Description

A kind of fire-retardant fireproof partition plate thermal insulation mortar

Technical field

The present invention relates to building material technical field, particularly relate to a kind of fire-retardant fireproof partition plate thermal insulation mortar.

Background technology

Building energy conservation theory has been subjected to the common concern of countries in the world, and the main cause that building energy utilization ratio is low is Heat insulating ability and the seal of building construction building enclosure are poor, cause mass energy to be wasted.To this end, exploitation thermal and insulating performance The construction material good, thermal capacity is big becomes energy-conservation key.In recent years, expanded polystyrene (EPS) thermal insulation mortar is owing to having heat conduction system The advantages such as low, the good weatherability of number, easy construction and become the point of penetration of research China building materials energy-saving material.Light-weight building goes along with sb. to guard him material Material can effectively reduce dead load, it is ensured that the heat preservation and insulation of building, can effectively reduce again transport and plant produced The cost of prefabricated component.Therefore exploitation non-bearing light thermal-insulation dividing plate just comes have good Research Significance and using value. Although existing heat-preservation partition board light weight, but there is also the problem that intensity is low, due to outer layer calcium silicate board mechanical property and In unit are, quality is usually maintained in a specific scope, therefore core body (air entrained concrete is combined with EPS) density, every Hot property and and calcium silicate board between caking property become the key content of research.

In " preparation of light thermal-insulation partition plate and performance study " literary composition author from raw material ratio, screen and optimize realization The high heat preservation performance of EPS slurry, can be seen that the comprcssive strength of the dry apparent density direct relation core body of core body from experimental data With heat-insulating property, in certain circumstances, dry apparent density is the least, and heat conductivity is the lowest for general core body density, and heat-proof quality is more Good, but comprcssive strength is the highest therewith.From article, can be seen that the powder density reducing composition slurry is optimal method.Its Middle flyash has potential chemism, fine particles, and containing a large amount of vitreous body microballons, mixes in dry-mixed mortar and can send out Wave active effect, shape effect and microgranule filling effect, from experimental data, can be seen that with the addition of flyash can make material Comprcssive strength increases, and dry apparent density declines, but is as the raising of fly-ash-contained ratio, cement cementitious material ratio Example also relative drop, causes the comprcssive strength of material progressively to decline.This present invention is proposed adds coal ash fiber and substitutes fine coal Ash play in mortar heat insulation, be incubated, improve the effect of comprcssive strength.
