Embodiment 1

[0012] A door and window sealing and waterproof material, which is composed of the following raw materials in parts by weight: calcium carbonate 70, three-line dewaxed oil 10, clay 10, castor oil 1.8, rosin 2.5, lead red 4, petroleum ether 2.4, dicumyl peroxide Joint agent 5, tetrabromoethane 0.8; the specific preparation method of the sealing and waterproof material is to mix the calcium carbonate, three-line dewaxed oil, clay, castor oil, and rosin in the above parts by weight at a temperature of 180°C and 1.35MPa at a rate of 550r / min. Stir at a rotating speed for 3.5 hours to prepare the mixed main material. Put the mixed main material and all remaining raw materials into a centrifugal mixer for centrifugal mixing. The temperature of the centrifugal mixer is kept at 230 ° C. After cooling, it is uniformly dispersed to form a finished product.

Embodiment 2

[0014] A door and window sealing and waterproof material, which is composed of the following raw materials in parts by weight: calcium carbonate 80, three-line dewaxed oil 15, clay 12, castor oil 2.0, rosin 2.7, lead red 5, petroleum ether 2.6, dicumyl peroxide Joint agent 6, tetrabromoethane 1.2; the specific preparation method of the sealing and waterproof material is to mix the calcium carbonate, three-line dewaxed oil, clay, castor oil, and rosin in the above-mentioned parts by weight at a temperature of 180°C and a condition of 1.35MPa at a rate of 550r / min. Stir at a rotating speed for 3.5 hours to prepare the mixed main material. Put the mixed main material and all remaining raw materials into a centrifugal mixer for centrifugal mixing. The temperature of the centrifugal mixer is kept at 230 ° C. After cooling, it is uniformly dispersed to form a finished product.

Abstract

The invention discloses a door and window sealing waterproof material. The door and window sealing waterproof material comprises the following raw materials in parts by weight: 70-80 parts of calciumcarbonate, 10-15 parts of three-line dewaxed oil, 10-12 parts of clay, 1.8-2.0 parts of castor oil, 2.5-2.7 parts of rosin, 4-5 parts of red lead, 2.4-2.6 parts of petroleum ether, 5-6 parts of a dicumyl peroxide cross-linking agent, and 0.8-1.2 parts of tetrabromoethane. A preparation method of the waterproof material comprises the following steps: stirring calcium carbonate, the three-line dewaxed oil, clay, castor oil and rosin according to the above weight parts at the temperature of 150-200 DEG C and pressure being 1.2-1.5 MPa for 3-4 h at a rotating speed of 500-600 r / min, preparing a mixed main material, placing the mixed main material and residual raw materials in a centrifugation mixer for centrifugation stirring, wherein the temperature of the centrifugation mixer is kept at 200-260 DEG C, cooling the materials and uniformly dispersing the material to obtain the finished product. The door and window sealing waterproof material combines sealing performance and waterproofness,has the advantages of strong anti-compression capability, long usage life, and better high temperature resistance, can effectively avoid easy oxidation of the door and window sealing waterproof material, and can form integral sealing.

Description

technical field [0001] The invention relates to the field of waterproof sealing, and specifically belongs to a door and window sealing waterproof material. Background technique [0002] At present, the waterproofing of doors and windows of various buildings is a key issue. Commonly used waterproof materials are various types of waterproof membranes, waterproof coatings, waterproof cement, etc. Waterproof membranes are generally hot construction, mostly baked by fire, the main disadvantage is that the bonding is not comprehensive, there are seams, and some special parts, such as corners, nozzles, etc. Not easy to repair. Waterproof coatings are usually applied cold. After the waterproof coating is mixed well, it can be painted at one time. There is no joint construction and strong adhesion. Its shortcomings are that its strength is not high, and its self-protection is not strong; and the function of this waterproof material is relatively single, which directly affects th...
