preparation example Construction

[0013] The present invention also provides a preparation method of cyclodextrin binder, comprising cyclodextrin, glycerin, polymethyl methacrylate, sodium dodecylbenzenesulfonate, ethylene glycol dimethacrylate Mixed with rosin to make cyclodextrin binder.

[0014] In the above preparation method, the amount of each material can be selected within a wide range, but in order to make the prepared cyclodextrin binder have more excellent viscous properties and heat resistance, preferably, relative to 100 weight part of cyclodextrin, the consumption of glycerol is 30-35 parts by weight, the consumption of polymethyl methacrylate is 15-20 parts by weight, and the consumption of sodium dodecylbenzenesulfonate is 4-8 parts by weight, The consumption of ethylene glycol dimethacrylate is 17-35 parts by weight, and the consumption of rosin is 5-15 parts by weight.

[0015] In the above preparation method, the molecular weight of polymethyl methacrylate can be selected in a wide range, b...

Embodiment 1

[0019] At 25°C, cyclodextrin, glycerol, polymethylmethacrylate (weight average molecular weight: 20,000), sodium dodecylbenzenesulfonate, ethylene glycol dimethacrylate and rosin were mixed according to 100 :33:17:6:25:10 and mixed for 2.5 hours to prepare the cyclodextrin binder A1.

Embodiment 2

[0021] At 15°C, cyclodextrin, glycerol, polymethyl methacrylate (weight average molecular weight: 10,000), sodium dodecylbenzenesulfonate, ethylene glycol dimethacrylate and rosin were mixed according to 100 :30:15:4:17:5 and mixed for 2 hours to prepare the cyclodextrin binder A2.

Abstract

The invention discloses cyclodextrin binder and a preparation method thereof. The cyclodextrin binder includes cyclodextrin, glycerin, polymethyl methacrylate, sodium dodecyl benzene sulfonate, glycol dimethacrylate and rosin. The cyclodextrin binder has excellent binding performance, and meanwhile has excellent heat resisting performance.

Description

technical field [0001] The invention relates to a binder, in particular to a cyclodextrin binder and a preparation method thereof. Background technique [0002] The binder is the guarantee of the bonding strength between the abrasive and the matrix. With the development of the chemical industry, various new binders have entered the field of coated abrasives, which has improved the performance of coated abrasives and promoted the development of the coated abrasives industry. In addition to the glue, the adhesive also includes auxiliary components such as solvents, curing agents, toughening agents, preservatives, colorants, and defoamers. Binders include synthetic resins, rubber, and paint, in addition to the most commonly used animal glue. [0003] Although the existing adhesives have greatly improved the adhesive properties, it is often difficult to meet the production requirements in terms of heat resistance. Contents of the invention [0004] The object of the present...
