Abstract

Disclosed are a cellulosic coating and a preparation method thereof. The cellulosic coating comprises additives, methylcellulose, water, a defoaming agent, bleaching powder and talcum powder. By weight, 550 parts of water, 12 parts of urea, 12 parts of polyethylene glycol, 21 parts of dibutyl phthalate and an appropriate quantity of ethylene glycol can be selected as the additives, and 0.11 part of tributyl phosphate can be selected as the defoaming agent. The cellulosic coating can be used for interior wall decoration of buildings such as homes, guesthouses, hotels and office buildings and has the advantages of no toxicity, odorlessness, flame retardance, simplicity in construction, low cost, high adhesive force, scrubbing resistance, high glossiness and durability, ageing resistance, fire resistance, long service life and the like.

Description

A kind of cellulose paint and preparation method

Technical field

The present invention relates to paint field, be specifically related to a kind of building coating, can be used for the cellulose paint of the inner wall of building decorations such as family, hotel, hotel, office building, there is the features such as nontoxic, tasteless, fire-retardant, easy construction, cost are low, and there is strong adhesion, scrubbing resistance; The advantages such as smooth finish, durability degree are strong, anti-aging, fire-retardant fireproof, and the life-span is long.

Background technology

Coating is coated in protected or decorated body surface; and the continuous film of firm attachment can be formed with coated article, normally based on resin or oil or emulsion, add or do not add pigment, filler; add corresponding additive, with organic solvent or the formulated thick liquid of water.Feature: 1. performance (1) opacifying power: opacifying power is usually with making the black and white lattice of regulation cover required coating weight to represent, the larger opacifying power of weight is less.(2) film adhesive: the bounding force representing film and basic unit.(3) viscosity: the size of viscosity affects workability, different constructional methods requires that coating has different viscosity.(4) fineness: fineness size directly affects planarization and the gloss of film coated surface.2. feature: (1) stain resistance.(2) weather resistance: comprise freeze-thawing resistant, abrasion resistance, ageing-resistant.(3) alkali resistance: decorative object mainly some basic materials of coating, therefore alkalescence is the key property of coating.(4) minimum film-forming temperature: often kind of coating all has a minimum film-forming temperature, different coating minimum film-forming temperatures is different.Interior wall coating is exactly the emulsion paint generally fitted up.Namely emulsion paint is emulsion coating, according to the difference of base material, is divided into polyvinyl acetate emulsion and the large class of ACRYLIC EMULSION two.Emulsion paint is thinner with water, be a kind of easy construction, safe, water-fastness, good permeability coating, it can mix different color and lusters according to different scheme of colo(u)r.Kind: water-based inner wall paint, oiliness interior wall paint, dry powder type interior wall paint, belongs to water-borne coatings, and primarily of water, emulsion, pigment, filler, additive five kinds of compositions are formed.Interior wall paint also makes interior wall coating comprise liquid coating and powder coating, and common emulsion paint, wall paint belong to liquid coating.Substantially be made up of water, pigment, emulsion, weighting agent and various auxiliary agent in the making composition of interior wall coating, these starting material are not containing what toxicity.As emulsion paint, may ethylene glycol in toxic mainly film coalescence aid with organic mercury in Fang Mildew agent.Cellulose paint is also known as cellulose lacquer.With the coating that cellulose ester or ether of cellulose are film forming material.Solvent then adopts volatile solvent formulated mostly, and volatilization is fast, and rapidly dry, paint film is solid, durable in use, bright and clean.And polishing of can waxing.Be applicable to metal, timber, leather etc.There are celluloid lacquer, cellulose acetate paint etc.

Summary of the invention

The object of the present invention is to provide a kind of building coating, can be used for the cellulose paint of the inner wall of building decorations such as family, hotel, hotel, office building, there is the features such as nontoxic, tasteless, fire-retardant, easy construction, cost are low, and there is strong adhesion, scrubbing resistance; The advantages such as smooth finish, durability degree are strong, anti-aging, fire-retardant fireproof, and the life-span is long.

Present invention employs such technical scheme: the material in described cellulose paint and weight proportion respectively: additive, methylcellulose gum, water, defoamer, chlorinated lime, talcum powder.

In the present invention, additive can select 550 parts, water, 12 parts, urea, polyoxyethylene glycol 12 parts, dibutyl phthalate 21 parts, ethylene glycol appropriate; Defoamer can select tributyl phosphate 0.11 part.

The present invention is specifically related to a kind of building coating, can be used for the cellulose paint of the inner wall of building decorations such as family, hotel, hotel, office building.

This product has the features such as nontoxic, tasteless, fire-retardant, easy construction, cost are low, and has strong adhesion, scrubbing resistance; The advantages such as smooth finish, durability degree are strong, anti-aging, fire-retardant fireproof, and the life-span is long.

Embodiment

Present invention employs such technical scheme: in described cellulose paint, material and weight proportion are respectively: additive, methylcellulose gum, water, defoamer, chlorinated lime, talcum powder.

In the present invention, additive can select 550 parts, water, 12 parts, urea, polyoxyethylene glycol 12 parts, dibutyl phthalate 21 parts, ethylene glycol appropriate; Defoamer can select tributyl phosphate 0.11 part.

Its preparation method is following steps:

Step one), add water in a reservoir, add urea, polyoxyethylene glycol, dibutyl phthalate, ethylene glycol successively in stirring, for subsequent use after abundant mixing and stirring;

Step 2), add methylcellulose gum and 15 parts, 100 DEG C of water in a reservoir, add 85 parts of cold water after 15min, stir rear for subsequent use,

Step 3) by step one), step 2) mixing of materials that obtains, stir, park 20h to completely dissolve after for subsequent use;

Step 4), by step 3) institute obtains in material and adds defoamer, add chlorinated lime, add talcum powder after stirring in stirring, to stir after 10min to obtain finished product.
