The PP nucleation reinforcement composition disclosed by the invention is used for modifying PP, especially non-glass-fiber-reinforced PP modification; and the PP nucleation reinforcement composition can effectively enhance the crystallization rate of the PP, increase the strength of the PP and improve the mechanical properties of the PP.
Description
Technical field
The present invention relates to a kind of production method of PP nucleation enhancing composition, particularly relate to recessed soil/wilkinite as the production method of PP nucleation enhancing composition.
Background technology
PP is because synthesis mode is simple, and raw material origin is rich, price is cheap, there is outstanding chemical resistant properties, motor energy, mechanics function, can be processed into injection-molded finished, slush molding finished product, film, thin slice and the fiber with all kinds of use, thereby become plastics output and increase one of the fastest kind, its output accounts for the 3rd in five large general-purpose plastics, so be generally used in the aspects such as articles for daily use, wrapping material, office appliance, electrical equipment and trolley part.Because PP is crystalline polymer, inside exists very large spherocrystal, cause that polyacrylic resistance to impact shock is very low, the rear compression phenomena of finished product is serious, do not have enough rigidity, size steadiness or the transparency etc. in application, this has seriously affected the application function of PP.So vast and numerous investigation person faces PP from aspects such as polymerization skill, moulding skill, matrix material skills and carries out modification, to improve its application function.In this, via process, participate in nucleator, the crystallization velocity of improvement moulding process, crystal grain thinning, with shock resistance function, the transparency and the glossiness of the finished product that improves, is to realize the conventional mode of polyacrylic high mechanization.
In recent years, along with the research and development of recessed soil resource are enriched in Jiangsu-Anhui, this rich magnesium silicate with rhabdolith structure of recessed soil is familiar with by people gradually.Recessed native crystal shape is bar-shaped (needle-like, fibrous), and diameter is 20 ~ 50nm, and length is 500 ~ 1500nm, belongs to 2 ︰ 1 type clay minerals, i.e. two-layer silicon-oxy tetrahedron, and one deck alumina octahedral, its molecular formula is: Mg

2more than/g, and rich surface is containing great amount of hydroxy group.Natural recessed soil is by cluster cluster crystal Shu Zucheng, is difficult to bring into play its Nano-property.
Summary of the invention
The object of the invention is: a kind of production method of PP nucleation enhancing composition is provided, and the PP nucleation enhancing composition obtaining by this production method improves crystallization rate, intensity and the dimensional stability of PP in PP modification.
Solution of the present invention is that this production method comprises the following steps:
(1) by the recessed soil of 10 ~ 40 object and wilkinite 3 ︰ 1 ~ 1 ︰ 3 mixing in mass ratio, and add water move to biodiversity content 40 ± 2%, with three rollers of Jian Ju≤2mm, push, obtain sheet composite soil;
(2) the sheet composite soil after step (1) is processed was stacked over 24 hours, by sheet composite soil and quality, than 1 ︰ 10, put into stainless steel troughing, then add the disperser composition of sheet composite soil quality 2%, high speed shear 1 hour, 70MP autoclaving, obtains suspension; Wherein, disperser composition is the mixture of Sodium hexametaphosphate 99 or sodium polyphosphate and small molecules weight polyacrylamide mass ratio 1 ︰ 1;
(3) the suspension cyclone classification after step (2) is processed, gets middle rank and dewaters, and obtains biscuit;
(4) 120 ℃ of biscuits after step (3) is processed are dried to quality moisture and are less than 2%, fragmentation, then add silane coupling agent and the calcium stearate mixture of its quality 10%, comminution by gas stream, obtains PP nucleation enhancing composition; Wherein, the mass ratio of coupling agent and calcium stearate is 1 ︰ 1.
Wherein, described recessed soil is dolomite type, and recessed native purity surpasses 60%; Wilkinite is calcium agent or sodium base, and crystal lamella is large.
Wherein, silane coupling agent is KH-550.
The present invention has the following advantages: organic and inorganic composition and the PP consistency of 1, producing are better, greatly improves the crystallization velocity of PP after fully disperseing, and increases the intensity of PP, improves PP erosion-resisting characteristics, has broad application prospects; 2, PP nucleation enhancing composition raw material sources are abundant, with low cost, manufacture PP nucleation enhancing composition production technique simple.
