Abstract
The invention relates to a colourless and transparent fast-curing adhesive and a manufacturing method thereof, and belongs to the field of daily-use chemical preparation. The colourless and transparent fast-curing adhesive is prepared from the following materials in parts by weight: 20-40 parts of thiohydracrylic acid, 10-25 parts of pentaerythritol, 20-35 parts of organic solvent G-10, 10-30 parts of water absorbent A-10, and 10-30 parts of E-51 epoxy resin. The preparation method comprises the following steps: mixing thiohydracrylic acid, pentaerythritol and an organic solvent G-10, reacting at 80-120 DEG C in the presence of nitrogen, adding the water absorbent A-10, further reacting for 1-3h, then collecting a crude product, namely pentaerythritol tetrakis(3-mercapto-propionate), and carrying out chain extension on pentaerythritol tetrakis(3-mercapto-propionate) and E-51 epoxy resin, thereby obtaining the colourless and transparent fast-curing adhesive. The adhesive has a viscosity of 880mPa.s, and is colourless and transparent, suitable for adhesion of high-grade leather products, and beneficial to improvement on the appearance beauty of the leather products.
Description
Technical field
The present invention relates to a kind of sizing agent and manufacture method thereof, specifically a kind of water white transparency fast setting sizing agent and manufacture method thereof, belong to daily use chemicals production technical field.
Background technology
Epoxy resin (Epoxy Resin) refers to the epoxy group(ing) containing two or more, forms the thermosetting polymer polymkeric substance with body mesh network structure with organic compound such as aliphatics, alicyclic or aromatic series for skeleton and by the reaction of epoxy group(ing).Epoxy resin after solidification has good physics, chemical property, it has excellent bonding strength to the surface of metal and non-metallic material, dielectric properties are good, set shrinking percentage is little, product size good stability, and hardness is high, soft better towards property, to alkali and most of solvent-stable, be thus widely used in national defence, each department of national economy, do around purposes such as note, Jin Cheongju, lamination material, caking agent, coating.
Mechanical property is high, cure shrinkage is little, adhesive property is excellent, process operability is good, photo and thermal stability is good, dielectric properties are good and high heat resistance etc. is all the outstanding advantages of the condensate performance of epoxy resin.Epoxy resin coordinates solidifying agent, promotor, properties-correcting agent, increasing towards agent and other additive, can form numerous combinations and formula, make wherein certain performance especially outstanding, with some special applications requirement competent.In all thermosetting resins, the over-all properties of epoxy resin is best, but compares with other resin high on cost, but along with going deep into of scientific research and exploitation, cost is also in slip, and especially requiring high field to over-all properties, market application foreground is very optimistic.
Ring Gas resin adhesive is widely used, and has excellent viscosifying power to multiple material, has the advantages such as cohesive strength is high, electrical property is excellent, shrinking percentage is low, dimensional stabilizing, weathering resistance are strong.Many sulfydryls solidifying agent collocation Tertiary amine accelerators and epoxy resin, with the use of showing water white transparency and the fast advantage of curing speed, become the class solidifying agent being subject to extensive concern in recent years.
Epoxyn is a kind of reactive adhesive, is converted into the molecules immobilized thing of build and reaches certain mechanical property, thermostability, resistance to acids and bases by the curing reaction of A, B component by linear molecule.The final performance of two kinds of components to cured product all plays conclusive effect.And A, B component formula consumption increase or reduce also can have an impact to cured product character.The preparation carrying out tackiness agent according to different service requirementss is a very important job.For common epoxy glue, the transparency of set time, cured product all can not meet the quick-setting requirement of water white transparency, therefore require quick-setting, cured product is colourless, the development of the solidifying agent of higher-strength and weathering resistance also needs gordian technique.
Chinese invention: 201210449970.0; Disclose a kind of sizing agent, comprise epoxy resin 100 parts, ethanol 5-18 part, glycerol 2-7 part, vinylformic acid 40-60 part, turps 7-9 part.This sizing agent prepared composition is simple, with low cost, but this sizing agent does not solve the heavy problem of smell, is not suitable in the preparation technology of senior leatherware.
Summary of the invention
The object of this invention is to provide a kind of sizing agent, this sizing agent viscosity is 880mPa.s(65 DEG C), water white transparency, is suitable in the bonding of high-grade leatherware, is conducive to the outward appearance Mai Tai improving leatherware.
A kind of water white transparency fast setting sizing agent, is obtained by following weight part:
Thiohydracrylic acid 20-40 part, tetramethylolmethane 10-25 part, organic solvent G-10 20-35 part, water-retaining agent A-10 10-30 part, E-51 epoxy resin 10-30 part.
A kind of preparation method of water white transparency fast setting sizing agent is:
Thiohydracrylic acid, tetramethylolmethane, organic solvent G-10 are mixed, nitrogen protection 80-120 DEG C of reaction, adds after water-retaining agent A-10 continues reaction 1-3h and collect crude product, be four thiohydracrylic acid pentaerythritol esters, itself and E-51 epoxy resin are carried out chain extension.
The present invention relative to the beneficial effect of prior art is:
Compared with other sizing agents, sizing agent viscosity of the present invention is 880mPa.s(65 DEG C), paste intensity high, set time is short, and visible light transmissivity is high, water white transparency, is suitable in the bonding of high-grade leatherware, is conducive to the outward appearance Mai Tai improving leatherware.
