Description

A kind of covering with paint filler and preparation method based on gluten
Technical field
The present invention relates to the filler of coating.
Background technology
Existing coating is prepared using resin mostly, and resin plastic cement sense is strong, not environmentally.Certainly also there is addition face at present The coating of powder.Such as a kind of engine cylinder-body is disclosed in the patent document that Chinese Patent Application No. is 201110381121.1 to disappear Lost pattern casting coating and preparation method thereof, belongs to lost foam paint technical field, and problem to be solved is:There is provided a kind of Lost foam paint that being coated with property is good, good permeability and intensity are high and preparation method thereof;The scheme used for:Engine cylinder-body disappears Lost pattern casting coating, is formulated by following raw materials in parts by weight:100 parts of quartz sand powder;Sodium bentonite 5-10 Part;Cellulose 0.1-1;Resin 5-15 parts;Tween 0.01-0.08 parts;N-octyl alcohol 0.02-0.1;Flour 1-5 parts ;Pure water 60-90 parts;The present invention can be widely applied in existing various lost foam casting fields.In the technical scheme, Flour plays a part of being the bonding adhesive force for improving coating, and in the technical scheme, flour directly mixes with other raw materials, And the amount that flour takes is few, it is difficult to forms gluten, it is difficult to forming face manadesma.
It is special that a kind of water-soluble building coating is disclosed in the patent document that Chinese Patent Application No. is 95113092.7 Rubber powder.It is by calcium lime powder, sodium carbonate and flour(Starch)And auxiliary agent is mixed into uniformed powder material according to a certain ratio.This production Product do paint binder and do not have to heating, save the energy and artificial.Due to having excessive calcium oxide, calcium hydroxide in the present invention, it is right Air is in significant chemism, and two-step film forming can be achieved, and the soaking-resistant and the water-fast ability of scrubbing for making coating greatly improve.Gently Micro- make moist also is not easy gel caking, and storage period was up to more than 12 months.It will add 3-9 times of normal-temperature water in this product through 5-15 during use The stirring of minute, becomes the good liquid adhesive of colloid, and making base-material for production water-soluble building coating is used.Given birth to it The coating cost of production is low, quality is good.In the technical scheme, flour plays a part of being the bonding adhesive force for improving coating. In the technical scheme, flour directly mixes with other raw materials, and the amount that flour takes is few, it is difficult to forms gluten, it is difficult to shape Into gluten film.
The content of the invention
It is an object of the invention to provide a kind of covering with paint filler and preparation method based on gluten.Utilize the filling of the present invention Agent and preparation method, harmful chemical raw material is not added, environmental protection;Cost is low, is easy to film forming, water-tolerant.
To reach above-mentioned purpose, a kind of covering with paint filler based on gluten, comprise the following raw materials by weight percent:
Wet gluten 65%-80%
Alcohol 15%-30%
Cocoamidopropyl dimethylamine amine second lactone 2%-4%
Isopentyl aldehyde 2%-4%.
The preparation method of the described covering with paint filler based on gluten is:Wet gluten is put into a mixing bowl, adds alcohol, Mix slowly uniformly, then quick stirring, adding cocoamidopropyl dimethylamine amine second lactone in stirring stirs, then again plus Enter isopentyl aldehyde to stir to form thick white lotion.
Above-mentioned filler and preparation method, mucedin is contained in wet gluten, and mucedin is that institute is special in a kind of wheat flour A kind of colloid mixed plant protein having is mainly white by gliadin, glutenin, the molten albumen of acid, albumin and bladders Deng five kinds of compositions, wherein gliadin, glutenin is not soluble in water, and both albumen are also the main component to form gluten, its Molecular weight ranges are 30,000 up to up to ten million dalton(Da), have unique viscosity, elasticity, extensibility, film forming and Liposuction, there is many network structures in wet gluten, main component is used in coating for the filler of wet gluten, such as Fruit network structure is excessively firm, and wet gluten such as can become very hard because of firm network structure, so, just inapplicable as coating Filler uses, and therefore, in the present invention, adds a certain amount of alcohol, and alcohol can allow wet gluten to have network structure, and And it can be suppressed and form firm network structure, moreover, cocoamidopropyl dimethylamine amine second lactone has wetting, thickening and resisted The effect of oil, so, can form thick white lotion, and be unlikely to embody is the performance of wet gluten in itself, is suitable as The filler of coating uses.In the present invention without the harmful raw material of addition so that filler environmental protection, cost are also low.Isoamyl Aldehyde is had a water resisting property, and during stirring, isopentyl aldehyde is penetrated into wet gluten, with wet gluten collective effect to improve water proofing property Can, after the filler is used such as on leather base material, leather shrinkage and wrinkle resistance can be prevented, improves the durability of pressing.
Further, the preparation method of wet gluten is:It is by the flour that percentage by weight is 50%-60% and percentage by weight 40%-50% water is added and stirred in machine, flour is kneaded into dough with 40-50 revs/min of rotating speed, stirs the time as 20-50 points Clock, 10-30 minutes are placed, add 5~8 times of water rub washing, rubbed points for 3~4 times and to wash, the emulsion of wash-off be starch milk, placement As other purposes, it is wet gluten to be left thing.When manufacturing gluten, if content of starch is too high, filler can harden, so needing Wash clean is rubbed as far as possible, after being kneaded into dough, it is impossible to standing is too long, in case the solvation of gluten and water, forms firm net , there is insoluble matter in shape structure.
Further, the water content control of wet gluten is in 60%-70%.The water content of wet gluten it is unsuitable it is too low also should not mistake Height, water content is too low, is unfavorable for forming network structure, and water content is too high, and with the water capacity solvation easily occurs for gluten, forms jail Solid network structure.
Further, flour is Strong flour, protein content >=15.5% of Strong flour.
Further, contain mucedin in wet gluten, mucedin include gliadin, glutenin, the molten albumen of acid, Albumin and bladders are white.
Embodiment
With reference to embodiment, the present invention will be described in further detail.
