Embodiment 1

[0017] A polyester adhesive, which is composed of two components, A and B:

[0018] The first component is composed of the following raw materials in parts by weight: n-butanol 8, 307 unsaturated polyester 60, talcum powder 2, aluminum powder 4, calcium carbonate 20, triethylenetetramine 1, chlorobenzene 35;

[0019] Add the above-mentioned raw materials in parts by weight into a stirred tank, and stir under vacuum for 1 hour at a temperature of 120°C to obtain component A;

[0020] The B component is composed of the following raw materials in parts by weight: propylene glycol 80, toluene diisocyanate 15, dibutyltin dilaurate 0.2, phenyl salicylate 0.5, modified nano clay 1.2;

[0021] Add the raw materials in the above parts by weight into the stirring and dispersing kettle, and stir at high speed for 18 minutes to obtain component B;

[0022] The preparation method of the modified nano-clay is as follows: mix the clay with 3% dicumyl peroxide by mass, heat to 60°C and stir ...

Abstract

The invention discloses a polyester adhesive which is composed of components A and B, wherein the component A is composed of the following raw materials: n-butyl alcohol, 307 unsaturated polyester, talcum powder, aluminium powder, calcium carbonate, triethylene tetramine and chlorobenzene; the component B is composed of the following raw materials: propylene glycol, toluene diisocynate, dibutyltin dilaurate, phenyl salicylate and modified nanometer argil; and the polyester adhesive is formed by mixing and uniformly stirring the components A and B in the mass ratio of 1:5. According to the invention, by using the modified nanometer argil, the produced polyester adhesive has various good performances of traditional adhesives and has the advantages of low shrinkage rate, high adhesive strength, stable size, good electrical performance, chemical medium resistance, simpleness in preparation and process, little damage, no environmental pollution and the like; and the polyester adhesive disclosed by the invention has the beneficial effects of long storage time, benefit of the reduction of waste products, longer working life, higher curing speed, convenience for customer operation and capability of reducing the glue waste and finally increasing the overall quality of the product.

Description

[0001] Technical field [0002] The invention is the main type of adhesive, especially involving a polyester adhesive. Background technique [0003] Polyester resin is divided into saturated polyester and unsaturated polyester resin.The saturated common polyester resin is a product of benzene di major acid, 1,4-butanol, one-shrimpid glycol, hexyl acid, or citrinic acid cluster. It has a certain crystallinity, good rigidity, and elasticity.Different diversified acids and polyols can synthesize saturated polyester resins of different types and characteristics.If the two -way glycol and binary acid J of the direct chain structure are used, the polyester resin contains only the straight -chain structure.What produces is a polyester resin containing the benzene structure. If you use a chemical reaction to introduce other ingredients other than polyol and diversified acid, it produces modified polyester resin.If the synthetic polyester resin uses a polyol and diversified acid with a st...
