Abstract
The invention discloses a kind of glue, raw material consists of: polyvinyl alcohol 10.26 parts, 84.93 parts of water, formaldehyde 3.74～4.21 parts, 0.05 3 parts of carbamide, hydrochloric acid 0.74～10.53 parts, and in sodium hydroxide and consumption, number is mass fraction.The glue that the present invention provides, is mainly used in preparing paint render or adding in cement mortar or concrete, with reinforced cement mortar or the adhesive strength of concrete, plays the bonding transitional function between basic unit and coating.
Description
Technical field
The present invention relates to a kind of glue, belong to glue technical field.
Background technology
Glue is the intermediate connecting bi-material, how occurs with water preparation, belongs to fine chemistry industry class, of a great variety, mainly with
Sizing, physical aspect, method for curing and the sorting technique of adherend material.(-1203 common winks do to common are instant glue
Glue-cyanacrylate strength instant adhesive is a kind of), epoxy bond class, anaerobism glue, UV glue (ultraviolet
Photocuring class), PUR, pressure sensitive adhesive, latex class etc..
Summary of the invention
Purpose: for solving the deficiencies in the prior art, the present invention provides a kind of glue.
Technical scheme: for solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of glue, its raw material consists of: polyvinyl alcohol 10.26 parts, 84.93 parts of water, formaldehyde 3.74～4.21 parts, carbamide
0.05-3 part, hydrochloric acid 0.74～10.53 parts, in sodium hydroxide and consumption, number is mass fraction.
Preferably, described glue, it is characterised in that its raw material consists of: polyvinyl alcohol 10.26 parts, water
84.93 parts, 4.00 parts of formaldehyde, 1.55 parts of carbamide, hydrochloric acid 5.00 parts, in sodium hydroxide and consumption, number is mass fraction.
The preparation method of described glue, comprises the following steps:
1) add water in reaction pot, be warming up to 70 DEG C, the most slowly add polyvinyl alcohol, and be warming up to 90～95 DEG C, make to gather
Vinyl alcohol is completely dissolved；
2) poly-vinyl alcohol solution is cooled to 80～85 DEG C, drips hydrochloric acid, be stirred for 20 minutes, add formaldehyde and be condensed, greatly
About need about 60 minutes；
3) after lowering the temperature and regulate pH value, add carbamide and carry out amination process, sampled after the assay was approved pH is adjusted to neutrality,
Lower the temperature 40～50 DEG C, discharging and get final product.
Preferably, the preparation method of described glue, it is characterised in that: the pH value of described glue is 7～8.
Preferably, the preparation method of described glue, it is characterised in that: the proportion of described glue is 1.05.
Beneficial effect: the glue that the present invention provides, with the paint render of this glue configuration, except in use not containing
Free formaldehyde will not be poisoned outside workmen, after engineering terminates, owing to " protection " of outside one coating acts on, in putty
Connecing property of station is strong, mixes Guangxi 500 mesh dry powder, joins the dry powder of 2 kilograms by 1KG glue, thin scrape one layer after, after parching 80%,
Scrape the sand papering of one layer of use 200 mesh again.The not only mildew-resistant of such metope, hardness is good, reduces the consumption of emulsion paint simultaneously, makes room
The dicoration of inner wall surface is more preferably.
