A kind of polymer composite material additive and its application

Abstract

The invention discloses a polymer composite material additive and an application thereof, belonging to the field of high-value utilization of biomass. The composite material additive is a mixture composed of inorganic particles and modified biomass oil. The biomass oil of the present invention has both dispersing and plasticizing effects, so that it is not necessary to add a large amount of plasticizers and modifiers to the polymer composite material, avoiding the pressure of industrial waste treatment, and is conducive to cost reduction and environmental protection .

Description

technical field [0001] The invention relates to the field of high-value utilization of biomass, which converts biomass oil into a processing aid for polymer materials through catalytic upgrading and product engineering concepts. Background technique [0002] Utilizing biomass to develop green chemical raw materials and functional materials has become the focus and frontier of sustainable development research. An efficient biorefinery process can convert biomass into small molecule liquid fuels and platform compounds, which can then be polymerized to produce related products. However, the complex technological process and the underutilization of the natural structure of biomass itself make the biomass conversion process low in technical economy and cannot be applied on a large scale. [0003] The "EU Horizon 2020 Plan" proposes that the new-generation biomass utilization strategy should be transformed from the existing "physical substitution" that draws on fossil energy to a...

Problems solved by technology

However, bio-pyrolysis oil contains hundreds of products (complex structure, high separation cost), which contain a large number of oxygen-containing functional groups (low calorific value), oligomers (high viscosity) and organic acids (high acidity, equipment corrosion) and other issues, there is a certain distance to replace fossil fuels

Generally, catalytic hydrogenation, catalytic cracking and other modification processes are used to deal with oxygen-containing functional groups and viscosity problems, but ultimately face the "two high and one low" problems of high energy consumption, high separation cost, and low added value.

[0005] The uniform dispersion of nanoparticles is the basis for constructing the nanostructure of fillers and polymers, and also determines the performance of composite materials. However, at present, inorganic nanoparticles have poor dispersion, are difficult to mix, and are prone to inorganic phase agglomeration in composite materials. body, not only is it difficult to achieve nanoscale recombination, the nano effect cannot be better exerted, and it may increase material defects, which limits its wide application

However, currently used silane coupling agents, titanate coupling agents, zirconate coupling agents, etc. are expensive, and require certain toxic organic solvents as auxiliary agents to modify the surface of inorganic nanoparticles, and cannot be used at room temperature. It is prepared under normal pressure, which increases the cost, so it is necessary to research and develop non-toxic inorganic filler dispersants
