Abstract
The invention discloses a caulking anti-crack mortar comprising the following components, by weight: 10-30 parts of calcined gypsum, 5-15 parts of cement, 50-75 parts of sand, 8-20 parts of fly ash, 1-5 parts of mineral powder, 1.5-3 parts of re-dispersible latex powder, 0. 2-0.5 parts of a water-retaining agent, 0.5-3 parts of an extender, 0.5-3 parts of an activator, 0.1-0.3 parts of polypropylene fiber, 0.15-0.2 parts of a water reducing agent, 0.2-0.5 parts of a waterproof agent, and 0.02-0.2 parts of a retarder. The mortar has the advantages of simple preparation and convenient construction. The prepared caulking anti-crack mortar has high bonding strength, and does not shrink, such that the flatness of a joint is ensured, and cracking and falling phenomena are avoided.
Description
Technical field
The present invention relates to a kind of joint filling anticracking grout.
Background technology
Aerocrete block partition batten, gypsum lath, matrix material batten etc. are in construction processing plate seam process, to smear seam mortar, because ordinary mortar exists larger shrinkage value, the easy phenomenon producing cracking, come off of long duration, has a significant impact for wall decoration and security.Have smear seam mortar due to self-strength excessive, the tensile stress produced sheet material during contraction is greater than the bonding force of sheet material self, causes breakage to sheet material.
Summary of the invention
A kind of joint filling anticracking grout that the present invention proposes, solves the problem of cracking between plate seam from source.
In order to achieve the above object, the invention provides a kind of joint filling anticracking grout, comprise the component of following weight part: plaster of Paris 10-30 part, cement 5-15 part, sand 50-75 part, flyash 8-20 part, breeze 1-5 part, can dispersed latex powder 1.5-3 part, water-holding agent 0.2-0.5 part, swelling agent 0.5-3 part, exciting agent 0.5-3 part, polypropylene fibre 0.1-0.3 part, water reducer 0.15-0.2 part, water-resisting agent 0.2-0.5 part, retardant 0.02-0.2 part.
Sulplo-aluminate class swelling agent selected by described swelling agent; The length of described polypropylene fibre is less than or equal to 9mm; Vltra tears selected by described water-holding agent; Described exciting agent is inorganic salts exciting agent; Described sand selects 20-40 object quartz sand or river sand.
A kind of joint filling anticracking grout provided by the invention, the component of the following weight part of optimum proportioning: the plaster of Paris 15 parts, cement 6.4 parts, sand 68 parts, 11 parts, flyash, breeze 1.8 parts, can dispersed latex powder 1.8 parts, water-holding agent 0.26 part, swelling agent 1.27 parts, exciting agent 1.2 parts, polypropylene fibre 0.15 part, water reducer 0.16 part, water-resisting agent 0.45 part, retardant 0.08 part.
The present invention compared with prior art has following improvements: the present invention's gesso, cement, flyash etc. prepare gypsum based composite cementing material, joint filling anticracking grout prepared by admixture additive and sand, has better cementability, water-repellancy, weather resistance than pure gypsum mortar; Plastering itself has good dimensional stability, and gypsum also has the characteristic of microdilatancy in water condensing process meeting, and this makes joint filling mortar of the present invention can well be combined with sheet material at the use initial stage, seam crossing is filled more closely knit; The present invention adds cement and flyash, and hydrated reaction product is filled up and made goods closely knit around the crystallization of dihydrate gypsum, increases anti-water resistance; Joint filling anticracking grout of the present invention in order to after ensureing to meet water reaction due to moisture evaporation, react the volumetric shrinkage that causes, add appropriate swelling agent, make joint filling mortar react the later stage and do not shrink; The present invention makes full use of the impact of retardant on plastering intensity, the retardant suitable according to the board selection connected, and ensures that the intensity of joint filling mortar is meeting under respective standard, basically identical with the intensity of bonding sheet material, avoids the phenomenon occurring drawing crack sheet material; Meanwhile, the crack resistance of admixture polypropylene fibre reinforced mortar; The sand selected is 20-40 object quartz sand or river sand, has good crack resistance.
Joint filling anticracking grout preparation of the present invention is simple, easy construction, applied range, and the joint filling anticracking grout bonding force of preparation is strong, does not shrink, ensure that the planarization of junction, stop cracking phenomena.
