Performance test:
To prove technical effect of the invention, respectively to the flame retardant property of the timber of impregnation in embodiment 1-3, anti-
Corrosive nature and wear-resisting property are tested, and specific test method and result are as follows:
One, flame retardant property is tested:
(1) measurement of timber oxygen index (OI)
The timber of impregnation in embodiment 1-3 is processed into 100mm × 100mm × 10mm size test specimen respectively,
Then it with referring to GB/T2406-2009 " one oxygen index method of Plastics Combustion performance test method ", is measured respectively with oxygen index instrument each
The oxygen index (OI) of test specimen.
Measurement result shows that the oxygen index value of the timber in embodiment 1-3 is respectively 34.6,38.4 and 47.1.According to biography
The division of the combustion of wood rank of system, oxygen index (OI) reaches 27, and the above are incombustible materials.As it can be seen that being handled by flame-retardant impregnating of the present invention
The timber crossed has reached the standard of incombustible material, has preferable flame retardant effect.
(2) burning time measures
According to GB T 16172-2007 " construction material heat release rate test method ", will be impregnated in embodiment 1-3 respectively
It processed timber and is not impregnated with processed China fir, pine and rubber wood timber and is processed into 100mm × 100mm × 10mm size
Test specimen is to be not impregnated with processed China fir, pine and rubber wood timber test specimen using the timber test specimen in embodiment 1-3 as experimental group
Control group carries out burning time measurement, when measurement, by each group timber test specimen with electric arc under the conditions of radiant power is 50KW/m2 into
Row lights test, and records the burning time of each timber test specimen respectively；
Burning velocity measurement result shows that the burning time of the timber test specimen of impregnation in embodiment 1 is 230s, right
It is 50s according to a group burning time for China fir test specimen；The burning time of the timber test specimen of impregnation in embodiment 2 is 212s, right
It is 35s according to a group burning time for pine test specimen；The burning time of the timber test specimen of impregnation in embodiment 3 is 247s, right
It is 65s according to a group burning time for rubber wood timber test specimen；In general burning time is bigger, and material is more not easy to light, fire risk
It is smaller, it is seen then that be not easy to be ignited by the processed timber of flame-retardant impregnating of the present invention, fire risk is smaller, particularly suitable
In indoor furniture and interior decoration field.
Two, Corrosion Protection is tested
