Embodiment Construction

[0011] In order to further illustrate the present invention, the present invention will be further described in detail below in conjunction with specific examples.

[0012] The first step is to mix the adhesive and the inorganic powder according to the ratio of 1:1.5~2 evenly, and press the mixture with the non-woven fabric with a professional production line to make a 0.1mm~5mm fire-resistant, waterproof, high-strength polymer Cement sheet spare.

[0013] The adhesive is made of the following raw materials according to the weight ratio: 75-85% of polymer emulsion, 5-10% of flame retardant, 1-6% of film-forming aid, 5-10% of deionized water, thickener Agent 0-1.5%.

[0014] For example:

[0015] ①. Weigh 75% of high molecular polymer emulsion, 10% of flame retardant, 6% of film-forming aid, and 9% of deionized water by weight percentage, put them into a stirrer, and stir evenly to prepare the adhesive.

[0016] ②. Weigh 85% of high molecular polymer emulsion, 5% of flame re...

Abstract

The invention discloses a preparation method of modified phenolic foam composite insulation board. In the method, water resistance and flame resistance polymer cement sheet is prepared in advance andthe method is characterized in that a phenolic foaming machine continuous production line is adopted to foam the foaming raw material to modified phenolic foam composite insulation sheet while the water resistance and flame resistance polymer cement sheet is combined to the both sides of the modified phenolic foam composite insulation sheet. The foaming raw material comprises the following raw materials by weight percent: 60-80% of phenolic resin, 3-6% of foaming agent, 3-7% of polyurethane modifier, 12-32% of catalyst and 1-3% of foam stabilizer. The composite board prepared in the inventionhas excellent flame resistance and good water resistance and heat preservation effect; in addition, the insulation core material has high strength and toughness and does not drop residue so as to completely meet the national requirements of building engineering in energy-saving, water resistance, heat preservation, flame resistance and the like and be widely used for the large area heat preservation, flame resistance and water resistance inside and outside the external walls of building.

Description

technical field [0001] The invention relates to a method for manufacturing a thermal insulation composite board for building exterior walls, in particular to a method for manufacturing a modified phenolic foam composite thermal insulation board Background technique [0002] Existing thermal insulation composite boards used in exterior walls of buildings, such as EPS, XPS, and PU foam thermal insulation composite boards, have the best flame-retardant grades and can only reach flame-retardant B2 grades. With the improvement of the country's energy-saving requirements for construction projects and the promulgation of corresponding fire protection regulations, these thermal insulation composite panels made of foam plastics for traditional thermal insulation have low combustion levels, high smoke density and poisonous smoke when they are on fire, and are used in external walls of buildings. The above will be restricted, especially in the thermal insulation project of the building...
