Embodiment 1

[0032] In this embodiment, the high weather resistance silicone waterproof gasket consists of the following components by weight:

[0033]

[0034] The preparation method of the above-mentioned high weather resistance silicone waterproof gasket is as follows: first mix the silicone rubber with processing aids such as anti-aging agent, accelerator, white carbon black and high-efficiency dispersion reinforcing agent, and then add a vulcanizing agent to carry out cross-linking vulcanization , forming a silicone rubber with a certain degree of crosslinking. Then add an internal release agent, and carry out a molding process under high temperature and high pressure through a mold to make a waterproof gasket. The molding temperature of the mold was 150°C.

Embodiment 2

[0036] In this embodiment, the high weather resistance silicone waterproof gasket consists of the following components by weight:

[0037]

[0038] The preparation method of the above-mentioned high weather resistance silicone waterproof gasket is as follows: first mix the silicone rubber with processing aids such as anti-aging agent, accelerator, white carbon black and high-efficiency dispersion reinforcing agent, and then add a vulcanizing agent to carry out cross-linking vulcanization , forming a silicone rubber with a certain degree of crosslinking. Then add an internal release agent, and carry out a molding process under high temperature and high pressure through a mold to make a waterproof gasket. The molding temperature of the mold was 200°C.

Embodiment 3

[0040] In this embodiment, the high weather resistance silicone waterproof gasket consists of the following components by weight:

[0041]

[0042] The preparation method of the above-mentioned high weather resistance silicone waterproof gasket is as follows: first mix the silicone rubber with processing aids such as anti-aging agent, accelerator, white carbon black and high-efficiency dispersion reinforcing agent, and then add a vulcanizing agent to carry out cross-linking vulcanization , forming a silicone rubber with a certain degree of crosslinking. Then add an internal release agent, and carry out a molding process under high temperature and high pressure through a mold to make a waterproof gasket. The molding temperature of the mold was 170°C.

[0043] The high weather resistance silicone waterproof gasket and its preparation method provided by the invention, compared with the traditional rubber gasket, this product has excellent strength, elongation at break, resili...

Abstract

A highly weather-resistant silicone waterproof gasket and a manufacturing method thereof. The highly weather-resistant silicone waterproof gasket of the present invention consists of the following components by weight: silicone rubber: 70-90 parts, anti-aging agent: 0.5-1.5 parts, accelerator: 0.5-2 parts, internal mold release agent: 1 -5 parts, white carbon black: 3-15 parts, high-efficiency dispersion reinforcing agent: 3-5 parts, vulcanizing agent: 1-7.5 parts. The manufacturing method is as follows: first mix the silicone rubber with processing aids; then add a vulcanizing agent for cross-linking and vulcanization to form vulcanized silicone rubber; A molding process is carried out to obtain the high weather resistance silicone waterproof gasket. The prepared product has excellent strength, elongation at break, resilience and tightness, and can effectively solve the leakage problem existing in the current large-scale steel structure roof while reducing the engineering cost.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a highly weather-resistant silicone waterproof gasket and a manufacturing method thereof. Background technique [0002] Steel structure roofs have been widely used in general industrial and agricultural, commercial and service buildings. As an indispensable and important part of housing construction projects, steel structure roofs are usually composed of three parts: Safe use, the comfort of people's living environment and building energy efficiency have a great relationship. However, with the rapid development of such projects, roof leakage has also occurred one after another. Construction companies are mostly troubled by the waterproofing of metal roofs of light steel structure buildings. [0003] At present, the leakage of most steel structure roofs in my country is relatively serious, and this phenomenon is more prominent in the southern region, especially in areas wit...
