CN103274661A - Rapid solidifying sizing agent for in-situ spraying - Google Patents

Abstract

A rapid solidifying sizing agent for in-situ spraying belongs to the field of buildings. The rapid solidifying sizing agent comprises cement, a plaster, swelling polyphenyl granules, sand and additives. The proportions of the various components are adjusted according to the requirements on indexes like the strength and the water resistance of a wall body, so that the defect that the conventional sizing agent cannot reliably guarantee the comprehensive performance and the construction efficiency of the wall body is overcome.

Description

The rapid solidification slurry is built in a kind of on-the-spot spray

Technical field

Belong to building field, particularly a kind of material of construction that uses in the walling body manufacture process that sprays.

Background technology

Slurry is built in existing on-the-spot spray, in spraying process, because the particle diameter of expansion polystyrene is improper, causes the spraying equipment cisco unity malfunction easily, and has any problem during the metope leveling of spraying back; Adopt Portland cement, the body of wall after the feasible spraying influences the integrality of wall energy in conjunction with bad; Adopt the ratio of gypsum improper, cause coagulation result undesirable, efficient is built in the influence spray or quality is built in spray

Summary of the invention

At the defective of prior art, the present invention proposes a kind of on-the-spot spray and builds the rapid solidification slurry, comprises cement, gypsum, expansion polyphenyl particle, sand, additive; The ratio of each component is according to strength of wall body, and the requirement of indexs such as water tolerance is adjusted, and it is characterized in that: the gypsum weight ratio of its integral part is 40%-54%, 56%-78%, and cement adopts short-term strength cement, the particle diameter 3-5 millimeter of expansion polystyrene; Have suitable setting rate, can realize the building wall method of on-the-spot spray walling body, and can guarantee combination and the setting rate of each component of body of wall reliably, self-heat conserving, in light weight, there are not advantages such as contraction.

The invention has the beneficial effects as follows,Owing to adopted suitable plaster ratio, effectively guaranteed efficient and wall performance that spray is built; Adopted short-term strength cement, can allow the abundant good binding of component such as cement and keel and gypsum, and guarantee the over-all properties that the rapid solidification slurry is built in on-the-spot spray, adopted the expansion polyphenyl particle of particle diameter 3-5 millimeter, be more suitable for spray and build equipment work, increase work efficiency, both guaranteed that wall weight alleviates, can play the effect of insulation and assurance strength of wall body again.

Embodiment

Be the short-term strength cement of 15 % with weight ratio, 60% gypsum, 0.15% particle diameter are 3-5 millimeter expansion polyphenyl particle, and 23% sand and all the other are additive, mix stirring, be transported to add water behind the job site and stir after, can use.

Claims (1)

1. the rapid solidification slurry is built in an on-the-spot spray, comprises cement, gypsum, expansion polyphenyl particle, sand, additive; The ratio of each component is according to strength of wall body, and the requirement of indexs such as water tolerance is adjusted, and it is characterized in that: the gypsum weight ratio of its integral part is 40%-54%, 56%-78%, and cement adopts short-term strength cement, the particle diameter 3-5 millimeter of expansion polystyrene.
