Abstract
The invention discloses a manufacturing method of polyvinylidene difluoride special-purposed white master batches for a solar-energy backboard membrane. According to the invention, polyvinylidene difluoride, polymethyl methacrylate and inorganic titanium pigment are adopted as raw materials; low-molecular-weight polyethylene wax and a fluorine-containing active dispersant are adopted as a dispersant and a surface modifier for the inorganic titanium pigment; the materials are subject to high-speed mixing and dispersion; the mixture is subject to extrusion granulation by using a double-screw extruder, such that a finished product is obtained. The special-purposed coloring master batches provided by the invention are advantaged in that: coloring capacity of the titanium pigment is high; dispersion uniformity of the titanium pigment in a membrane product is high; the cost is low; and the preparation technology is simple. The method has a good application prospect in the field of solar-energy backboard membrane processing.
Description
Technical field
The present invention relates to a kind of method of manufacture of Masterbatch, particularly the method for manufacture of the special-purpose white master batch of PVDF sun power backboard film.
Background technology
Development along with photovoltaic industry; Sun power backboard film demand with the PVDF preparation increases severely; At present domestic still do not have enterprise to prepare sun power backboard film with PVDF, the main dependence on import of domestic photovoltaic industry, and homemade PVDF Masterbatch more of no use is mixed with the backboard film; Therefore, the PVDF special color master batch of our company's exploitation has the leading position in industry.
Pure PVDF film article is water white, and transmittance is higher, is penetrated by sunshine easily.Sun power backboard film requires transmittance to be lower than 20%, and ultraviolet resistance, anti-steam and work-ing life of long-term (about 20 years) is arranged, and adds the transmittance that PVDF film special color master batch can improve film, can reach to be lower than 20%.Add the inorganic titanium white powder in the Masterbatch,, can give film article resistance light action through the resistance look of inorganic titanium white powder.The base-material PVDF is a macromolecule organic material; The affinity of it and inorganic titanium white powder is very poor; If the inorganic titanium white powder is not carried out pre-treatment; The inorganic titanium white powder that particle is very thin is difficult to be uniformly dispersed in plastic body, causes film article painted inhomogeneous, has influenced the visual appearance and the work-ing life of goods.In order to improve dispersiveness and the tint permanence of white titanium pigment in the PVDF base-material; Adopt some processing aids to anticipate inorganic titanium white powder surface at present; Improve the compatible affinity of white titanium pigment and base-material, with the part PVDF, gather the methylpropanoic acid methyl esters and mix to extrude and process the special color master batch that film is used with twin screw extruder.At present; People generally adopt tung oil or some the low-molecular-weight paraffin surface treatment agent as white titanium pigment; But these treatment agents are unsatisfactory in the dispersive ability of plastic body to white titanium pigment, and in casting film, coloration efficiency and homogeneity all do not reach specification of quality.
Summary of the invention
Technical problem to be solved by this invention provides the method for manufacture of the special-purpose white master batch of a kind of PVDF sun power backboard film; The present invention utilizes low-molecular-weight polyethylene wax that reasonable characteristic of the adsorptivity of inorganic titanium white powder and fluorine-containing active dispersion agent are had fine modification blending dispersion action characteristic to the PVDF molecule; At first handle the inorganic titanium white powder with low-molecular-weight polyethylene wax and fluorine-containing active dispersion agent; Improve the affinity and the dispersiveness of inorganic titanium white powder and PVDF, polymethylmethacrylate; Again with the fusion of part PVDF by the twin screw extruder extruding pelletization, process the special color master batch that can be used for curtain coating system PVDF film article.
In order to solve above-mentioned technical problem, technical scheme of the present invention is: the method for manufacture of the special-purpose white master batch of PVDF sun power backboard film:
1) adopting PVDF, polymethylmethacrylate and inorganic titanium white powder is raw material, and the mass percent of above-mentioned raw materials is:
PVDF 50%-55%
Polymethylmethacrylate 5%-10%
Inorganic titanium white powder 28%-40%
Utilize low-molecular-weight polyethylene wax, the fluorine-containing active dispersion agent surface-modifying agent as the inorganic titanium white powder, the mass percent of above-mentioned low-molecular-weight polyethylene wax, fluorine-containing active dispersion agent is:
Low-molecular-weight polyethylene wax 3%-15%
Fluorine-containing active dispersion agent 2%-10%
2) inorganic titanium white powder, PVDF, polymethylmethacrylate and low molecular weight polyethylene wax, fluorine-containing active dispersion agent are mixed in high-speed mixer, under 80-100 ℃, grind fully then with shredder;
3) ground white titanium pigment and base-material are carried out fragmentation, guarantee above-mentioned each component thorough mixing;
4) under 160-200 ℃, use the twin screw extruder extruding pelletization, be prepared into PVDF sun power by the special-purpose white master batch of backboard mould.
Said fluorine-containing active dispersion agent is ammonium perfluorocaprylate, perfluor-2.5-dimethyl-one 3.6 one dioxa n-nonanoic acids or perfluor oxygen in ninth of the ten Heavenly Stems base benzene sulfonate.
Preparation technology of the present invention is simple and easy to control; The preparation process does not have waste water, waste gas produces; The Masterbatch of producing is in the casting film coloring process; Have coloration efficiency height, uniform coloring degree height and the low advantage of cost, for curtain coating system PVDF film field provides a kind of new high-quality color master-batch product.
