Embodiment 1

[0048] Example 1: Preparation of thermal insulation, light weight, thick boards and profiles.

[0049] Its steps and process conditions are as follows:

[0050] Step 1: Diffusion and Mixing

[0051] In a 45-liter sealed pressurizer, add 25 kilograms of waste polystyrene plastic (PS) (previously crushed into millimeter segments and granules), add 0.001 kilogram of epoxy silicate, 0.01 kilogram of talcum powder and CO 2 1.5 kg, at room temperature 25°C±2°C, pressurize 6-9MPa, diffuse statically for 2 hours, or stir dynamically for 0.5 hour.

[0052] Step 2: Reaction and pre-expansion.

[0053] The mixed materials mixed in the first step are input into the heating reaction pre-expander, and the temperature is maintained at 90-95°C. The equipment can be installed in a general-purpose cylinder with a diameter of 650-700mm and a height of 1100mm. The production capacity is 35-85 kg / hour. If steam heating is used to control the steam pressure: 0.190Mpa, electric heating can be use...

Embodiment 2

[0065] Example 2: Preparation of interior and exterior wall insulation, radiant heating insulation layer, and color metal plate sandwich layer

[0066] step one:

[0067] 25.5 kg of waste PS, 0.01 kg of epoxy silicate, 0.03 kg of acrylic acid, 1 kg of waste polyethylene or waste polypropylene, 0.01 kg of dicumyl peroxide (DCP), CO 2 Put 2 kg into a 45 liter pressure sealer, pressurize at 6.5-10.0 MPa, stir for 0.3-1 hour, heat up to 120°C for 10 minutes, and cool to room temperature.

[0068] Step two:

[0069] Add the mixture of step 1 to the high-speed mixer, add 0.0-0.4g / 100g liquid paraffin, 0.3-0.5g / 100g citric acid, 0.3-0.5g / 100g sodium hydrogen phosphate, mix for 10 minutes and then input into ordinary extrusion machine. Extrude the insulation layer with a thickness of less than 30mm. The surface can be pasted with ordinary building adhesives on the inner and outer walls of the concrete and the radiant heating insulation layer under the floor. The color steel and col...

Embodiment 3

[0073] Example 3: Preparation of lightweight polymer building materials

[0074] step one:

[0075] After drying the white mud (slag mainly containing kaolin and mica, with a particle size of 80 microns to 20 microns) at 60°C, weigh 25 kg of dry white mud, add 0.01 kg of epoxy silicate, 0.02 kg of acrylic acid, silicon Sodium acid (Na2SiO3) 1.00 kg, sodium hydroxide 1.0 kg, water (neutral) 0.5 kg, CO 2 Add 12.5 kg into a 45-liter pressure sealer, pressurize at 6.5-10 MPa, stir for half an hour, heat up to 40-90°C for 10 minutes, and cool to room temperature.

[0076] Step two:

[0077] Pour the mixture in step 1 into the prefabricated molds such as boards, walls, special shapes, etc., which can be used as hollow outer walls, solid inner columns, board core materials, etc.

[0078] Step three:

[0079] Add the mixture of step 1 in example 1 to the hollow outer wall or inner column of step 2 in this example, and use the suction input method to keep the gaps in the irregular ...

Abstract

The present invention provides process of producing high performance nanometer composite material with waste and CO2 as main material and medium. The high performance nanometer composite material is produced with organosilicon compound, aliphatic acrylic acid and its ester derivative and / or oligomer as monomer material, CO2 as medium, inorganic waste and organic waste, and through diffusion, mixing, reaction, etc. The high performance nanometer composite material may be used widely in different fields, and the used product may be recovered for reuse.

Description

technical field [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a method for using waste materials and CO 2 Methods of producing nanocomposites. technical background [0002] Polymer nanocomposites have shown advantages in the functional and structural applications of many materials. There are many reports on the production of nanocomposites, such as Chinese invention patent ZL 98104787.4; ZL 96108338; US patent USP5369147 (1994); USP 5650106(1997) USP 5866053(1999); USP 6069183(2000); USP 6583188(2003). However, the proportion of materials produced by these patented technologies will increase, which will increase the energy consumption of logistics and transportation. [0003] In order to reduce the specific gravity (density) of materials and give full play to the functional advantages of materials in mechanics, heat insulation, sound absorption, shock absorption insulation, absorption, separation and selection, ...
