Description
Technical field
The invention belongs to the thermoplastic macromolecule material technical field, relate in particular to based on expanding material and make the compatible PVB sheet material of single double-deck material.Simultaneously, the invention still further relates to the preparation method of this kind PVB sheet material.
Background technology
PVB is the abbreviation of polyvinyl butyral acetal; It is a kind of polymkeric substance that forms through the Z 150PH of higher molecular weight and butyraldehyde condensation reaction under the catalysis of hydrochloric acid; Push and a kind of macromolecular material of moulding through the softening agent plasticizing, this product is the special plastic material of laminated safety glass.The PVB glued membrane becomes the necessary starting material of producing all kinds of shatter proof glasses with its good optical property, high temperature resistant, low temperature, mechanical property with to the good adhesive property of unorganic glass.When receiving extraneous intense impact, the PVB glued membrane can absorb impact energy, does not produce flinders, when having security feature, also has excellent sound insulation, light-operated, insulation, performance such as heat insulation, antifog, is ideal shatter proof glass work material.
PVB mainly is divided into by purposes: building safety glass with PVB film, automotive safety glass with PVB film and sun power PVB film.Its formula technique of PVB film, the product performance in three big fields have nothing in common with each other.Automotive safety glass mainly contains following kind with the PVB film: the transparent automotive safety glass of common grade has the PVB film, thermal isolation film (double-deck material) etc. of gradual change type color with PVB film, limit portion.Wherein double-deck material is a technology content very high " trilamellar membrane " product that Japanese ponding company releases, and its structure is a two-layer PVB material up and down, and the centre is one deck functional materials.The intermediary functional materials mainly is made up of two portions: jointing material and functional mass, functional mass is well-proportioned to be dispersed in the jointing material.Through experiment repeatedly, this double-deck material is after the effect that the forcing machine fusion is sheared, and the film that flows out die head presents fuzzy, as to send out mist phenomenon.The mist degree of film can reach more than 10%, almost becomes translucent material.Just because of this critical defect, the double-deck material of import PVB scrap stock become the not high substandard goods material of use value already on market.It can only be used for production oyster white PVB film or porcelain white PVB film, can not be used for the production of transparent PVB film.The price of market upper inlet individual layer scrap stock is 26000 yuan/ton, and the price of resin-oatmeal is 32000 yuan/ton, and the double-deck material of import PVB is limited owing to use range, and its price is merely 6000 yuan/ton, and difference in selling prices shows huge difference.
Summary of the invention
The object of the invention is intended to overcome the shortcoming that above-mentioned prior art exists; A kind of PVB sheet material that contains expanding material is provided; This kind expanding material can make PVB individual layer material well compatible with the double-deck material of PVB intermediate layer material; The drawback of mist does not appear bluring, sending out in the PVB sheet material of producing, and its optical property is unaffected.
Therefore, the object of the invention provides based on expanding material and makes the compatible PVB sheet material of single double-deck material, and it is to be prepared from following materials based on weight:
PVB resin-oatmeal: 90～110
Oxidation inhibitor: 0.2～0.5
UV light absorber: 0.2～0.5
Softening agent: 35～45
The double-deck material of PVB: 20～35
White dyes: 0.001～0.004
Expanding material: 1～7.
Further, described oxidation inhibitor is antioxidant 1010, and it can prevent more effectively that diaphragm is oxidized in the extrusion moulding process; Described UV light absorber is a ultraviolet absorbent uv-326, and its effect is that the pvb film that contains it has the ultraviolet function of absorption; Described softening agent is 3GO, and this softening agent is a PVB characteristic softening agent, contains hydroxyl and ehter bond in the molecular structure, can be well compatible with PVB, and it can make pvb film possess resistance to low temperature; Described white dyes is white dyes OB; Described expanding material is a poly glycol monomethyl ether, and its molecular structure is H-(O-CH
2-CH
2) n-O-CH
3, n≤22 wherein.
Further, described expanding material and PVB are mutually, polyoxyethylene glycol two (2 ethyl hexanoic acid) esters in the double-deck material of PVB middle layer are mutually compatible so that two (2 ethyl hexanoic acid) esters of polyoxyethylene glycol mutually with PVB consistency increase mutually.The molecular structure of the expanding material poly glycol monomethyl ether of choosing is: H-(O-CH
2-CH
2) n-O-CH
3,Wherein terminal hydroxy group-OH is contained in its molecule, ehter bond-O-in n≤22; Hydroxyl-the OH and the ehter bond-O-that contain in more little its molecule of poly glycol monomethyl ether of molecular-weight average are more, and the consistency of it and PVB is just good more.After poly glycol monomethyl ether adds co-mixing system; To form three-phase structure with two (2 ethyl hexanoic acid) esters of polyoxyethylene glycol and PVB; Poly glycol monomethyl ether plays the effect of similar connection phase; Two (2 ethyl hexanoic acid) ester phases of polyoxyethylene glycol, PVB are all mutually compatible with poly glycol monomethyl ether mutually; So just make two (2 ethyl hexanoic acid) esters of polyoxyethylene glycol increase with PVB reactive force mutually mutually, two (2 ethyl hexanoic acid) ester molecule chains of polyoxyethylene glycol and the interpenetrative probability of PVB molecular chain increase, thereby increase consistency.
Another object of the present invention is to provides the preparation method who makes the compatible PVB sheet material of single double-deck material based on expanding material, and it comprises the steps:
(1) the double-deck material of PVB is ground into particulate material with crusher, sends into polygonally in cone-type mixer through blast system, add the PVB resin-oatmeal simultaneously;
(2) oxidation inhibitor, UV light absorber, white dyes are added in the said mixing machine mix, simultaneously expanding material poly glycol monomethyl ether and softening agent are mixed the back and squeeze into mixing machine through volume pump;
(3) with the mixing machine chuck with the water quench below 18 ℃; Again this mixture is mixed stirring and add twin screw extruder after 25～35 minutes melt extrusion; Refilter, send into die head with toothed gear pump and carry out extrusion moulding, promptly get the PVB sheet material of double-deck material and individual layer material consistency.
Further, the oxidation inhibitor described in the step (2) is antioxidant 1010; Described UV light absorber is a ultraviolet absorbent uv-326; Described white dyes is white dyes OB; Described expanding material is a poly glycol monomethyl ether, and its molecular structure is H-(O-CH
2-CH
2) n-O-CH
3, n≤22 wherein; Described softening agent is 3GO;
Further, the melt temperature extruded of the twin screw extruder described in the step (3) is 145～155 ℃.
In the prescription of PVB sheet material of the present invention, add double-deck material; Through adding expanding material; Make these double-deck material in the process that melt extrudes, being on good terms of intermediate layer material is well mutually compatible with the PVB macromole, the phenomenon that weakens or can not occur being separated; That the pvb film of extruding does not produce is fuzzy, send out the drawback of mist, and optical property is unaffected.Simultaneously, the bilayer material owing to add appropriate umber at prescription of the present invention makes its production cost of product per ton reduce by 3500 yuan at least, is equivalent to the income that the company that can be every year creates 35000000 yuan.
The beneficial effect that is brought in order more to know the present invention, following form are that to detect the data list contrast by each item index with regard to the PVB sheet material that the product of the present invention draw and the usual prodn that does not carry out formula adjustment, international most advanced level product are detected in national chemical building material quality supervision and test center as shown in table 1:
