Abstract

The invention discloses a waterproof sealant for a bathroom. The waterproof sealant comprises the following components in parts by weight: 23 to 32 parts of polypropylene carbonate type polyurethane elastomer, 15 to 23 parts of polyglycol propylene glycol diol adipate, 2 to 4 parts of an initiator, 3 to 5 parts of beta-cyclodextrin, 1 to 3 parts of a crosslinking agent, 11 to 18 parts of 1,4-phenylene diisocyanate, 5 to 8 parts of inorganic filler and 8 to 12 parts of dimethyl methylphosphate. The waterproof sealant is resistant to medium erosion, and the long-term stability of a sealing effect can be ensured.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a waterproof sealant for toilets. Background technique [0002] A sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion, also known as sealant. Based on polymer materials, it is a material with good sealing effect to prevent the intrusion of external impurities and the leakage of internal media in various mechanical static joints. Divided into bonded and non-bonded two categories. Adhesive type is further divided into elastic type, hot melt type and anaerobic type, etc.; It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Widely used in the sealing of chemical industry, machinery, construction, transportation, electronic instruments and parts. [0003] However, the sealants currently used in toilets cannot ensure long-term stability of the sealing effect in ...
