Abstract
The invention discloses an expanded and vitrified bead thermal insulation mortar. The expanded and vitrified bead thermal insulation mortar comprises, by weight, 130-150 parts of cement, 30-40 parts of silicon powder, 90-110 parts of expanded and vitrified bead, 8-10 parts of glass fiber, 8-10 parts of latex powder and 1.5-3 parts of cellulose ether. The expanded and vitrified bead thermal insulation mortar has the advantages of good tensile strength, large heat insulation performance, good fireproof performance and the like.
Description
Technical field
The present invention relates to a kind of expansion vitrification bead heat-preserving mortar, belong to building material field.
Background technology
Expansion vitrification bead heat-preserving mortar is formed by material mixing such as expanded and vitrified small ball, cement, fortifying fibre and additives.Wherein expanded and vitrified small ball is, expansion softening under certain temperature condition by the acidic glass matter volcanics of specific composition, and melting vitreous at high operating temperatures, the lightweight spheroidal particle of the class vacuum structure of formation surface-closed, internal porous.The lightweight of expanded and vitrified small ball uniqueness, fire prevention, thermal and insulating performance, make expanded and vitrified small ball mortar have excellent heat insulating and fire performance.But existing expansion vitrification bead heat-preserving mortar Shortcomings in tensile strength, ultimate compression strength, weather resistance etc.
summary of the invention
The object of this invention is to provide that a kind of tensile strength is high, ultimate compression strength is large, heat insulation property can better expansion vitrification bead heat-preserving mortar.
Technical scheme of the present invention is:
A kind of expansion vitrification bead heat-preserving mortar, composed as follows with the raw material of parts by weight: cement 130 weight part-150 weight part, silica flour 30 weight part-40 weight part, expanded and vitrified small ball 90 weight part-110 weight part, glass fibre 8 weight part-10 weight part, latex powder 8 weight part-10 weight part, ether of cellulose 1.5 weight part-3 weight part.
Described strength of cement grade is greater than 32.5.
Described expanded and vitrified small ball granularity is 0.5mm-1.5mm.
Described glass fibre is roving, and length is 20-25mm.
Described ether of cellulose is the methyl cellulose ether of viscosity more than 50000.
Advantage of the present invention is:
Expansion vitrification bead heat-preserving mortar tensile strength of the present invention is good, reaches more than 0.6MPa; Ultimate compression strength is large, can reach more than 0.8MPa; Thermal and insulating performance is good, and thermal conductivity is less than 0.05; And the performance such as splitting resistance, weather resistance, fire line is all significantly improved.
