Embodiment

[0024] A kind of adhesive glue for polystyrene board, described adhesive glue is made up of A component and B component, when described adhesive glue is used, the mass ratio range of A component and B component is 9 ~14:1; by mass percentage, the composition and content of component A and component B in the adhesive are as follows:

[0025] A component

[0026]

[0027]

[0028] B component

[0029] Methanol 10%

[0030] p-toluene sulfuric acid 40%

[0031] Phosphoric acid 50%;

[0032] Wherein, the B component is the reactive curing agent of the A component.

[0033] A preparation method for adhesive glue for polystyrene boards, said preparation method includes the preparation methods of component A and component B respectively, wherein the preparation method of component A is as follows: preheating the reactor, waiting for the reactor After the temperature in the reactor reaches 50-60 degrees, add 63% liquid phenol and 1.2% caustic soda solution into the reactor; ...

Abstract

The invention discloses a binding glue for a polyphenyl plate. The binding glue consists of components A and B; when the binding glue is in use, the mass ratio of the component A to the component B is within a range from (9 to 14) to 1; the component A comprises the following ingredients in percentage by weight: 63% of phenol, 25% of formaldehyde, 1.2% of catalyst, 1.2% of caustic soda solution, 6.3% of water, 1.8% of emulsification agent and 0.8% of foaming agent; the component B is a reaction hardening agent of the component A. A preparation method of the binding glue comprises a component A preparation method and a component B preparation method. The bonding glue has the advantages of high hardening speed, large foaming size, firmness in bonding, no odor, low aging and pulverization possibility, stable structure, good waterproof property, environmental friendliness, energy conservation and the like; the preparation method provided by the invention is simple and easy.

Description

technical field [0001] The invention relates to an adhesive glue and a preparation method thereof, in particular to an adhesive glue used for polystyrene boards and a preparation method thereof. Background technique [0002] Building energy conservation will be a key point in the development of China's construction industry in the 21st century. The current building energy consumption is huge, and the waste is seriously inconsistent with my country's current development goals. my country is a big energy-consuming country. The heating energy consumption per unit building area is about three times that of developed countries with similar climates. Building energy consumption has exceeded a quarter of the country's total energy consumption, ranking first in the country's energy consumption ratio. For this reason, the country has formulated the basic principle of "conserving energy and realizing sustainable development". [0003] Compared with other building energy-saving techno...
