Abstract

The invention provides a manufacturing method for a gypsum-based tile binder. The manufacturing method comprises the following steps: mixing slightly expanded gypsum powder with slightly contracted cement and aggregate and doping a proper amount of bentonite at the same time; then carrying out conventional stirring and homogenizing; and carrying out packaging after inspection is passed; wherein the gypsum powder is alpha powder, beta powder or mixed alpha and beta powder, and accounts for 20 to 50% of the weight of the binder, the cement is Portland cement, sulphate aluminum cement or other cement, and accounts for 9 to 30% of the weight of the binder, the aggregate is ground silica, slag powder or other ore powder and accounts for 10 to 60% of the weight of the binder, and the bentonite is calcium bentonite or sodium bentonite, and accounts for 1 to 5% of the weight of the binder. The method employs organic combination of the gypsum powder, the cement, the aggregate and the bentonite, so the prepared binder enables a tile to be better matched with a wall or floor when applied to bonding of the tile; and thus, cracking and falling of tiles on the wall are greatly reduced, undesirable phenomena like arching of tiles on the floor is prevented, environmental pollution is decreased, civilized construction is realized, and in particular, construction cost is lowered, so the binder is applicable to popularization and application in the construction industry or interior decoration industry.

Description

A kind of manufacture method of gypsum base ceramic tile bond

3 technical fields

The present invention relates to a kind of manufacture method of gypsum base ceramic tile bond, belong to building material field.

Background technology

Architectural pottery has been one of main building and ornament materials, and the annual architectural pottery that uses in the whole nation reaches more than 10,000,000,000 square metres, and only bonding ceramic tile just need consume cement 200,000,000 tons;

It should be pointed out that and pursue simple and direct form of construction work due to construction site workman and improve operating efficiency, general requirement is with 1 ︰ 3 cement mortar sticking brick, and workman directly pastes with cement paste, not only increase stickup cost, and have influence on the work-ing life of ceramic tile, even jeopardize building safety.Its reason is that the coefficient of expansion of cement paste and ceramic tile does not mate, and is cement, the damp and hot expansion cycles of ceramic tile back and forth result in ceramic tile and metope or ground and peel off, if the ceramic tile of vertical plane wall comes off often injure pedestrian by a crashing object; Cause some dangerous accidents.At present, the ceramic tile that kitchen and toilet are pasted, within 2 ~ 3 years, just start be full of cracks afterwards, the phenomenon that the ceramic tile that Stall or attic ground are pasted arches upward happens occasionally, everything certainly with the water-intake rate of ceramic tile about (more easily there is this type of phenomenon in general Shi matter brick, the pottery brick being greater than more than 5% that absorb water), but major cause uses neat cement slurry to paste and causes, therefore, the problem that the problems referred to above just solve building safety and ceramic tile work-ing life is solved.We know, occur that some contain organic ceramic tile bond for also arising at the historic moment in the market that solves the problem, but due to the work-ing life that buildings general requirement is longer, ceramic tile is as finishing material is direct and body of wall colds and heat succeed each other, drying and watering cycle, even obnoxious flavour and intensive ultraviolet contact, and the caking agent of bonding ceramic tile need bear above-mentioned environment equally, the weathering resistance containing organic binding agent, weather resistance, security is made all to need the problem solved.

Summary of the invention

The object of this invention is to provide a kind of manufacture method of gypsum base ceramic tile bond, in order to overcome the above-mentioned defect that existing neat cement slurry and organic binder bond sticking brick bring, to improve the cohesiveness of caking agent, workability and water-retentivity, reach both convenient constructions, fundamentally can solve again tile paste poor stability, high, the inefficient difficult problem of cost in the past, the building wall that stickup is gone out or floor ceramic tile firmly, safety, operating efficiency is high, and comprehensive cost is low.

For solving its technical problem, the technical solution used in the present invention is: adopt the terra alba of microdilatancy to mix with the cement and aggregate of micro-contraction, mix appropriate wilkinite simultaneously, then forms through convention stir, homogenizing, after the assay was approved packaging; Wherein said terra alba is α powder, β powder, or α, β powder mix, accounts for 20% ~ 50% of weight percent;

Wherein said cement is silicate cement, aluminosulfate cement or other cement, accounts for 9% ~ 30% of weight percent;

Wherein said aggregate is ground silica, slag powders or other breeze, accounts for 10% ~ 60% of weight percent;

Wherein said swelling soil series calcium-base bentonite, sodium bentonite, account for 1% ~ 5% of weight percent.

Terra alba described in the present invention, cement, aggregate, bentonitic content and the mechanism of action are as follows:

1. terra alba: 20% ~ 50% α, β terra alba has certain intensity after adding water and stirring, and have certain swelling property, thus counteract cement dry shrinkage, be not enough to when terra alba is less than 20% improve the contraction of offsetting cement, when more than 50% time affect quality on the contrary because of overplumping, even increase cost;

2. cement: 9% ~ 30% cement is the most large gelling material, wide material sources are cheap, it can act synergistically with terra alba aggregate, ceramic tile and metope or ground are bonded together, can sticking strength be affected when cement is less than 9%, more than 30% time can improve swelling property and also can increase cost;

3. aggregate: 10% ~ 60% comparatively cement is low because the coefficient of expansion of aggregate is general, particularly price is lower, thus not only can improve the performance of binding agent, but also can reduce its cost.Be not enough to improve cost performance when aggregate is less than 10%, more than 60% time affect the intensity of binding agent;

4. wilkinite: 1% ~ 5% can improve workability and other workability of binding agent significantly due to its strong plasticity, water-retentivity, improves not obvious when wilkinite is less than 1% to workability, and more than 5% time can reduce intensity and impact uses.

In a word, a kind of gypsum base ceramic tile bond of the present invention and existing cement or sand-cement slurry, organic binder bond ratio, not only reduce the coefficient of expansion significantly, its weathering resistance is improved significantly, and the stirring that adds water during construction can use, very convenient, particularly than other products long service life, cheap.
