Abstract
The invention relates to a fast-hardening-type bonding mortar for an exterior-wall insulation. The mortar is mainly composed of cement, sierozem powder, sand, silica fume and hydroxypropyl methyl cellulose ether. The fast-hardening-type bonding mortar for the exterior-wall insulation can improve workability and water retention of the mortar, increase insulation efficiency, and overcome flaking, cracking and other common problems; and has effects of frost resistance, water reduction, seepage resistance, duration, crack resistance, and heat insulation after hardening.
Description
Technical field
The present invention relates to a kind of fast gravity die exterior-wall heat insulation adhesive mortar, belong to the construction project field.
Background technology
Thermal insulation mortar be with some heat-insulating property preferably material be that aggregate, gelling material, auxiliary agent and water etc. cooperate the mortar of making that is used for the body of wall thermal insulation by a certain percentage, traditional thermal insulation mortar is to be aggregate with the pearlstone, because of the pearlstone water-intake rate very high, fragility is big, cohesive strength is low, resistance to cleavage is poor, uses to be subjected to great limitation.
In recent years; strengthen day by day along with process of urbanization and to the concern of environment protection; on building engineering construction; the on-the-spot masonry mortar that stirs just progressively turns to dry-mixed mortar and premixing mortar to become inexorable trend; simultaneously; along with concrete segment and all kinds of wallboards quote in a large number and impervious to exterior wall; the raising of demand of anti-crack; to mortar performance; particularly cohesive strength and resistance to cleavage are all had higher requirement; and; building energy conservation is also more and more paid attention to; upgrading to the thermal insulation mortar technology is imperative with the replacement; based on the EPS heat insulation property; stability; the characteristics that splitting resistance is good; the present invention replaces pearlstone preparation thermal insulation mortar with the light skeletal of discarded EPS particle; be a kind of innovation to preparation high-performance thermal insulation mortar, to the development of building energy conservation cause and promote the materials for wall reform have certain pushing effect smoothly.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned existing defective, and a kind of fast gravity die exterior-wall heat insulation adhesive mortar is provided, to solve the heat retaining property problem of building mortar.
The present invention is achieved through the following technical solutions, it is characterized in that this fast gravity die exterior-wall heat insulation adhesive mortar mainly by: cement, grey calcium powder, sand, silicon ash, hydroxypropyl methyl cellulose ether etc. are formed.
By its weight ratio be: cement 25～35%; Ash calcium powder 10～20%; Sand 50～60%; Silicon ash 1～3%; Hydroxypropyl methyl cellulose ether 2.5～5.5% is formed.
The fineness of described grey calcium powder is 400 orders; Fineness 30～60 orders of sand.
Embodiment
Take by weighing cement 35% by weight; Ash calcium powder 10%; Sand 50%; Silicon ash 2%; Hydroxypropyl methyl cellulose ether 2.5% is formed.
Add successively in the stirrer by above-mentioned weight ratio, fully mixing and stirring gets final product.
Above-described embodiment, through site operation, fast gravity die exterior-wall heat insulation adhesive mortar of the present invention not only has good working performance, and has good intensity, cohesive strength and anti-contracility energy and weather resistance.
Claims (3)
