(5) by aerated bricks green body be put into autoclave carry out high pressure-temperature it is steam-cured, finally out kettle up to high-strength environment-friendly
Aerated bricks.
Experiment 1
The pressure resistance of high-strength environment-friendly aerated bricks is detected according to GB/T4111-2013 " concrete segment and brick test method "
It spends (MPa).
Experiment 2
Aerated bricks made from embodiment 1-6 and comparative example 1-3 are placed under ultraviolet light and are irradiated for 24 hours, aerated bricks, root are further taken out
According to the resistance to compression after GB/T4111-2013 " concrete segment and brick test method " detection high-strength environment-friendly aerated bricks ultraviolet light irradiation
Intensity (MPa).
The detection data of each embodiment is shown in Table 1, and the detection data of each comparative example is shown in Table 2.
Table 1
Table 2
It can be obtained according to the data comparison of comparative example 1 in table 2 and comparative example 2, the group in the component ratio comparative example 1 of comparative example 2
Divide and increased m-hydroxybenzoic acid newly, the compression strength after compression strength and the ultraviolet light irradiation of comparative example 2 is above comparative example 1
, but reinforcing effect is unobvious, illustrates to be individually added into m-hydroxybenzoic acid, may occur between different m-hydroxybenzoic acids anti-
It answers, so that being crosslinked between molecule to form reticular structure mutually, to be conducive to enhance the resistance to compression of aerated bricks to a certain extent
Intensity；Since the conjugated structure of phenyl ring has the function of certain absorption to ultraviolet light, to be conducive to enhance the anti-of aerated bricks
Imparted energy, so that the compression strength enhancing after the ultraviolet light irradiation of aerated bricks.
It can be obtained according to the data comparison of comparative example 1 in table 2 and comparative example 3, in the component ratio comparative example 1 in comparative example 3
Component has increased Nipasol newly, but the data of comparative example 3 are close with the data of comparative example 1, illustrates by being individually added into oxybenzene third
Ester influences less the compression strength of aerated bricks and anti-ultraviolet property.
It can be obtained according to the data comparison of embodiment 1-3 in table 1 and comparative example 1-3 in table 2, between embodiment 1-3 both joined
Hydroxybenzoic acid, and joined Nipasol, m-hydroxybenzoic acid is not only added in comparative example 1, but also that Nipasol is not added, than
M-hydroxybenzoic acid has been individually added into compared with example 2, comparative example 3 has been individually added into Nipasol, but comparative example 2 and comparative example 3
Data are little with the difference of the data of comparative example 1, illustrate to be individually added into m-hydroxybenzoic acid or are individually added into Nipasol pair
The compression strength of aerated bricks and the influence of anti-ultraviolet property are unobvious, but m-hydroxybenzoic acid and oxybenzene are added simultaneously
Propyl ester, the compression strength and anti-ultraviolet property of aerated bricks are substantially improved, and illustrate that m-hydroxybenzoic acid is easy and oxybenzene third
Reaction is easy to happen between ester, so that it is entangled to each other to form reticular structure between molecule, meanwhile, the phenyl ring on strand is in rigid
Property, it is not easy to it rotates, it is not easy to fold, to be conducive to enhance the compression strength of aerated bricks；Meanwhile the conjugation knot of phenyl ring
Structure has certain absorption to ultraviolet light, to be conducive to enhance the anti-ultraviolet property of aerated bricks.
It can be obtained according to the data comparison of embodiment 1-3 in table 1 and embodiment 4-6, the component ratio embodiment in embodiment 4-6
The component of 1-3 has increased aluminium powder, hollow glass micropearl, SILICA FUME, waste and old rubber particle, impregnating with silane agent newly, and embodiment 4-6's is anti-
Compressive Strength and anti-ultraviolet property illustrate to a certain extent higher than embodiment 1-3 by the way that aluminium powder, hollow glass is added
Microballon, SILICA FUME, waste and old rubber particle and impregnating with silane agent, can improve to a certain extent aerated bricks compression strength and
Anti-ultraviolet property.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
