Abstract
The technical scheme of the invention is as follows: adhesive mortar powder for an STP heat-insulation panel. The adhesive mortar powder is characterized by being prepared from the following components in parts by weight: 30-40 parts of low-alkalinity sulphate aluminum cement, 50-60 parts of quartz sand, 10 parts of ground calcium carbonate, 0.15 part of methylcellulose ether, 3-3.5 parts of redispersible latex powder, 0.1-0.2 part of a naphthalene water reducer and 0.1-0.2 part of a retarder. The adhesive mortar powder provided by the invention has the beneficial effects that according to the technical scheme, the low-alkalinity sulphate aluminum cement is adopted, and the hydrated liquid of the cement is relatively low in alkalinity, so that the corrosion to the heat-insulation panel can be effectively reduced and the heat-insulation performance is ensured. Since two types of quartz sand which are different in particle size (meshes) are mixed, the grading of the quartz sand is improved and the thickness and porosity of the adhesive mortar are reduced. By adopting 100,000 Pa.s of methylcellulose ether, the viscosity and water-retaining property of the adhesive mortar can be ensured and the cost is lowered.
Description
Technical field
The present invention relates to composite dry powder mortar material field, relate in particular to the adhesive mortar powder that a kind of ultra-thin adiabatic STP warming plate is used.
Background technology
STP ultrathin heat insulation board is a kind of novel, energy-efficient building thermal insulation material, and it has higher thermal resistance coefficient, higher fire-protection rating, is more and more applied to external wall as lagging material.STP ultrathin heat insulation board outermost layer is glass fibre, be commonly called as glass wool, glass fibre is not alkaline-resisting, if do adhesive mortar with common silicate cement, it is glass fibre that the alkali lye producing in the time of hydrated cementitious can corrode STP ultrathin heat insulation board outermost layer, causes STP plate to come off.The present invention overcomes the alkalescence of traditional adhesive mortar silicate cement used, adopts low alkali aluminosulfate cement to do base material.
Summary of the invention
The object of this invention is to provide a kind of STP heat insulating thermal preserving board adhesive mortar powder, to overcome adhesive mortar viscosity deficiency of the prior art bonding surface extruded polystyrene board Paint Gloss.
In order to achieve the above object, technical scheme of the present invention is as follows:
A kind of STP heat insulating thermal preserving board adhesive mortar powder, is characterized in that: the component that comprises following parts by weight: 30～40 parts of low-alkalinity sulphoaluminate cements, 50～60 parts of quartz sands, 10 parts of water-ground limestones, 0.15 part of methyl cellulose ether, 3～3.5 parts of redispersable latex powders, 0.1～0.2 part of naphthalene water reducer, 0.1～0.2 part of retardant.
Further, described quartz sand is that 40～70 order sand and 70～120 order sand proportionings are 2:1.
Further, described water-ground limestone powder particle diameter is less than or equal to 0.08mm.
Further, described methyl cellulose ether viscosity is 100000Pas.
Further, preferred Mace 6070 rubber powders of described redispersable latex powder.
Beneficial effect of the present invention is: technical solution of the present invention adopts low-alkalinity sulphoaluminate cement, and this hydrated cementitious liquid caustic soda degree is lower, can effectively reduce the corrosion to warming plate, ensures heat-insulating property.Adopt the quartz sand of two kinds of different meshes to mix use, improved the grating of quartz sand, reduced thickness and the porosity of adhesive mortar.Select the methyl cellulose ether of 100,000 Pas, both ensured viscosity and the water retention property of adhesive mortar, saved again cost.
