Method for preparing packing and sealing fireproof adhesive

Abstract

The invention discloses a method for preparing a packing and sealing fireproof adhesive. The packing and sealing fireproof adhesive is prepared by mixing 45 to 80 weight percent of waterproof expansion adhesive and 20 to 55 weight percent of expansion fire retardant. In the invention, the adhesive which expands upon contact with water and fire-retarding material which expands upon contact with fire are mixed, so the packing and sealing fireproof adhesive has both sealing and waterproof performance and fire-retarding and fireproof functions; and thus, the conventional packing agent for buildings, which has a single waterproof function, is improved.

Description

technical field [0001] The invention relates to a preparation method of a caulking and sealing fireproof adhesive. The colloid not only has the performance of sealing and waterproofing, but also has the function of preventing fire and preventing fire, which improves the simple waterproof caulking agent used in existing buildings. Background technique [0002] As an indispensable material for construction and road traffic, waterproof filler is closely related to people's daily life. The existing waterproof materials, especially waterproof sealants, are gradually developing in the direction of water absorption and expansion. China Construction Herald discloses a water absorption expansion The water-swellable rubber made of resin has excellent water-swellability and no precipitates when it meets water, which can effectively prevent water seepage and water leakage in the filled gaps, but these materials do not have the function of fire prevention.

[0002] As an indispensable material for construction and road traffic, waterproof filler is closely related to people's daily life. The existing waterproof materials, especially waterproof sealants, are gradually developing in the direction of water absorption and expansion. China Construction Herald discloses a water absorption expansion The water-swellable rubber made of resin has excellent water-swellability and no precipitates when it meets water, which can effectively prevent water seepage and water leakage in the filled gaps, but these materials do not have the function of fire prevention. All materials have air permeability. Therefore, when a fire occurs, hot smoke will pass through the air-permeable pores of the waterproof material in these gaps to the adjacent area, causing the fire to spread. At the same time, in various existing building structures, various Gaps such as expansion joints, settlement joints, and interface joints are also weak links in fire prevention. When a fire breaks out, smoke and fire can easily escape from these gaps into adjacent buildings, causing the fire to spread. The requirements are getting higher and higher, and the fire prevention of building gaps is particularly important.
