Description

A kind of cement insulation board manufacture method being added with foamable phenolic particle
Technical field
What the present invention proposed is the lagging material of building materials field, specifically a kind of cement insulation board manufacture method being added with foamable phenolic particle.
Background technology
At present, along with country is to the attention of building energy conservation, various wall heat insulation material arises at the historic moment.According to the needs of Building Fire Protection, cement foaming insulation board have also been obtained application.But the shortcoming that current cement foaming insulation board exists is: unit weight is large, poor toughness, water-intake rate are high, thermal conductivity is high, cause volume heavy, carrying is easily damaged, uses thickness thick, takes up room large.The advantage of cement board is not burn, and can realize fire prevention.
Foamable phenolic plate have also been obtained application, but intensity is low, paste difficulty, but thermal conductivity is low, good heat insulating, has not incendivity with metope.
Summary of the invention
In order to improve the performance of cement insulation board, the present invention proposes a kind of cement insulation board manufacture method being added with foamable phenolic particle.The method, by adding foamable phenolic particle in cement insulation board, solves and reduces unit weight and thermal conductivity, increases the technical problem of toughness.
The scheme that technical solution problem of the present invention adopts is:
1, foamable phenolic particle preparation:
Phenolic aldehyde body material through foaming is joined in disk sawtooth nodulizer, makes the particle of 0.1 ~ 5 millimeter.As foamable phenolic particle.
2, cementing Stabilizing Materials preparation: add calcium stearate, polyvinyl formal solution in the polyvinyl formal solution of moisture 50%: calcium stearate mixing ratio 1:1, as cementing Stabilizing Materials.
3, base material: add 4 premium on currency in agitator, add cementing Stabilizing Materials 100 milliliters again, sisal hemp short fibre 50 grams, foamable phenolic particle 1 ~ 3 kilogram, start stirrer fully to stir with the stirring velocity of 400 ~ 500 revs/min, then 5 kilograms of No. 500 ordinary Portland cements are added, abundant stirring 1 minute, finally add the aqueous hydrogen peroxide solution 500 milliliters that content is 28%, stir rapidly, when enlarged volume, be released to mould in agitator immediately, after 5 days aquations, cement insulation board initial set, carries out the demoulding.After the demoulding, health 20 days under envrionment temperature is 20 ~ 30 DEG C and the environment of humidity 20% ~ 80%, becomes cement insulation board blank.
4, cut: after blank drying, by microtome, slice thickness is between 3 ~ 10 centimetres, and length is between 30 ~ 60 centimetres, and width, between 30 ~ 45 centimetres, becomes cement insulation board and becomes material.
5, slurry preparation: by quality, be in the water glass solution of 20 at the degree Beaume of 1 part, adding content is 50% polyvinyl formal solution 1 part, then adds the organosilicon aqueous solution 0.1 part, as slurry after stirring.
6, enhancement process: cement insulation board soaked and carry out dipping enhancement process in the slurry, dipping time is 10 minutes, pulls out after dipping, naturally dries or dries, and becomes the cement insulation board that finished product is added with foamable phenolic particle.
Positively effect, the cement insulation board adopting the inventive method to make and the greatest advance of common cement insulation board are: reduce thermal conductivity, add toughness, reduce unit weight, reduce use thickness.Be suitable for applying as the manufacture method of wall insulated board.
Embodiment
1, foamable phenolic particle preparation:
By the phenolic aldehyde body material through foaming, join in disk sawtooth nodulizer, make the particle of 0.1 ~ 5 millimeter.As foamable phenolic particle.
2, cementing Stabilizing Materials preparation: add calcium stearate, polyvinyl formal solution in the polyvinyl formal solution of moisture 50%: calcium stearate ratio 1:1, as cementing Stabilizing Materials.
3, base material: add 4 premium on currency in agitator, add cementing Stabilizing Materials 100 milliliters again, sisal hemp short fibre 50 grams, foamable phenolic particle 1 ~ 3 kilogram, start stirrer fully to stir with the stirring velocity of 400 ~ 500 revs/min, then 5 kilograms of No. 500 ordinary Portland cements are added, abundant stirring 1 minute, finally add the aqueous hydrogen peroxide solution 500 milliliters that content is 28%, stir rapidly, when enlarged volume, be released to mould in agitator immediately, after 5 days aquations, cement insulation board initial set, carries out the demoulding.After the demoulding, health 20 days under envrionment temperature is 20 ~ 30 DEG C and the environment of humidity 20% ~ 80%, becomes cement insulation board blank.
4, cut: after blank drying, by microtome, slice thickness is between 3 ~ 10 centimetres, and length is between 30 ~ 60 centimetres, and width, between 30 ~ 45 centimetres, becomes cement insulation board and becomes material.
5, slurry preparation: by quality, be in the water glass solution of 20 at the degree Beaume of 1 part, adding content is 50% polyvinyl formal solution 1 part, then adds the organosilicon aqueous solution 0.1 part, as slurry after stirring.
6, enhancement process: cement insulation board soaked and carry out dipping enhancement process in the slurry, dipping time is 10 minutes, pulls out after dipping, naturally dries or dries, and becomes the cement insulation board that finished product is added with foamable phenolic particle.
Performance Detection is tested: selection thickness is that the common cement insulation board of 6 centimetres compares, the cement insulation board selecting 6 cm thicks to be added with the foamable phenolic particle of 2 kilograms makes testing inspection, detect through actual, control board thermal conductivity is 0.068, and test board thermal conductivity is 0.04.
Shown by test data, the cement insulation board and the cement insulation board thermal conductivity that are added with foamable phenolic particle reduce 0.028.
According to detection data analysis, foamable phenolic particle adds to greatest extent in cement insulation board, is conducive to the reduction of thermal conductivity, improves heat-insulating property, improves toughness.
Finished product is observed: by carrying out eye-observation to the finished surface made, foamable phenolic even particulate dispersion, between the micropore of cement board, forms the foam structure body of foamable phenolic particle and foam cement continuously.Analyze the formation of its structure, when in heat conduction process, continue through foam cement abscess-foamable phenolic particle-foam cement abscess-foamable phenolic particle, until to the other end, thermal conductivity values is high and low, high and low change, combine the mean value of foam cement and foamable phenolic, overall thermal conductivity is reduced.
Advantage of the present invention:
1, owing to being added with foamable phenolic particle in cement insulation board, so unit weight is low, thermal conductivity is low, good toughness.
2, because cement insulation board becomes material through dipping sizing agent enhancement process, so surface strength is high, do not fall slag, not efflorescence, carrying and use procedure not damaged, and be conducive to pasting with body of wall.
3, owing to being added with cementing Stabilizing Materials in cement insulation board, add the cohesive force between foam cement and foamable phenolic particle, make foamable phenolic particle can firmly and foam cement bond, can not bulk strength be reduced, and can toughness be increased.
4, because foamable phenolic plate cost is high, and thermal conductivity is low, and cement board cost is low, thermal conductivity is high, after with the addition of foamable phenolic particle in cement board, compared with cement insulation board, thermal conductivity reduces, and though cost is improved, but can reduce thickness, the usable floor area of unit volume increases, so the numerical value that cost increases can be accepted, compared with similar products, the market competitiveness is had more.
