Good, impact resistance is good, resistance to ag(e)ing and water-tolerant, can scratch at room temperature or spraying application, is suitble to promote the use of.
Compared with Examples 1 to 7, without adding surfactant in comparative example 1, the uncured rubber-asphalt waterproof of preparation is applied
Expect that adhesion strength and peel strength are weaker, illustrates if surfactant is not added, each component and asphalt in water-repellent paint
Between poor compatibility, the caking property so as to cause uncured rubber asphalt waterproof coating is bad, and peel strength is poor, easily be layered,
Practical effect is bad.
Compared with Examples 1 to 7, there is no 3- (2,3 the third oxygen of epoxy) hydroxypropyl methyl diethoxy silane in comparative example 2, receives
Rice kaolin, the uncured rubber asphalt waterproof coating heat-resisting quantity and poor impact resistance of preparation, illustrate formula in be added 3- (2,
3 the third oxygen of epoxy) hydroxypropyl methyl diethoxy silane and nano kaoline, so that the uncured rubber asphalt waterproof coating tool of preparation
Standby two kinds of properties of organic-inorganic, significantly improve the heat-resisting quantity of water-repellent paint, while improving the impact resistance of water-repellent paint.
Compared with Examples 1 to 7, without adding sorbierite and polyethyleneimine, the uncured rubber drip of preparation in comparative example 3
Green water-repellent paint low temperature flexibility is poor, adhesion strength and peel strength are poor, illustrates sorbierite and polyethyleneimine mating reaction, can
Significantly improve low temperature flexibility, adhesion strength and the peel strength of uncured rubber asphalt waterproof coating.
From Examples 1 to 7 with the comparison of comparative example 1~3 as can be seen that each component mutually cooperates in formula of the invention
Effect, so that the high and low temperature resistance of the uncured rubber asphalt waterproof coating of preparation is good, caking property is good, impact resistance is good, with
The peel strength of substrate is high, small with the peel strength variation of substrate after heat treatment and immersion processing, illustrates resistance to ag(e)ing and water-fast
Property is good, lacks wherein any one component, can all have an impact to the performance of uncured rubber asphalt waterproof coating.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
