Abstract
The invention relates to a gypsum-based floor thermal insulation material. The material is characterized in comprising the following raw materials, by weight: 65-70 parts of gypsum, 8-12 parts of vitrified micro beads, 10-15 parts of quartz sand, 8-12 parts of heavy calcium powder, 0-4 parts of light calcium powder, 1.3-2.6 parts of redispersible latex powder, 0.38-0.48 parts of a water reducing agent, 0.02-0.03 parts of a water retaining agent, and 0.1-0.13 parts of a retarder. The gypsum-based floor thermal insulation material provided by the invention has the advantages of good fluidity, excellent thermal insulation performance, high coagulation and hardening speed, no bleeding and segregation, no shrinkage, no hollowing and cracking phenomena, and the like. The material can be used as a bed layer or an intermediate layer of a floor material.
Description
Technical field
The invention belongs to lagging material, specifically a kind of gypsum base terrace lagging material.
Background technology
Along with the deterioration of global environment and the impact of energy dilemma increasingly sharpen, the consciousness of people to energy-saving and environmental protection grows with each passing day, and government department has also put into effect corresponding strict building energy-saving standard in succession, makes energy saving building material become the key subjects of research.
The annual quantity discharged of China's industry by-product gypsum reaches more than hundred million tons; outside most industry by-product gypsum is stacked in throughout the year; take a large amount of soils; pollute surrounding enviroment; industry by-product gypsum is utilized to prepare β-semi-hydrated gypsum and the alpha-semi water plaster stone with gelling property; both the protection of environment had been conducive to, again can save energy and resource, meet National Sustainable Development Strategies.
People to work and living environment requirement along with expanding economy more and more higher, summer using air-condition cooling, winter using air-condition, floor heating heat up.Existing common building lagging material is used for body of wall, therefore still has considerable heat to be spread out of by floor, adds energy consumption, and existing thermal insulation mortar needs manually floating, takes time and effort.
Invent the ground heat insulating material with certain fluidity that a kind of β of utilization-semi-hydrated gypsum or alpha-semi water plaster stone are major gelled material in view of the foregoing, heat can be prevented to scatter and disappear from floor, and without the need to manually floating, only need shakeout gently, time saving and energy saving.
Summary of the invention
The object of the invention is to propose a kind of gypsum base terrace lagging material to improve the deficiencies in the prior art.
Technical scheme of the present invention for: it is characterized in that shared by its feed composition and each component, weight part is as follows: 65 ~ 70 parts of gypsum, 8 ~ 12 parts of glass beads, 10 ~ 15 parts of quartz sands, 8 ~ 12 parts of dicalcium powders, 0 ~ 4 part of light calcium carbonate powder, 1.3 ~ 2.6 parts of redispersable latex powders, 0.38 ~ 0.48 part of water reducer, 0.02 ~ 0.03 part of water-holding agent, 0.1 ~ 0.13 part of retardant, water material mass ratio is 0.40 ~ 0.50.
Preferably above-mentioned gypsum is the one in β-semi-hydrated gypsum or alpha-semi water plaster stone.
The median size of preferably above-mentioned glass bead is 1-2mm, unit weight 95-150kg/m
3.
Preferably described quartz sand is 40 ~ 60 orders and 60 ~ 120 object quartz sand 1:(1.8 ~ 2.2 in mass ratio) used in combination.
The order number of preferably described dicalcium powder is 400 orders.The order number of preferably described light calcium carbonate powder is 1250 orders.
Preferably described can point latex powder be " Wa Ke " again
(VAE), " Wa Ke "
one in (VAE); Water reducer is the one in PC-1016 type poly carboxylic acid powder water reducer or HY type poly carboxylic acid powder water reducer; Water-holding agent is hydroxypropyl methyl cellulose ether (HPMC), range of viscosities 60000 ~ 100000mpa.s; Retardant is the one in SG-10 calcium sulphate retarder or trisodium citrate.
Present invention also offers the preparation method of above-mentioned gypsum base terrace lagging material, take gypsum as major gelled material, glass bead is light skeletal, adds filler, quartz sand and admixture, above-mentioned each raw material stirring is mixed and make.In use, be 0.40 ~ 0.50 gypsum base terrace lagging material is added to the water stirs according to water material mass ratio.
Beneficial effect:
The glass bead that the present invention uses has light weight, advantage that surperficial vitreous rate is high, is combined, can not only keeps the characteristic that gypsum is intrinsic with semi-hydrated gypsum, can improve again that material is anti-aging, weathering resistance, fire prevention and resistance to cleavage.Thus compensate for that pearlstone water-intake rate is large, surface easily produces hollowing, cracking phenomena, granular polystyrene fire line is poor, the shortcoming that can produce obnoxious flavour and loss of properties on aging when chance high temperature.Therefore gypsum base terrace lagging material good fluidity; There are enough operable times; Moderate strength, high insulating effect; Stability is high, without segregation and excreting water phenomenon; Setting and harden speed is fast.
