Abstract
The invention discloses a special pointing adhesive for a decorative aerated concrete block exterior wall. The pointing adhesive is an organic-inorganic compound with an organic component of butylbenzene latex and an inorganic component of cement. As performance of the butylbenzene latex and introduction of a plurality of multifunctional assistants, the pointing adhesive has better flexibility, bonding strength and wellability to the aerated concrete block than an ordinary pointing adhesive. The pointing adhesive of the invention contains two components of a slurry and a powder in separate packages. The slurry comprises water, butylbenzene latex, wetting agent, 1788 type polyvinyl alcohol aqueous solution, antifoaming agent and mildew inhibitor; and the powder comprises cement, fly ash and calcium carbonate powder. The slurry and the powder are cooperatively packaged according to a proportion.
Description
Technical field:
The present invention relates to the construction of a kind of decoration type exterior wall air-entrained concrete building block, to use special-purpose jointing adhesive, this jointing adhesive be organic-inorganic compoiste, and organic constituent is styrene-butadiene latex (butadiene-styrene copolymer emulsion, a SBL emulsion); Inorganic component is general cement.This jointing adhesive is because the natural characteristics of styrene-butadiene latex and the introducing through multiple functional aid, than common jointing adhesive have better snappiness, cohesive strength and to the wellability of air-entrained concrete building block.
Background technology:
It is pure organic type or organic-inorganic compoiste that common ceramic tile or ornamental blocks unit construction use jointing adhesive.Pure organic type jointing adhesive is bad to the wellability of air-entrained concrete building block, is not suitable for the jointing of air-entrained concrete building block wall face, and price is high, water tolerance is bad; The organic constituent of organic-inorganic compoiste jointing adhesive is polyacrylate emulsion or VAE emulsion; Inorganic component is general cement; The snappiness of this type jointing adhesive particularly low temperature flexibility is relatively poor; Wellability to air-entrained concrete building block is bad, also is not suitable for the jointing of air-entrained concrete building block wall face.
Summary of the invention:
Jointing and wall decoration and waterproof problem when constructing in order to solve decoration type exterior wall air-entrained concrete building block; The present invention provides a kind of special-purpose jointing adhesive; This jointing adhesive is a styrene-butadiene latex (butadiene-styrene copolymer emulsion; The SBL emulsion) and general cement be that main raw is processed, be a kind of organic-inorganic compoiste jointing adhesive.This jointing adhesive has good wellability to air-entrained concrete building block, than common jointing adhesive have better snappiness, cohesive strength and water-repellancy reliably, make exterior wall can keep the decorative effect of decoration type air-entrained concrete building block for a long time.
The present invention solves its technical problem and adopts following technical scheme:
Adopt styrene-butadiene latex (butadiene-styrene copolymer emulsion, SBL emulsion) as organic constituent; General cement is that inorganic component makes the organic-inorganic compoiste jointing adhesive.
Through the introducing of 1788 type polyvinyl alcohol water solutions, solve the mixing compatibility problem of styrene-butadiene latex and cement; Through the introducing of succsinic acid di-isooctyl Sulfonates wetting agent and fatty alcohol polyethenoxy ether class wetting agent, solve the wellability problem of jointing adhesive to the decoration type air-entrained concrete building block; Introducing through the water-based skimmer solves the bubble-related issues that jointing adhesive produces in the mix process before jointing; Introducing through the water mildow-proof agent solves the problem of going mouldy in the slurry storage process of jointing adhesive; Introducing through flyash solves the excessive problem of volumetric shrinkage in jointing adhesive drying and the setting and harden process.
Jointing adhesive of the present invention adopts the separately form of packing of slurry and powder two components when packing.The prescription of slurry is (quality %): water 5.0～10.0; Styrene-butadiene latex 25.0～55.0; Succsinic acid di-isooctyl sulphonate wetting agent 0.1～0.5; AEO wetting agent 0.1～0.5; 5%1788 type polyvinyl alcohol water solutions 5.0～10.0; Tributyl phosphate skimmer 0.02～0.05; Termil mould inhibitor 0.05～0.15.
The prescription of powder is (quality %): general cement 25.0～55.0; Flyash 6.0～25.0; Calcium carbonate powders 15.0～50.0.
The packing of slurry and powder cooperates (quality) than being: slurry: powder=1: 2.
The preparation procedure of slurry is: by the various raw materials of prescription weighing; Water, termil mould inhibitor are dropped in the appropriate containers, stir; Drop into 5%1788 type polyvinyl alcohol water solutions again, styrene-butadiene latex stirs; Dropping into Z 150PH succsinic acid di-isooctyl sulphonate wetting agent, AEO wetting agent and tributyl phosphate skimmer at last stirs.
The preparation procedure of powder is for mixing by prescription general cement of weighing and flyash.
The invention has the beneficial effects as follows: the polymeric film that styrene-butadiene latex forms can be adsorbed on cement stone interface securely; Form flyash, lime carbonate-cement stone-butylbenzene glued membrane space networks shape structure, give jointing glued membrane high-tensile, high bond strength, water-fast, acid-and base-resisting property and snappiness and deformability; Because the decoration type air-entrained concrete building block is had very high wellability; Jointing adhesive can be good spread in the decoration type air-entrained concrete building block seam; Make and produce bonding reliably, the decorative effect of permanent assurance decoration type air-entrained concrete building block exterior wall and water-repellancy, splitting resistance between jointing adhesive and the building block.The manufacturing cost of this organic-inorganic compoiste jointing adhesive is lower.
Below in conjunction with embodiment the present invention is described further.
Embodiment, non-limiting examples is described below:
