Example Embodiment

[0012] Example 1

[0013] A butyl sealant, the raw materials in parts by weight include: 55 parts of butyl rubber, 29 parts of natural rubber, 40 parts of petroleum resin, 6 parts of titanium dioxide, 4 parts of antioxidant D, 160 parts of xylene, and 20 parts of fumed silica Parts, 99 parts of talc, 9 parts of thickener, 17 parts of humectant, wherein the humectant is glycerol, the thickener is dioctyl phthalate; the butyl rubber, natural rubber, antioxidant D, After the titanium dioxide was mixed in an open rubber mixer for 30 minutes, the roller pitch of the rubber mixer was adjusted to 1.7 cm to obtain a film sheet. The film sheet was soaked in a xylene solvent for 27 hours to obtain a glue solution. Knead in the kneader until the glue is uniform and free of particles, and then add petroleum resin, humectant, thickener, talc, and fumed silica for 13 minutes to obtain a butyl sealant.

Example Embodiment

[0014] Example 2

[0015] A butyl sealant, the raw materials by weight include: 60 parts of butyl rubber, 25 parts of natural rubber, 46 parts of petroleum resin, 8 parts of titanium dioxide, 7 parts of antioxidant D, 155 parts of xylene, and 15 parts of fumed silica Parts, 105 parts of talc, 10 parts of thickener, 20 parts of humectant, wherein the humectant is propylene glycol, and the thickener is dibutyl ester; butyl rubber, natural rubber, antioxidant D, and titanium dioxide are mixed in an open mill After mixing in the rubber machine for 25 minutes, adjust the roller pitch of the rubber mixing machine to 1 cm to obtain a film sheet, soak the film sheet in xylene solvent for 30 hours to obtain a glue liquid, and throw the glue liquid into the kneader to knead the glue. The liquid is uniform without particles, and then petroleum resin, humectant, thickener, talcum powder, fumed white carbon black are added and kneaded for 15 minutes to obtain butyl sealant.

Abstract

The invention discloses a butyl sealant comprising the following raw materials by weight: 55-65 parts of butyl rubber, 20-30 parts of natural rubber, 40-50 parts of petroleum resin, 3-8 parts of titanium dioxide, 4-9 parts of antioxidant D, 140-160 parts of xylene, 15-25 parts of fumed silica, 95-105 parts of talcum powder, 9-15 parts of a thickening agent and 10-20 parts of a moisturizing agent; the butyl rubber, the natural rubber, the antioxidant D and the titanium dioxide are mixed for 25-35min in an open mill for plastics to obtain a glue film sheet, the glue film sheet is placed in xylene solvent for soaking for 20-30h to obtain a glue liquid, the glue liquid is poured into a kneading machine for kneading until the glue liquid is even and free of particles, then the petroleum resin, the moisturizing agent, the thickening agent, the talcum powder and the fumed silica are added for continuing kneading for 8-15min to obtain the butyl sealant. The butyl sealant has excellent air tightness and is used for doors and windows and other places with high air tightness requirements.

Description

Technical field [0001] The invention relates to the technical field of sealants, in particular to a butyl sealant. Background technique [0002] Sealant is a kind of sealing material that deforms with the shape of the sealing surface, does not flow easily, and has a certain adhesiveness. It is an adhesive used to fill the gap in the configuration to play a sealing role. Usually dry or non-dry viscous materials such as natural resin, synthetic resin, natural rubber, synthetic rubber and asphalt are used as base materials, combined with inert fillers such as talc, titanium dioxide, clay, carbon black and asbestos, and then added It is made of solvent, plasticizer, curing agent, accelerator and other additives. The sealants in the prior art are mostly used in the construction industry, especially for sealing at doors and windows. They have the functions of bonding, sealing, waterproofing, and heat insulation, but are often affected by environmental factors. The sealants in the prio...
