Embodiment 1

[0009] Embodiment 1, the present invention adopts polystyrene plastic foam to make aggregate, it is pulverized into granule, then fully stirs with cement and water, wherein, aggregate 4%, cement 35%, all the other are water, form mixture after stirring , then add additives, the mass ratio of mixture and additives is 270:0.8, the additives are composed of foaming agent, foam stabilizer, foam control agent, wherein, foaming agent, foam control agent, foam stabilizer are respectively used Aluminum powder, alkali solution, sodium silicate. Among them, the ratio of the three additives, aluminum powder: alkali solution: sodium water glass is 0.2: 0.3: 0.4; finally cast into shape. In addition to production in the processing room, it can also be poured on the construction site.

Embodiment 2

[0010] Embodiment 2. The present invention adopts polyurethane foam as aggregate, which is pulverized into granules, and fully stirred with cement and water. The cement is ordinary Portland cement. Among them, 5% of aggregate, 45% of cement, and the rest are water. After stirring, it will form a mixture, and then add additives. The mass ratio of mixture to additives is 300:1. The additives are composed of foaming agent, foam stabilizer, Foam control agent composition, wherein, foaming agent, foam control agent, foam stabilizer in auxiliary agent adopt rosin liquid, oleic acid soap liquid, animal glue liquid; Wherein, three kinds of auxiliary agent ratios, rosin liquid: oleic acid soap liquid: The ratio of animal glue is 0.3:0.5:0.7; finally, it is poured into shape. In addition to production in the processing room, it can also be poured on the construction site.

Embodiment 3

[0011] Embodiment 3, the present invention adopts polyvinyl chloride foam to make aggregate, it is pulverized into granule, then fully stirs with cement and water, wherein, aggregate 6%, cement 45%, all the other are water, become mixture after stirring, Add auxiliary agent again, mixture and auxiliary agent mass ratio are 350: 1.5, auxiliary agent is made up of foaming agent, foam stabilizer, foam control agent, wherein, foaming agent is soap foam, and foam control agent is triethanolamine, The foam stabilizer adopts borax; wherein, the ratio of the three additives is soap bubbles: borax: triethanolamine 0.3: 0.2: 0.3; and finally pouring into shape. In addition to production in the processing room, it can also be poured on the construction site.

Abstract

A preparation method of heat-insulating material includes the following steps: using one kind of three chemical raw materials of polystyrene foam, polyurethane foam and polyvinyl chloride foam as aggregate, pulverizing it into granules, mixing it with cement and water and fully stirring to obtain a mixture material, adding adjuvant, the mass ratio of mixture material and adjuvant is 250-350:0.5-1.5, and the adjuvant is formed from foaming agent, foam-stabilizer and foam-controlling agent, finally pouring and forming. The said invention possesses the advantages of light weight and good heat-insulating effect. The main performance indexes of the said invented product are as follows: folume weight 285-495 kg/m3 28d compressive strength 0.5-4.8 mpa, thermal conductivity coefficient 0.082-0.12W/C (m.k) and freezing-thawing resistance at -15 deg.C - -20 deg.C for 25 times shows that its sample is intact.

Description

Technical field [0001] The invention relates to a thermal insulation material and a preparation method thereof. Background technique [0002] The treatment of industrial waste has always been a difficult problem for people. For example, polystyrene foam in factories or daily life is often difficult to deal with. It is usually buried deep in the ground, but it is extremely difficult to degrade and seriously pollutes the environment. Although there are some processes Methods to deal with these industrial or civil wastes, but the process is more complex, and the treatment effect is still not ideal, it is difficult to meet the needs of production and life. In the construction industry, a large amount of building materials are required all the year round, especially materials with good thermal insulation effects are in greater demand, while the existing common building materials have poor thermal insulation effects. Contents of the invention [0003] The object of the present ...
