CN102604464B - All-natural putty for interior walls of constructions - Google Patents

Abstract

All-natural putty for interior walls of constructions comprises, by weight, 50-150 parts of white cement, 250-350 parts of lime putty, 4.2-6.9 parts of alum, 200-300 parts of white stone powder, 1-2 parts of rubber tree tapping and 20-40 parts of water. The preparation steps of the all-natural putty include: (1) crushing the white stone powder and the alum; (2) mixing white cement with lime putty, feeding the mixture into a mixer, sequentially feeding the crushed white stone powder and the crushed alum into the mixer, and then adding the rubber tree tapping to be uniformly stirred; and (3) adding water into mixed dry solids which are discharged through stirring to obtain the all-natural putty finished product for the interior walls of the constructions. The all-natural putty for the interior walls of the constructions is good in technical performance and low in cost, resources can be saved and the environment can be protected as used raw materials are natural, non-toxic and non-hazardous, and the all-natural putty can be widely applied to treatment of batches of embedded layers of interior wall finishing processes of various constructions.

Description

A kind of pure natural inner wall of building putty

Technical field

The present invention relates to the wash primer of inner wall of building coating engineering, especially relate to a kind of putty of natural type inner wall of building.

Background technology

Putty (cry and filler again) is a kind of decoration gel material of smooth surface of wall, is a kind of thick slurry coating material, is that coating whitewashes front requisite a kind of product.As everyone knows, it is first to use after slaked lime levelling that common putty is criticized embedding, then criticizes common putty (old powder, batch wall ash), and so way, buries much hidden danger.Slaked lime in metope can with airborne carbon dioxide reaction, generate calcium carbonate, volumetric expansion, causes metope cracking and produces wall leakage phenomenon, the normal daily life that jeopardizes resident.Although building putties is a kind of base treatment material, its amount of being is large and wide, is a kind of material of construction that must attract great attention.The inner wall putty that past China's wide geographic area is produced generally adopts polyvinyl alcohol 801 glue, and carboxymethyl cellulose mixes the powder body materials such as dry powder, talcum powder.Although when import rubber powder and emulsion mixed powder material cost are low, but complex process, cost is higher.Particularly contain a large amount of objectionable impuritiess such as formaldehyde, can cause people's neural system impaired, when serious, can cause poisoningly and carcinogenic, to infant and elderly and infirm, endanger larger.

Summary of the invention

The problems referred to above that exist for prior art, the applicant provides a kind of pure natural inner wall of building putty.The present invention has good technical feature, and cost is low, and raw materials Nantural non-toxic, without harm, can economize on resources, protection of the environment, and batch inlay that can be widely used in the interior wall coating engineering of all kinds of buildings is processed.

Technical scheme of the present invention is as follows:

A pure natural inner wall of building putty, is comprised of the raw material of following weight part: 50 ~ 150 parts of white cements, 250 ~ 350 parts of lime putties, 4.2 ~ 6.9 parts, alum, 200 ~ 300 parts of white stone powders, 1 ~ 2 part of rubber myron, 20 ~ 40 parts, water.Preparation process is as follows:

(1) white stone powder, alum are pulverized;

(2) white cement, lime putty are mixed, drop in stirrer, then the white stone powder crushing, alum are dropped into successively, then add rubber myron to stir;

(3) stir mixing after discharging and do solid state again through adding the step of water, modulation obtains pure natural inner wall of building putty finished product.

The technique effect that the present invention is useful is:

In the raw material of product of the present invention, added rubber myron as jointing compound, rubber juice has good activity and bonding capacity.In addition, rubber myron is natural matter, nonpoisonous and tasteless, cheap, meets the requirement of recycling economy and environment protection.

In the raw material of product of the present invention, added alum as agglutinate, its effective constituent is Al ₂o ₃, SO ₃, can react with cement-hydrate, generate ettringite, can accelerate the α-TCP bone cement of cement.In addition, the waterproof action of alum has improved the performance of the water-tight corrosion-proof of putty.

In the raw material of product of the present invention, added white stone powder as strengthening agent, white stone powder is to form through mechanical disintegration, screening with white marble and calcite, and calcium carbonate content is high, and purity and whiteness are very high, fine size (5-1250 order), strong covering power, be particularly useful for putty powder.In addition, there is levelling, anti-abrasive property and certain opacifying power, can also improve processing characteristics and the effect of playing reinforcement and half reinforcement.

In the raw material of product of the present invention, added white cement as binding agent and water-resisting agent, white cement is the abbreviation of white portland cement, it is to take Calucium Silicate powder as major ingredient, the few portland cement clinker of iron degree content, through bleaching, adds material in the rigid gelling of the levigate white of making of appropriate gypsum.White cement has certain waterproof action in addition, also can be used for improving the water resistance of putty.

In product of the present invention, added lime putty, its main component is Ca (OH) ₂, there is strong basicity, can make the protein component of bacterium lose activity, raw material is carried out disinfection.In addition, lime putty can strengthen the workability of mixture, makes putty be difficult for dispersing, good water-retaining property.

Embodiment

The inventive method is implemented according to following steps:

(1) white stone powder, alum are ground into fine particle shape with pulverizer.

(2) white cement, lime putty are mixed, drop in stirrer, then the white stone powder crushing, alum amount is according to a certain ratio dropped into successively, then add rubber myron uniform stirring 70 ~ 150 seconds.

(3) stir mixing after discharging and do solid state again through adding the step of water, be modulated into thick liquid shape finished product.

Constructing operation step of the present invention:

Interior wall is crossed after cleaning, when temperature watering on the wall in 5 days in advance during at 2 ~ 10 ℃; Temperature is watering on the wall in 3 days in advance in the time of 10 ~ 25 ℃; Temperature was sprinkled water in when more than 25 ℃ for 1 day in advance on the wall.Cement mixed mortar bottoming (silt content is no more than 5%) for first pass, then uses the water of the certain proportioning of Product mix of the present invention, by mortar machine, stirs into putty, carries out the bottoming of whitewashing of interior wall, strikes off, then use headblock smooth with the long floating rule of 2m.
