is carried out, examination criteria is according to specified in GB/T 328.20-2007
Method carries out, and testing result is as follows.
Table 1: asphalt water-proof coiled material peel strength
In upper table, comparison is embodied as not adding peel strength when hyperbranched epoxy resin, embodiment 1, embodiment 2, embodiment 3
For add 5wt% hyperbranched epoxy resin when peel strength.There is table it is found that addition hyperbranched epoxy resin can be preferable
Improve the peel strength of asphalt water-proof coiled material and base.
Above-described embodiment is better embodiment of the invention, but embodiments of the present invention are not by the limit of embodiment
System, other any changes made without departing from the spirit and principles of the present invention, modification, combination, substitution, simplification should all regard
For equivalence replacement mode, it is included within the scope of the present invention.
