Strengthen the formula of cellulose acetateTechnical field
The present invention relates to plastic formula, particularly relate to a kind of formula that strengthens cellulose acetate.
Background technology
Cellulose acetate is that Mierocrystalline cellulose carries out esterification with acetic acid or aceticanhydride under catalyst action, and a kind of thermoplastic resin obtaining, and cellulose acetate is applicable to produce transparent plastics product conventionally.Although the various modification cellulose acetate transparencies of using in current social are passable, production cost is high, and the quality after producing do not pass a test, and can not meet user's demand.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of formula that strengthens cellulose acetate, the formula of this enhancing cellulose acetate have improved transparency, strengthened physical strength, improved product quality, reduced the feature of the production cost of product.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of formula that strengthens cellulose acetate is provided, the formula of described enhancing cellulose acetate comprises cellulose acetate and additive, described additive comprises dispersion agent, coupling agent, weighting agent, impact modification agent and Nucleating Agent, described dispersion agent is polyacrylamide, described coupling agent is vinyltriethoxysilane, described weighting agent is glass fibre, described impact modification agent is ethylene propylene rubber, and described Nucleating Agent is Calcium Fluoride (Fluorspan).
In a preferred embodiment of the present invention, the shared weight percent of each composition of formula of described enhancing cellulose acetate is respectively cellulose acetate and accounts for 72.2%-75.9%, polyacrylamide accounts for 1.5%-2.1%, vinyltriethoxysilane accounts for 2.2%-2.6%, glass fibre accounts for 11.7%-12.9%, ethylene propylene rubber accounts for 5.6%-6.4%, and Calcium Fluoride (Fluorspan) accounts for 3.1%-3.8%.
In a preferred embodiment of the present invention, the shared weight percent of each composition of formula of described enhancing cellulose acetate is specially cellulose acetate and accounts for 72.9%, polyacrylamide accounts for 1.9%, vinyltriethoxysilane accounts for 2.5%, glass fibre accounts for 12.8%, ethylene propylene rubber accounts for 6.2%, and Calcium Fluoride (Fluorspan) accounts for 3.7%.
The invention has the beneficial effects as follows: the present invention strengthens the formula of cellulose acetate by add multiple additives in cellulose acetate, make to strengthen cellulose acetate improved transparency, strengthened physical strength, improved product quality, reduced the production cost of product.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
A kind of formula that strengthens cellulose acetate, the formula of described enhancing cellulose acetate comprises cellulose acetate and additive, described additive comprises dispersion agent, coupling agent, weighting agent, impact modification agent and Nucleating Agent, described dispersion agent is polyacrylamide, described coupling agent is vinyltriethoxysilane, described weighting agent is glass fibre, and described impact modification agent is ethylene propylene rubber, and described Nucleating Agent is Calcium Fluoride (Fluorspan).
Further, the shared weight percent of each composition of formula of described enhancing cellulose acetate is respectively cellulose acetate and accounts for 72.2%-75.9%, polyacrylamide accounts for 1.5%-2.1%, vinyltriethoxysilane accounts for 2.2%-2.6%, glass fibre accounts for 11.7%-12.9%, ethylene propylene rubber accounts for 5.6%-6.4%, and Calcium Fluoride (Fluorspan) accounts for 3.1%-3.8%.
Further, the shared weight percent of each composition of formula of described enhancing cellulose acetate is specially cellulose acetate and accounts for 75.3%, and polyacrylamide accounts for 1.6%, vinyltriethoxysilane accounts for 2.3%, glass fibre accounts for 11.9%, and ethylene propylene rubber accounts for 5.7%, and Calcium Fluoride (Fluorspan) accounts for 3.2%.
Further, the shared weight percent of each composition of formula of described enhancing cellulose acetate is specially cellulose acetate and accounts for 72.9%, and polyacrylamide accounts for 1.9%, vinyltriethoxysilane accounts for 2.5%, glass fibre accounts for 12.8%, and ethylene propylene rubber accounts for 6.2%, and Calcium Fluoride (Fluorspan) accounts for 3.7%.
The beneficial effect that the present invention strengthens the formula of cellulose acetate is: the present invention strengthens the formula of cellulose acetate by add multiple additives in cellulose acetate, make to strengthen cellulose acetate improved transparency, strengthened physical strength, improved product quality, reduced the production cost of product.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
