Abstract

The invention relates to the technical field of chemical adhesives and in particular relates to a production method of a non-toxic adhesive. The production method of the non-toxic adhesive comprises the following steps of: firstly, heating 2-5 parts by weight of polyvinyl alcohol and 45-90 parts by weight of deionized water to the temperature of 85-90 DEG C, insulating for 1-2 hours until polyvinyl alcohol and deionized water are completely dissolved, and filtering; secondly, respectively preparing 0.15-1.5 parts of sodium bicarbonate and 0.08-0.12 part by weight of potassium peroxodisulphate into aqueous solutions with the concentration of 10%; and thirdly, adding the polyvinyl alcohol solution, 0.2-0.5 part of n-octyl alcohol and 0.3-1 part of emulsifier into a reaction kettle, mixing to be uniform, and heating to temperature of 60-65 DEG C. According to the production method of the non-toxic adhesive, the polyvinyl alcohol solution is adopted as an adhesive, and the polyvinyl alcohol solution takes water as dispersion medium, contains no toxic solution or formaldehyde and can avoid a fire disaster and toxication, so that human health and environmental protection can be facilitated; besides, the adhesive prepared by the invention has the characteristics of water resistance, heat resistance and the like; and usage amount of the emulsifier is reduced, raw material is saved, and cost is reduced.

Background technology

Need to use in a large number tackiness agent in existing woodwork manufacturing processed, but existing tackiness agent contains the material that human body is had grand evil, as formaldehyde, benzene, toluene and multiple harmful volatile organic matter, these objectionable impuritiess have carinogenicity to human body, have a strong impact on the healthy of people.

Summary of the invention

The purpose of this invention is to provide a kind of water-fast, heat-resisting, do not contain poisonous solvent, be conducive to the production method of the avirulent adhesion agent of HUMAN HEALTH and environment protection.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the production method of avirulent adhesion agent comprises the following steps:

(1), by weight 45～90 parts of 2～5 parts of polyvinyl alcohol and deionized waters are heated to 85～90 ℃, be incubated 1～2 hour to all dissolvings, filter;

(2), by weight 0.08～0.12 part of 0.15～1.5 part of sodium bicarbonate and Potassium Persulphate is made into respectively 10% the aqueous solution;

(3), add 0.3～1 part of polyvinyl alcohol solution, 0.2～0.5 part of n-Octanol and emulsifying agent in reactor, after stirring, be warming up to 60～65 ℃;

(4), when equitemperature is warming up to 80～82 ℃, drip mix monomer and persulfate aqueous solution, described mix monomer adds with 10% speed per hour, persulfate aqueous solution adds with 5% speed per hour, be incubated 6～8 hours, be warming up to 90～95 ℃, be incubated 30 minutes;

(5), when being cooled to 50 ℃, add sodium bicarbonate aqueous solution, stirred 1.5 hours, discharging gets final product.

The present invention has following beneficial effect: the production method of avirulent adhesion agent of the present invention, adopt polyvinyl alcohol water solution as tackiness agent, because polyvinyl alcohol water solution is take water as dispersion medium, do not contain poisonous solution, formaldehydeless, fire and poisoning be can avoid, HUMAN HEALTH and environment protection are conducive to; In addition, the tackiness agent that the present invention makes has the characteristics such as water-fast, heat-resisting, wherein, has reduced the consumption of emulsifying agent, has saved raw material, has reduced cost, is widely used in the bonding of the woodwork plates such as glued board, shaving board.
