Abstract

The invention provides an environment-friendly flame-retardant single-component silane-modified polyether sealant and a preparation method thereof. The sealant is prepared from the following components in parts by mass: 10-40 parts of silane-modified esserbetol, 10-25 parts of a plasticizer, 30-70 parts of flame-retardant filler, 0-20 parts of reinforced filler, 0.1-1 part of a functional accessory ingredient, 0.5-1.5 parts of a dewatering agent and 1-3 parts of a cementation accelerant, wherein the plasticizer is at least one of hexamoll DINCH and polypropylene glycol. The environment-friendly flame-retardant single-component silane-modified polyether sealant provided by the invention does not need addition of a phthalic ester plasticizer, furthermore does not contain heavy metals such as organic tin, is environmentally friendly, and is good in product performance.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant one-component silane-modified polyether sealant and a preparation method thereof. Background technique [0002] There are three types of elastic sealants developed early and widely used in various industrial fields: polysulfide type, silicone type, and polyurethane type, which have played an important role in promoting the development of various fields. However, they each have some defects. Due to its poor durability and resistance to deformation and displacement, polysulfide sealants are easily affected by unstable disulfide chains in the molecule during long-term use, resulting in gradual increase in compression and elongation deformation, and surface Cracks appear; due to poor construction performance of polyurethane sealant, bubbles are easily formed in the adhesive layer during curing, limited bonding performance, poor heat and humidity resistance and aging resistance, short storage ...
