Abstract
The invention relates to a method for ultrasonically controlling a terephthalic acid aluminum whisker. According to the method, terephthalic acid is dissolved in a sodium hydroxide solution, soluble aluminum salt is added to a clarified liquid, reaction is performed for 6-30 min under the action of ultrasonic waves, and final sediment is filtered and dried at 150 DEG C. The production method has short production time, prepared terephthalic acid aluminum can have a special whisker structure through ultrasonic control, and the mechanical properties of materials such as PVC (polyvinyl chloride) and the like can be improved greatly while the thermal stability is kept.
Description
Technical field
The present invention relates to a kind of method of ultrasonic controlled p-phthalic acid al whisker.
Background technology
Whisker refers to a kind of fiber growing under manual control condition with high-purity single crystal form, therefore has excellent
Mechanical property.Due to its courtyard structural arrangement high-sequential, structural integrity is difficult to accommodate the defect living forever in big crystal, so
Mechanical strength is approximately equal to the theoretical strength of valence link power between atom, is very excellent advanced composite material (ACM) strengthening and toughening material.
The Chinese invention patent of Application No. 201310140733.0 indicates that a kind of p-phthalic acid aluminum pvc is thermally-stabilised
Agent and preparation method thereof.Preparation-obtained heat stabilizer stabilization time is long, asepsis environment-protecting, and the transparency of product is high.
But its response time is relatively long, needs 1～24h could prepare and complete.
Technology contents
It is an object of the present invention to obtaining a kind of method of ultrasonic controlled p-phthalic acid whisker, with faster and better production
P-phthalic acid aluminum pvc heat stabilizer.
The invention provides a kind of method of ultrasonic controlled p-phthalic acid al whisker, comprise the steps:
By p-phthalic acid with sodium hydroxide solution dissolve, toward clear liquor in add aluminum soluble salt, concentration for 1mol/l～
30mol/l, after react 1～10min under the high-frequency ultrasonic of 1000khz, then change low frequency ultrasound so that solution is in 200khz
Ultrasound wave under react 5～20min, final precipitate is filtered, and in 150 DEG C of drying present invention.
The technique effect of the present invention: the method production time is short, and by ultrasonic control so that prepare to benzene two
Aluminium triformate possesses special whisker structure, while keeps thermally-stabilised performance, can also greatly strengthen the materials such as pvc
Mechanical property.

Specific embodiment and accompanying drawing
Embodiment 1: p-phthalic acid sodium hydroxide solution is dissolved, adds aluminum soluble salt toward in clear liquor, concentration is
1mol/l, after react 1min under the high-frequency ultrasonic of 1000khz, then change low frequency ultrasound so that solution is in 200khz
Ultrasound wave under react 5min, by final precipitate filter, and 150 DEG C dry.
Embodiment 2: p-phthalic acid sodium hydroxide solution is dissolved, adds aluminum soluble salt toward in clear liquor, concentration is
30mol/l, after react 10min under the high-frequency ultrasonic of 1000khz, then change low frequency ultrasound so that solution is in 200khz
Ultrasound wave under react 20min, by final precipitate filter, and 150 DEG C dry.
Embodiment 3: p-phthalic acid sodium hydroxide solution is dissolved, adds aluminum soluble salt toward in clear liquor, concentration is
15mol/l, after react 5min under the high-frequency ultrasonic of 1000khz, then change low frequency ultrasound so that solution is in 200khz
Ultrasound wave under react 10min, by final precipitate filter, and 150 DEG C dry.
Embodiment 4: p-phthalic acid sodium hydroxide solution is dissolved, adds aluminum soluble salt toward in clear liquor, concentration is
1mol/l, reacts 1h, and final precipitate is filtered, and dries at 150 DEG C.
Embodiment 5: by the material of embodiment 1-3 gained (experiment 1-4), traditional heat stabilizer organotin (experiment 5) with
Pvc is blended, and makes plastic tab, carries out coherent detection.The national standard of each measured performance parameter method institute foundation is concrete
As follows: tensile strength is pressed gb/t 1701-2001 and measured, elongation at break is pressed gb/t 1701-2001 and is measured, when thermally-stabilised
Between test be to carry out static thermal ageing test in the baking oven that thin slice is put into 180 ± 1 DEG C, will be fixed for time that stain in thin slice
For the time that heat is steady.Detection data such as table 1 below:
Table 1
As can be seen from the table, the p-phthalic acid aluminothermy stabilizer heat-stable time of gained of the present invention is long, and can effectively increase
The mechanical property of strong pvc material, and preparation time is short.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff completely may be used
, in the range of without departing from this invention technological thought, to carry out various change and modification.The technical model of this invention
Enclose the content being not limited in description it is necessary to determine its technical scope according to right.
