Abstract

The invention discloses a solid thermoplastic glass resin comprising the following components in percentage by weight: 52-56 percent of methymethacrylate, 34-38 percent of butyl methacrylate, 9-11 percent of chlorinated polypropylene resin and 0.9-1.1 percent of silane coupling agent. The invention also discloses a preparation method of the resin, comprising the following steps of: heating an amount of deionized water to 78-82 DEG C and then putting 52-56 percent of methymethacrylate, 34-38 percent of butyl methacrylate and 0.9-1.1 percent of silane coupling agent into the deionized water for reaction polymerization; heating to 88-92 DEG C and then adding 9-11 percent of chlorinated polypropylene resin and pressurizing to 0.48-0.52kg for polymerization; ending the polymerization reaction at the temperature of 103-107 DEG C, carrying out cooling after the heat preservation is carried out for 45 min, and then blowing, dewatering and drying. The invention realizes convenient transportation, long shelf life and good adhesive force by aiming at the defects of inconvenient transportation, short shelf life and the like of the traditional liquid glass resin.

Description

Solid thermoplastic glass resin and preparation method thereof

Technical field

The present invention relates to a kind of organic cpds and preparation method thereof, be specifically related to a kind of solid thermoplastic glass resin and preparation method thereof, this resin is important source material such as glass surface coating, printing ink, belongs to environmental protective type chemical material technology field.

Background technology

At present, domestic do not have solid glass resin dedicated, and the liquid glass resin of import is owing to be solvent type, and not environmental protection, belongs to dangerization article, transportation, store all pretty troublesome, and quality guaranteed period weak point.

Summary of the invention

Goal of the invention: the objective of the invention is provides a kind of solid thermoplastic glass resin in order to solve the deficiency of prior art.

Another object of the present invention is for a kind of preparation method of solid thermoplastic glass resin is provided.

The technical scheme that the present invention adopts: a kind of solid thermoplastic glass resin; It comprises following component by mass percent: methymethacrylate 52%-56%; Methylacrylic acid fourth fat 34%-38%, chlorinated polypropylene 9%-11%, silane coupling agent 0.9%-1.1%.

A kind of preparation method of solid thermoplastic glass resin may further comprise the steps:

1, appropriate amount of deionized water is warmed to 78-82 ℃ of methymethacrylate that drops into said ratio, reactive polymeric in methylacrylic acid fourth fat and the silane coupling agent;

2, being warmed up to 88 ℃-92 ℃ chlorinated polypropylenes that add said ratio is pressurized to 0.48-052kg and carries out polymerization;

3, polyreaction finishes in the time of 103-107 ℃, is incubated cooling in 45 minutes, the blowing dewatered drying.

As optimization, the mass percent of said methymethacrylate is 54% of a said glass resin.

As optimization, the mass percent of said methylacrylic acid fourth fat is 35% of a said glass resin.

As optimization, the mass percent of said chlorinated polypropylene is 10% of a said glass resin.

As optimization, the mass percent of said silane coupling agent is 1% of a said glass resin.

The present invention adopts the acrylics raw material of methymethacrylate and methylacrylic acid fourth fat, and to be major ingredient, appropriate amount of auxiliary materials and auxiliary agent synthetic through the suspension polymerization process copolymerization, and the present invention's pearl particle that is white in color is dissolved in lipid, ketone, aromatic hydrocarbons and chlorinated solvent; Amount of solid >=99.9, molecular weight are 50000, softening degree is 9 at 145 degree, acid number, pack with laminated bag, transport very convenient; And the storage time is long; All underwent no deterioration in 3 years 5 years, considerably beyond the shelf lives of solvent type resin, and better to the sticking power of glass; Being suitable for as raw materials such as glass surface coating, printing ink, is the tailored version resin.

Beneficial effect: deficiencies such as the present invention is directed to transportation that existing liquid glass resin exists, store trouble, the quality guaranteed period is short, realize making things convenient for transportation, long quality-guarantee period, sticking power good.
