Description
Technical field
The invention belongs to macromolecule chemical industry auxiliary agent technical fields, and in particular to a kind of polypropylene increase rigid toughening nucleating agent and its
Preparation method.
Background technology
Polypropylene is a kind of high crystalline polymer, and melt crystallization speed is slower in process, easily forms spherocrystal, thus
Influence the transparency of product and the impact strength of product.Nucleating agent it is effective addition can make polypropylene at relatively high temperatures out-phase at
Core improves crystalline rate, while improving the polyacrylic transparency and surface gloss and impact strength, tensile strength, modulus
And heat distortion temperature, and then the quality of product is improved, and simultaneously because crystallization rate is accelerated, molding cycle is shortened, thus it is big
The big benefit for improving enterprise.It is modified simple for process due to adding nucleating agent in polypropylene, additive amount is few, modified effect
Fruit is apparent, therefore the use of nucleating agent is increasingly extensive.Polypropylene nucleater need to have fine uniform structure distribution, insoluble, nontoxic or low
Poison has the features such as crystal plane by polypropylene quick adsorption.Polyacrylic crystal habit mainly has α (monoclinic crystal) and β (six sides
It is brilliant) etc. four kinds of crystalline forms, wherein α crystalline substances are most commonly seen and most stable of a kind of crystalline forms in crystalling propylene.α crystalline substance density is 0.94g/
cm3, fusing point is about 165 DEG C, it has the effects that increasing rigid, raising heat distortion temperature, creep resistant, reduction turbidity.β crystalline substances are common
Content is brilliant much smaller than α in crystalling propylene, and β crystalline substance density is 0.92g/cm3, fusing point is about 155 DEG C, in order degree and thermostabilization
Aspect of performance can improve the shock resistance and heat distortion temperature of polypropylene articles, make polypropylene simultaneously also below α crystalline substances, beta crystal
This for the shock resistance and heat distortion temperature while raising being difficult to realize present in preparation reaches organic unification to contradiction.
In addition, beta crystal also assigns polypropylene articles good porous structure, improve its gas permeability, impressionability etc..Alpha-crystal form nucleating agent
It is that there is induction acrylic resin to be nucleated with alpha-crystal form, improves the crystallization temperature of product, crystallinity, crystallization rate simultaneously makes crystal grain ruler
The nucleating agent of very little imperceptibility function, beta crystal-type nucleater is then that acrylic resin can be induced to be crystallized with beta crystal, and product can be improved
Impact resistance, heat distortion temperature and porosity rate.After adding beta crystal-type nucleater, impact strength can obtain significantly polypropylene
Raising, i.e. toughness increases, but polyacrylic tensile property and bending property are often declined at this time, and alpha-crystal form nucleating agent
Addition can significantly improve polyacrylic stretching and bending property, but its impact strength can decline.How polypropylene is improved simultaneously
Rigidity and toughness become a critical issue.

Main component of the benzylidene sorbitol as reinforcement nucleating agent, dibenzal sorbitol are α crystalline substance nucleating agents, have make polypropylene at
The basic function of core, and easily dispersion, but its increasing rigidity can be general；Increasing rigid auxiliary agent can rigidly be added the increasing of dibenzal sorbitol
By force, the rigid auxiliary agent of increasing being mixed to get especially with nano silicon oxide, sodium metasilicate, glass fibre and calcium carbonate, with two benzals
Sorbierite can make 1.5 times of polyacrylic strength enhancing or more after combining；Dispersant makes the inorganic constituents in raw material and organic principle
Can be evenly dispersed, Phthalate, suberate, stearate are carboxylate, and beta crystal is can act as in polypropylene
Nucleating agent acts on, and with synergistic effect, polypropylene impact strength is enable to be greatly enhanced.With dibenzal sorbitol,
After increasing rigid auxiliary agent combination, polyacrylic mechanical property can be further promoted.
As an optimization, the Phthalate is M-phthalic acid zinc, M-phthalic acid calcium, M-phthalic acid magnesium, isophthalic
Aluminum diformate, terephthalic acid (TPA) magnesium, terephthalic acid (TPA) calcium, terephthalic acid (TPA) zinc, at least one of terephthalic acid (TPA) aluminium.
The dispersant is polyethers, polyglycols, titanate coupling agent, dimethylsiloxane methyl cellulose, polyethylene glycol
At least one of.
As an optimization, the suberate is suberic acid magnesium, at least one in calcium suberate, suberic acid aluminium, suberic acid zinc
Kind.
As an optimization, the stearate is odium stearate, in calcium stearate, magnesium stearate, zinc stearate, aluminum stearate
It is at least one.
As an optimization, the particle size of the nano silicon oxide is 100 nanometers hereinafter, the granularity of nano silicon oxide is smaller,
It is more easily dispersed in increasing rigid toughening nucleating agent, and the increasing for increasing rigid toughening nucleating agent rigidly can be stronger.
The present invention also provides a kind of methods for preparing polypropylene and increasing rigid toughening nucleating agent, include the following steps：
Step 1 weighs each raw material according to parts by weight respectively, spare；
Step 2, a certain amount of water, water temperature will be added after dibenzal sorbitol, stearic acid salt and dispersant in step 2
It is 60 DEG C, is stirred 30 minutes with the rate of 150~300r/min or more, then sequentially add Phthalate, increases rigid auxiliary agent, pungent
Diacid salt and a certain amount of water, are made into the solution of 20-25%, and polypropylene increasing is obtained after stirring 0.5 hour or more stirring
Rigid toughening nucleating agent mixed liquor.
The mixed liquor that step 2 is prepared is ground by step 3 with grinder, and grinder rotating speed 600-700r/min is ground
Time consuming is 30-45 minutes.
Step 4 filters the mixed liquor after grinding, filter cake drying, at final finished.
As an optimization, the polypropylene reinforcement nucleating agent grinding grain size is less than 15um.
As advanced optimizing, the polypropylene obtained in the step 4 increases rigid toughening nucleating agent filter cake, by it in 100-
140 DEG C of drying increase rigid toughening nucleating agent to get to powdered polypropylene.
Advantageous effect
Beneficial effects of the present invention are as follows：
(1), polypropylene provided by the invention increases rigid toughening nucleating agent, using dibenzal sorbitol as reinforcement nucleating agent
