Abstract
The present invention relates to an aldehyde free adhesive for building, which is suitable for building engineering, indoor decorative and finish engineering and casting. The present invention is characterized in that the aldehyde free adhesive for building is composed of (2599)2 to 12% of polyvinyl alcohol, 0.001 to 0.68% of sodium sulfate, 0.002 to 0.08% of hydroxyethyl cellulose, (7010)0.001 to 0.8% of propanediol poly-oxypropylene polyvinylether, (40Be degree)0.5 to 6.6% of water glass, 0.001 to 1% of sodium tetraborate decahydrate, 0.5 to 4.5% of urea, 0.01 to 1% of sodium benzoate, and 73.34 to 96.985% of water. The present invention has the characteristics of no toxic material or air pollution, no harm to production operators and users, sufficient raw material which can be bought in China, and low cost, and the present invention is in accordance with the requirements of environmental protection and is a substitute of a polyvinyl formal adhesive (known as a Polyvinyl formal adhesive for construction 107). Thus, the present invention has strong practicability and wide range of application.
Description
(1) technical field:
The present invention belongs to the tackiness agent that a kind of single component of high polymer is formed, and is mainly used in construction work, indoor decorating engineering and casting and sticks with glue agent.
(2) background technology:
Chinese patent discloses a kind of polyvinyl formal adhesive for casting No. 87101061, adopts polyvinyl alcohol to make main raw material, adds formaldehyde and makes polyvinyl formal by aldolization, then the tackiness agent that is mixed and made into Walocel MT 20.000PV.
The tackiness agent of Chinese patent application number 02116588.2 application, the tackiness agent that adopts polyvinyl alcohol (1799), sodium sulfate Semen Ricini oil and ethylene oxide condensate (EL-40), propanediol polyoxypropylene polyvinyl ether (7010), Walocel MT 20.000PV, water glass (40Be °), borax, sodium hydroxide, rosin, water to be mixed and made into.
Construction work at present and interior decoration and casting stick with glue agent, use formaldehyde polyvinyl acetal mostly, be commonly called as 107 glue, be the acetal glue of making by aldolization by polyvinyl alcohol and formaldehyde, therefore the tackiness agent of making always has residual free formaldehyde, formaldehyde is a kind of poisonous and hazardous material, it can cause serious atmospheric pollution, bring great personal injury for production operator and user, though and the tackiness agent of application number 02116588.2 application does not contain formaldehyde but its mainly suitable glued board, the Bamboo and wood product of veneer sheet or the like bonding is not suitable for construction work, fitting-out work and casting are used.
(3) summary of the invention:
The objective of the invention is to improve above-mentioned problems of the prior art, the present invention develops a kind of Nonpoisonous, non-environmental-pollution, does not cause atmospheric pollution, compliance with environmental protection requirements to reach the novel non-formaldehyde architecture adhesion agent of GB (2001) 18583 every indexs.
1. this tackiness agent is characterized in that by the preparation of following components in weight percent:
Polyvinyl alcohol (2599) 2-12%
Sodium sulfate (analytical pure) 0.001-0.68%
Natvosol 0.002-0.08%
Propanediol polyoxypropylene polyvinyl ether (7010) 0.001-0.8%
Water glass (40Be °) 0.5-6.6%
Borax (analytical pure) 0.001-1%
Urea 0.5-4.5%
Sodium Benzoate 0.01-1%
Water 73.34-96.985%
This adhesive preparation method it is characterized in that in retort, adding by weight percentage 73.34-96.985% water 3/4 and be warming up to 80 ℃ of polyvinyl alcohol limits that add 2-12% and stir and just be warming up to 90 ℃ and all dissolve until polyvinyl alcohol, stop heating, the sodium sulfate that adds 0.001-0.68% after restir 10-15 minute, the Natvosol of 0.002-0.08%, the propanediol polyoxypropylene polyvinyl ether of 0.001-0.8% fully stirred 10-15 minute, the water glass limit edged that slowly adds 0.5-6.6% then stirs, added the back restir 10-15 minute, the borax that adds 0.001-1% more at twice, add for the first time and answer 3/4 of dosage, adding the back fully stirs, and then add remaining 1/4 fully stirring again, add the urea of 0.5-4.5% and Sodium Benzoate and 1/4 remainder water of 0.01-1% at last and fully stir again.
Because the present invention has selected polymerization degree height for use, viscosity is big, the polyvinyl alcohol that film forming power is strong (2599) is as main raw material, under the effect of inorganic salt sodium sulfate, macromolecular mass is dispersed, add again water glass (40Be °) afterreaction generate have-silicon-oxygen-silicon-group, the product side chain is increased, molecule increases, form reticulated structure, and then adding borax, can constitute the key of two glycol shapes again once more, make polyvinyl alcohol that chemical transformation further take place, thereby have better film forming power and bonding force, and can improve the water tolerance of filming, wherein propanediol polyoxypropylene polyvinyl ether (7010) is a defoamer, can eliminate the foam that produces in the chemical reaction, Natvosol is a thickening material, and urea is the not gelation of polyvinyl alcohol macromolecular mass that makes after chemical reaction for the stablizer purpose, keep good flowability, Sodium Benzoate is that sanitas prevents that glue is rotten.The present invention specifies unit to detect through Tianjin Bureau of Technical Supervision, every index all meets the requirement of 2001GB18583, its production technique is simple, in whole process of production, do not have the discharging of poison gas or venom, create good working environment to production operator, to operator itself also without any injury, simultaneously product itself be nontoxic environmentally friendly machine to the user too without any injury, the raw materials used source of the present invention simultaneously is sufficient, can purchase on the market at home, and is with low cost.This tackiness agent stripping strength (180 °) N/25mm is that 15.8 technical indicators greater than polyvinylformal glue are polyvinylformal glue (107 glue) the ideal substitute products that are widely used in construction work, interior decoration engineering and casting aspect at present.Therefore, it is practical, and range of application is wide.
