Abstract
With CMS (carboxymethyl starch) is film-forming binder, with upright powder, three fly powder (wollastonite powder), talcum powder is pigment and pigment extender, ultramarine is the interior wall concentrated powder coating that whitening agent is made, and stirs with cold water during use, its cover-up surface is big, strong adhesion.
Description
The present invention relates to the decorative paint in the material of construction.
Modern age, building construction inside was whitewashed and decoration is absolutely necessary, it is a lot of that interior wall is whitewashed used coating variety, concludes and get up roughly to be divided into polyvinyl alcohol (PVC) and acetals thereof, Vinyl Acetate Copolymer class, olefin interpolymers such as vinylchlorid, vinyl acetate between to for plastic class, water glass class and starch based etc.Water soluble paint-DVC wherein, water glass and starch based-have preparation is easy, stable performance, water-soluble, good decorating effect and relatively be used widely for advantages such as low cheapnesss than water-insoluble coating.In belonging at present, low-grade and the most widely used kind is the common film-forming binder that constitutes of polyvinyladehydes and water glass, adds pigment extender, tensio-active agent etc. and the coating made, for example code name is 106 coating variety.This coating is except the waterproof of preserving water glass coating, characteristics such as anticorrosion, durable, overcome original film difficultly do, easily sclerosis, dry and cracked shortcoming, and eliminate the shortcomings such as meeting water easily expands, embrittlement of filming when using PVC coating separately.Coating-code name that the class coating material that polyvinyl alcohol and formaldehyde condensation form is made is 808,815 etc.-goodish performance also arranged.This its filmogen of class coating all is synthetic macromolecular compounds, they manufacture method itself and the technology of making coating all have certain degree of difficulty, therefore its cost is higher slightly than using mineral compound or natural process material, energy consumption is bigger in this class coating making processes, this class coating finished product is an aqua in addition, wherein contain big water gaging, this is a kind of waste for transportation.What be worth to propose is that polyvinyl alcohol series coating uses its aging speed of back slow and pollution speed is fast, and the general time is the color mutability after the brushing metope is complete.More low-grade interior wall coating, as water glass coating, starch coating is eliminated gradually owing to poor-performing.
The objective of the invention is to find a kind of new prescription of finishing material, its raw material particularly film forming caking agent is easy to get and is cheap; Coating is simple for production; Coating is a kind of thickened solid, only adds a certain amount of cold water during use and stirs a little and can brush; The brushing usage quantity is little, and effective, i.e. strong adhesion, dry linting and keep pure white in the long period not after doing.
The present invention adopts the CMS(carboxymethyl starch) as film-forming binder, CMS is the product of starch deep processing, be its adhesive property greatly to be strengthened the starch carboxymethylation.It is pigment and pigment extender that the present invention adopts upright powder, talcum powder and three to fly powder (wollastonite powder), is whitening agent with ultramarine.The raw materials used kind of the present invention, specification and prescription are:
Raw material name of an article granularity order proportioning %
CMS ≤100 9.0～20.0
Upright powder≤325 10.0～20.0
Three fly powder≤325 45.0～50.0
Talcum powder≤325 5.0～25.0
Ultramarine≤325 1.5～5.0
Every kind of proportioning raw materials all can as above fluctuate in the proportioning, but each per distribution ratio sum of forming still is 100%.By above-mentioned prescription that mixing of materials is even, heat sealing promptly becomes product in the plastics bag of packing into.During use plastics bag is opened material and pour in the container, the cold water that adds 3～3.5 times stirs after 10 minutes and can brush.The pure white thickness of slurry outward appearance, pH value are 7～8, and opacifying power is that every square metre of area restrains with slurry 250～300, and strong adhesion is done back not shedding of erasing.The concentrated powder coating long-term storage is never degenerated.
Characteristics of the present invention are: use CMS both to strengthen cohesive force, again because of its solubleness in cold water is big, need not heating even boil or add caustic soda, to stir the back available, energy-conservation, convenient so coating adds cold water.Courageously use three of vast scale to fly powder in this prescription, this point is different from other kind coating.Manufacturing process of the present invention is very simple.The most outstanding is that product is a solid, and packing is simple and be easy to transportation, thereby has avoided a large amount of " fortune water " and the waste that causes.Also be very easily for the user, and cost cheap also be advantage of the present invention.
Embodiment
Concentrated powder coating is by following prescription
Name of an article granularity order proportioning %
CMS ≤100 13.50
Upright powder≤325 16.50
Three fly powder≤325 49.89
Talcum powder≤325 20.00
Ultramarine≤325 0.15
Raw material mixed grind evenly, weighing is packed in the plastics bag, heat sealing.
Claims (2)
1, the decorative paint of making by film-forming binder, pigment and pigment extender, whitening agent, feature of the present invention is to use CMS (carboxymethyl starch) to be film-forming binder, upright powder, three flies powder (wollastonite powder), talcum powder is pigment and extender pigment, ultramarine forms for the whitening agent mixed preparing, and its prescription is as follows
CMS 9.0～16.0%
Upright powder 10.0～20.0%
Three fly powder 45.0～50.0%
Talcum powder 5.0～25.0%
Ultramarine 1.5～2.0%
Various proportioning raw materials all can as above fluctuate in the proportioning, but each per distribution ratio sum of forming still is 100%.
2, according to claim 1, the granularity requirements that the invention is characterized in various raw materials is CMS≤100 orders, other≤325 orders.
