Problems solved by technology

[0007] The foam cement and polyurethane insulation materials used in the above patents to prepare wall insulation boards have not effectively solved the problem that the current insulation board strength and insulation effect cannot be balanced. Compared with phenolic resin foam cement insulation boards, the technical means adopted in the above patents The prepared insulation board has good insulation effect, but the strength is low or the insulation effect is low with high strength, which is difficult to meet the demand

Abstract

The invention provides a foamed plastic composite cement insulation board and a preparation method thereof. The invention is characterized in that a porous cement board with the porosity thereof to be40-80% is used as a matrix. The foamed plastic is fully inlaid in pores in the porous cement board. The average pore diameter of the porous cement board is 1-3 mm, and the hole opening rate of the porous cement board is larger than 90%. The density of the porous cement board is 100 kg/m<3>-300 kg/m<3>. The foamed plastic is urea melamine-modified phenolic foamed plastic. The volume ratio of the porous cement board to the foamed plastic is 1-4:1. The pore diameter of the foamed plastic is 8-500 microns and the hole closing rate thereof is greater than 85%. The preparation method of the foamedplastic composite cement insulation board comprises the following steps: removing ash from the surface of the porous cement board, injecting the phenolic resin into the porous cement board, placing the porous cement board into a mold for microwave foaming, taking out the foamed porous cement board from the mold, and removing excessive foams on the surface of the porous cement board. According to the invention, the modified phenolic foam plastic is combined with the porous cement board to achieve the performances of good heat preservation effect and high strength.

Description

technical field [0001] The invention relates to a foam cement insulation board, in particular to a phenolic foam plastic composite cement insulation board and a preparation method thereof. Background technique [0002] At present, with the rapid growth of my country's national economy, the problem of energy shortage is becoming more and more serious. Energy saving work has become an important guarantee for sustainable development, among which the importance of building thermal insulation and energy saving is becoming more and more prominent. With the continuous acceleration of the industrialization process in various countries, energy consumption is getting higher and higher. The world's energy demand is increasing at a rate of 2% per year, and these About 30% of energy is consumed in buildings. In my country, the building energy consumption together with the production energy consumption of enclosure structure materials has accounted for 27.6% of the total energy consumpti...
