Problems solved by technology

[0003] At present, there are still some deficiencies in the existing door and window sealing water blocking materials, for example; The phenomenon of aging or cracking increases the probability of damage to the water-blocking material during use and shortens the service life of the water-blocking material. Moreover, the existing door and window sealing water-blocking materials will not expand after absorbing water, which weakens the water-blocking material. The tightness between water-resistant materials and doors and windows reduces the water-proof effect when water-blocking materials are used

Embodiment 1

[0033] The door and window sealing water-blocking material includes the following raw materials and their weight fractions: 45 parts by mass of butyl rubber; 20 parts by mass of epoxy resin; 25 parts by mass of polyethylene glue; and 2% by mass of antistatic agent; The antioxidant is 3% by mass; the cross-linking agent is 5% by mass.

[0034] The preparation steps are as follows:

[0035] a. Weigh the above-mentioned raw materials according to parts by weight;

[0036] b. After step a is completed, mix the butyl rubber, epoxy resin and polyethylene glue in an internal mixer for mixing to obtain a mixed rubber. The mixing temperature is 100-130°C, and the mixing time is 10- 15min, after mixing, place it in an open mill for heat dissipation;

[0037] c. After step b is completed, add calcium chloride, sodium carbonate, sodium dodecyl sulfate and polyacrylamide into the mixer, and then add an appropriate amount of water to the mixer for mixing, and the rotating speed during mix...

Abstract

The invention discloses a door and window sealing water-blocking material, which comprises the following raw materials by weight: 35-50% of butyl rubber; 15-30% by mass of epoxy resin; 20-30% by massof polyethylene rubber; 5-13% by mass of calcium chloride; 3-5% by mass of sodium carbonate; 2-6% by mass of lauryl sodium sulfate; 3-5% by mass of polyacrylamide; 2-7% by mass of an antistatic agent;3-5% by mass of an antioxidant; and 4-7% by mass of a softener. The prepared water-blocking material has good crack resistance and oxidation resistance, the phenomenon that the water-blocking material is aged or cracked in a high-temperature or low-temperature environment is prevented, the damage probability of the water-blocking material in the using process is reduced, the service life of the water-blocking material is prolonged, and the cost is reduced. Moreover, the water-blocking material prepared by the invention can generate an expansion effect after absorbing water, so that the sealing performance between the water-blocking material and doors and windows is improved, and the water-proof effect of the water-blocking material in use is improved.

Description

technical field [0001] The invention relates to the technical field of water blocking materials, in particular to a water blocking material for door and window sealing. Background technique [0002] Door and window sealing strips are mainly used in plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decoration doors and windows. The plastic steel door and window seals on the market are generally extruded from PVC, modified PVC, EPDM, elastomer seals (including TPV, TPE, TPR, SEBS), silica gel and other materials; door and window seals are divided into uses. Glass sealing strips, door leaf and door cover sealing strips and wool strips are divided into three categories. Glass sealing strips are used for sealing between glass, fan and frame. Door leaf and door covering sealing strips are mainly used for sealing between door panels and door frames. Seal between frame and fan. In the production and installation of ...
