Description
Technical field
The present invention relates to a kind of plastics, more particularly to a kind of modified plastics.
Background technology
Modified plastics belongs to the intermediate products in petrochemical industry chain, mainly by five big general-purpose plastics and
Five large-engineering plastics are processed for plastic matrix, with fire-retardant, anti-impact, high tenacity, workability
The features such as.The development level of the modified plastic industry current overall context of China is relatively low, the life of enterprise inside the circle
Product scale is generally less than normal, and the market situation of product also shows that primary product are more, and intermediate product quality is not
Stably, the characteristics of high-grade products lack, the need for China's 21 century economic development is met.Cause
This, modified plastics is also arranged by country as an important component in new chemical materialses field
One of sciemtifec and technical sphere for emphasis development.
At present, existing general igelite, relative density 1.4 or so, glass transition temperature
77~90 DEG C, 170 DEG C or so start to decompose, and the stability to light and heat is poor, more than 100 DEG C or pass through
Long-time exposure in sunshine, will be decomposed and produce hydrogen chloride, and further autocatalysis is decomposed, and is caused
Discoloration, physical and mechanical properties also declines rapidly.
The content of the invention
(1) technical problem to be solved
The technical problem to be solved in the present invention is to provide one kind and possesses pull resistance, flexing resistance and good stability
Modified plastics.
(2) technical scheme
In order to solve the above technical problems, the present invention provides a kind of modified plastics, including following weight item：
40~50 parts of Corvic, 20~40 parts of acrylic resin, 6~10 parts of aluminium powder, alkali lignin
2~5 parts, 2~4 parts of calcium carbonate, 1~5 part of dispersant, 1~2 part of heat stabilizer, plasticizer 0.5~2
Part.
Further, including following weight item：45 parts of Corvic, acrylic resin 30
Part, 8 parts of aluminium powder, 5 parts of alkali lignin, 4 parts of calcium carbonate, 3 parts of dispersant, 2 parts of heat stabilizer,
1 part of plasticizer.
Further, the aluminium powder is by 200 DEG C of aerobic calcinings.
Further, the heat stabilizer is dibasic lead phosphite.
Further, after the calcium carbonate is soaked 1 hour using 1~2% concentration methacrylic acid solution,
Filtering, is cleaned with deionized water；Then soaked with 1~2% poly- butyl propyleneglycol acid solution again, be heated to
80~90 DEG C, after being kept for 1~2 hour, room temperature is cooled to, filtered, cleaned with deionized water, dried,
It is crushed to 50~100 mesh powder.
Further, the preparation method of the modified plastics is as follows：Material is first weighed, is stirred,
Obtain mixture；Feed the mixture into double screw extruder, processing temperature is 200~260 DEG C of main frames
Rotating speed be 400rpm, after extrusion cool down, air-dry pelletizing, you can prepare the modified plastics.
(3) beneficial effect
Simple production process of the present invention, low cost, performance is good；By using specific process to calcium carbonate
Treatment is modified, the mechanical property of plastics is improve, especially the tensile strength of plastics and bending are strong
Degree；Add through Lv's powder of high-temperature process, improve the heat resistance of plastics.
Specific embodiment
In order to become apparent from understanding present disclosure, it is further described with reference to specific embodiment.
The embodiment of the present invention provides a kind of modified plastics, including following weight item：Corvic
40~50 parts, 20~40 parts of acrylic resin, 6~10 parts of aluminium powder, 2~5 parts of alkali lignin, calcium carbonate
2~4 parts, 1~5 part of dispersant, 1~2 part of heat stabilizer, 0.5~2 part of plasticizer.
As the preferred embodiment of the invention, including following weight item：45 parts of Corvic,
30 parts of acrylic resin, 8 parts of aluminium powder, 5 parts of alkali lignin, 4 parts of calcium carbonate, 3 parts of dispersant,
2 parts of heat stabilizer, 1 part of plasticizer.
Wherein, aluminium powder is by 200 DEG C of aerobic calcinings；Heat stabilizer is dibasic lead phosphite.
After calcium carbonate is soaked 1 hour using 1~2% concentration methacrylic acid solution, deionization is used in filtering
Water is cleaned；Then soaked with 1~2% poly- butyl propyleneglycol acid solution again, be heated to 80~90 DEG C, kept
After 1~2 hour, room temperature is cooled to, filtered, cleaned with deionized water, dry, pulverize to 50~100
Mesh powder.
Corresponding preparation method is as follows：Material is first weighed, is stirred, obtain mixture；Will be mixed
Compound is added in double screw extruder, and processing temperature is that 200~260 DEG C of rotating speeds of main frame are 400rpm,
Cooled down after extrusion, air-dry pelletizing, you can prepare the modified plastics.
The experimental example of the embodiment of the present invention：
The performance test of modified plastics is as shown in table 1：
Table 1
The above is only the preferred embodiment of the present invention, it is noted that for the art
For those of ordinary skill, on the premise of the technology of the present invention principle is not departed from, can also make some
