Problems solved by technology

[0006] However, the epoxy joint adhesive products in the prior art, as the storage time prolongs, are prone to sedimentation and delamination, yellowing and odor; as the use time increases, the adhesive force decreases significantly, and the application site is prone to yellowing, which affects Adhesive effect; In addition, during the application process of epoxy joint adhesive products in the prior art, the viscous resistance is often too large, which affects the construction efficiency, and it is easy to sag before it is completely cured, which affects the construction effect

Abstract

The invention provides epoxy seam gum and a preparation method thereof. The epoxy seam gum provided by the invention is prepared from raw materials with specific components and usage, has a strong bonding force for a gypsum board, marble, cement, wood and various metal materials and no yellowing and can be used for a long time. The epoxy seam gum adopts a complex rheological modification system and has the advantages of moderate viscous resistance in allocating, batch scratching and reforming processes, no sagging, excellent construction property and high construction efficiency; the epoxy seam gum can be used after a component A and a component B are uniformly mixed according to the proportions; during construction, the epoxy seam gum is convenient to allocate and simple in metering; the method disclosed by the invention is simple in process and suitable for large-scale production; comprehensive performance of the epoxy seam gum can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction adhesives, in particular to an epoxy joint adhesive and a preparation method thereof. Background technique [0002] Epoxy joint adhesive mainly has the following advantages: [0003] 1. It can be constructed on wet, dry and other base surfaces. It has long service life, weather resistance, aging resistance, oil resistance and certain acid resistance; waterproof and anti-corrosion performance; non-toxic, tasteless, non-polluting, safe and easy construction , short construction period and other advantages; [0004] 2. Waterproof, moisture-proof, leak-proof, mildew-proof, anti-corrosion, smooth and wear-resistant, and the consolidated body is non-toxic; [0005] 3. The coating is resistant to acid, alkali, salt and oil, and various solvents and chemicals; it has excellent flame retardancy and insulation. [0006] However, the epoxy joint adhesive products in the prior art, as the storage time...
