Problems solved by technology

Putties in the past are generally composed of base materials (cement and organic polymers), fillers (heavy calcium, talcum powder, lime calcium, lime powder), water and additives, and polyvinyl alcohol, guar gum (a A kind of biomass chemical raw material), polymaleic anhydride, PVA, starch modified by heating and dissolving the prepared glue solution to improve the strength, not only requires energy for heating, but also it is difficult to dissolve evenly and completely for a while
[0003] Putty powder currently available on the market needs to be soaked in hot water at 50-85°C for 1-2 hours to dissolve and penetrate evenly when preparing the glue, and the glue is prone to surface "skinning" and the consistency becomes thinner during storage. , and even the layered phenomenon
The use effect is relatively simple, and it is difficult to coordinate in terms of bond strength, flexibility, and crack resistance.

Embodiment 1

[0037] A kind of fast reconciling putty or cement glue includes the following components and dosage: PVA1799: 20% (weight percentage, the same below), anionic PAM with a relative molecular weight of 3 million: 16%, HPMC with a viscosity of 120,000 centipoise: 5 %, ethanol: 3%, deionized water: 56%.

[0038] The preparation process of the glue solution includes weighing the raw material ingredients according to the above weight percentage ratio, mixing with a conical vertical screw mixer, a V-shaped mixer or a dough mixer, stirring for 0.5 hours, and passing through a shaking sieve or a vibrating sieve. Separation of large particles, etc., first made into powder, sampling and quality inspection against technical indicators, that is, the production of rubber powder products that can be quickly reconciled and dissolved. Then put it into a dough mixer, add ethanol and tap water, and stir for 40 minutes to prepare a glue solution with a solid content of 40% and a viscosity of 4600 ...

Embodiment 2~5

[0041] The manufacturing process of the rubber powder and the glue solution of embodiments 2 to 5 is basically the same as in the above-mentioned embodiment 1, and the raw material formula of each example is shown in Table 1:

[0042] Table 1 The raw material formula table of embodiment 2~5 glue Unit: %

Abstract

The invention belongs to the technical field of building adhesives and relates to gelatine powder and liquid cement for quickly mixing putty or cement. The gelatine powder mainly comprises the following components in parts by weight: 20-65 parts of PVA (Polyvinyl Alcohol), 10-42 parts of PAM (Polyacrylamide) and 4.0-18 parts of HPMC (Hydroxy Propyl Methyl Cellulose). The liquid cement is prepared by adding alcohol or deionized water to the gelatine powder. Compared with the existing gelatine powder and liquid cement, the product disclosed by the invention has the advantages that the preparation process is simple and convenient, the preparation process can be finished within one hour, the open time is 30 seconds, the liquid cement is transparent, the viscosity can be freely adjusted according to application demands, the cost is low, the storage is stable, and the like. If being used for mixing cement, building putty and the like, the gelatine powder and the liquid cement can accelerate the initial set of the cement and the putty, improve the binding power of the cement and the putty on a base material and improve the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis adhesives, and relates to a kind of glue powder and glue solution for quickly blending putty or cement, which is mainly used for replacing or partially replacing tap water in the process of making furniture, decoration and cement mortar, and can make the prepared mortar The adhesion to the base material or the wall is improved, reducing man-hours and saving costs. Background technique [0002] The construction industry consumes a large amount of cement and caulking and patching mud every day, while the furniture and decoration industry uses countless putties. Putties in the past are generally composed of base materials (cement and organic polymers), fillers (heavy calcium, talcum powder, lime calcium, lime powder), water and additives, and polyvinyl alcohol, guar gum (a A kind of biomass chemical raw material), polymaleic anhydride, PVA, and starch modified materials are heated and dis...
