Problems solved by technology

[0009] In view of the above-mentioned defects and problems that the utilization rate and utilization level of the existing fly ash as a plastic modifier are seriously insufficient, the purpose of the embodiment of the present invention is to provide a high polymer density regulator and its preparation method. The modifier coats the fly ash, and then cross-links the fly ash with a coupling agent to make the fly ash have high lipophilicity and is easy to be compatible with high polymers such as polyvinyl chloride. The resulting high polymers such as plastics , Rubber products have higher stability

Embodiment 1

[0032] Such as figure 1 As shown, the fly ash after vacuum drying is screened by an airflow sieve to obtain coarse fly ash above 200 mesh, and then grind to ultrafine fly ash above 2500 mesh; the screened ultrafine fly ash Burn ash in a crucible at 950-1000°C for 15-20min, then place in a desiccator to cool to room temperature; pour the processed ultra-fine fly ash into a high-speed mixer and stir at high speed, heat to 120°C, and separate Sprinkle slowly or mist spray into the amount of triethanolamine that is 1% of the total amount of fly ash, stir at a high speed for 10 minutes, then add stearic acid with 1.5% of the total amount of fly ash, and cool after stirring at a high speed for 10 minutes; ℃ Use 1% silane coupling agent to cross-link the activated fly ash, mix at high speed for 10 minutes, and finally get a high polymer density regulator for rubber products.

[0033] The airflow sieve is an existing process. In this embodiment, the fourth generation HLQS-160 airflow...

Embodiment 2

[0035] Such as figure 1As shown, the fly ash after vacuum drying is screened by an airflow sieve to obtain medium fly ash with a mesh size of 200 to 500 mesh; the screened medium fly ash is burned in a crucible at 1100~1000°C 15~20min, then put it in a desiccator to cool to room temperature; pour the treated medium fly ash into a high-speed mixer and stir at high speed, heat to 120°C, slowly sprinkle or mist spray the fly ash in batches The total amount of 1% triethylamine, high-speed stirring for 10 minutes; then add 0.5% of the total amount of fly ash dodecylbenzenesulfonic acid, high-speed stirring for 10 minutes to cool; at 90 ° C with 1% titanate coupling The activated fly ash was cross-linked with 0.5% aluminate coupling agent and mixed at high speed for 15 minutes to obtain a high polymer density regulator for asphalt products.

Embodiment 3

[0037] Such as figure 1 As shown, the fly ash after vacuum drying is screened by an airflow sieve to obtain fine coal ash powder with a mesh size of 500 mesh or more; the screened fine fly ash is burned in a crucible at 1000°C for 15-20min , and then placed in a desiccator to cool to room temperature; pour the treated fly ash into a high-speed mixer and stir at a high speed, heat to 100°C, slowly sprinkle or mist spray in several times, and the dosage is 1% of the total amount of fly ash Potassium hydroxide, stirred at high speed for 10 minutes; then added stearic acid with 1.5% of the total amount of fly ash, stirred at high speed for 10 minutes and cooled; The ash is cross-linked and mixed at a high speed for 10 minutes to obtain a high polymer density regulator for plastic products.

Abstract

The invention provides a density conditioning agent for a high polymer and a preparation method of the density conditioning agent. The preparation method comprises the following steps of: modifying the coal ash which is taken as a raw material by an alkaline modifier and an acid modifier sequentially, and activating by a coupling reagent. The prepared density conditioning agent for high polymer is used for the high polymer products, and has the advantages of being high in applicability and high in compression strength, improving the flowability, the abrasive resistance, the carving resistance, the corrosion resistance, the pollution resistance and the weather fastness, being good in gloss controllability and flexibility, improving the high temperature-resistant fireproof performance, having the functions of heat preservation and heat insulation, being good in rubbing property, improving the work efficiency, being low in cost and the like; and the oil value can be reduced, the processability can be improved, the loading level can be increased, and the production cost of the high polymer product producing enterprises can be obviously reduced, so that the density conditioning agent is wide in application prospect in the industries, i.e. the plastics, the rubber, the asphalt and the like.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of renewable resources, in particular to a high polymer density regulator and a preparation method thereof, using fly ash as a raw material, and successively modifying the fly ash with an alkaline modifier and an acid modifier , and then activated with a coupling agent. Background technique [0002] In recent years, with the shortage of petrochemical raw materials and various resin raw materials, the cost of various polymer products based on petroleum has increased significantly. my country's economy has continued to grow rapidly for 30 years, creating a strong market demand for polymer products. Since 2010, polyolefin products from the Middle East and Southeast Asia that have signed free trade agreements have entered the Chinese market, making domestic companies lose their cost advantage. my country's general-purpose polyolefin product market has entered a state of fierce compe...
