Abstract

The present invention discloses a multipurpose all-purpose decorative glue without benzene poison for the production and the manufacture of furniture handicrafts in architectural decoration industry, etc. The decorative glue is made from the components: 30 to 40 shares by weight of SBS 792, 20 to 30 shares by weight of rosin ester, 20 to 30 shares by weight of terpene resin, 70 to 80 shares by weight of gasoline 66#, 80 to 90 shares by weight of trichloroethylene and 0.2 to 0.8 share by weight of nucleating agents. The decorative glue has the advantage that the manufacture is simple, the variety of the required raw materials is simplified, and the cost is lower than that of similar products; the decorative glue has no benzene poison; the viscosity is lower than that of the similar products, and is only 100 to 250mpa; the glue solution is not frozen at the temperature of 0 DEG C to-35 DEG C in winter, and thus, the decorative glue is conveniently used under different environments; the viscous holding time is long, the decorative glue can be freely glued after being applied through 15 to 60 minutes, and the adhesion effect is not affected; the sold constituent is high, the solvent dosage is reduced, and the pollution on atmosphere is reduced; the heat resistance performance is good.

Description

Multipurpose universal decoration adhesive

Technical field

The present invention is a kind of without benzene toxicity multi-purpose adhesive that is applied to architectural decoration, and can be applied to the spray glue of furniture manufacturing usefulness and the multipurpose universal decoration adhesives such as spray glue that artwork is manufactured usefulness.

Background technology

The disclosed without benzene toxicity universal decoration adhesive of prior art generally adopts SBS, application number is 99112745, the applying date is that March 16, denomination of invention in 1999 are ethene-divinyl-styrene type flame-retarding fire-extinguishing universal adhesive without benzene toxin, it is that 12 kinds of chemical substances such as SBS (that is: vinylbenzene-divinyl-polystyrene ternary segmented copolymer), terpine resin, linking agent, fire retardant are mixed by a certain percentage, produces qualified product after stirring.Though it has following advantage: 1. cut off without benzene toxicity; 2. flame retardant effect is obvious; 3. do not freeze at-23～-30 ℃ of glues winter; 4. smell is less, and bonding force is strong; 5. cost is lower than former chlorobutyl benzene-free fire-retarded universal glue.But component is many, manufacturing step is many and complicated, and tack retention hour falls short of.

Goal of the invention

The object of the present invention is to provide that a kind of purposes is wide, component and make universal decoration adhesive more simple, that tack retention hour is grown, cost is lower, smell is littler.

Summary of the invention

In order to achieve the above object, the present invention adopts following scheme to realize: it is that 6 kinds of chemical substances such as SBS792 (or SBS1401, TR2000), rosin fat, terpine resin, trieline, 6# gasoline are mixed by a certain percentage, produces qualified product after stirring.Its component is (part is a weight unit): SBS792 30～40, rosin fat 20～30, terpine resin 20～30,6# gasoline 70～80, trieline 80～90, nucleus agent 0.2～0.8.

Beneficial effect

Compared with the prior art this product has following advantage: 1, make simply, the desired raw material kind is simplified, and cost is lower than like product; 2, exhausted without benzene toxicity; 3, viscosity is low than like product, has only 100～250mpa.s, and winter, 0 ℃～-35 ℃ glues did not freeze, convenient under varying environment, use, and during construction, brushing and spraying all can, construction area is big, the operating efficiency height reduces construction cost; 4, tack retention hour is long, can be behind gluing in 15～60 minutes random time bonding all can, do not influence adhesive effect; 5, the solid content height reduces solvent load, reduces atmospheric pollution; 6, resistance toheat is good.

Specific embodiment:

At first 35 parts of load weighted SBS792 (part is a weight unit), 25 parts in rosin fat, 25 parts of terpine resins, 75 parts in 6# gasoline, 85 parts of trielines, nucleus agent are put into reactor for 0.4 part, stirred 6-12 hour, setting-out is afterwards observed, when whole material dissolutions are thorough, blowing packing warehouse-in.

Through the product sampling inspection, its performance index such as following table:

Sequence number	Project	Unit	Standard-required	Assay
					1	Outward appearance		The even thick liquid of yellow or brown, no suspended substance does not have visible mechanical impurity, no phenomenon of phase separation	Meet
2	Non-volatile content	％	≥20	35.8
					3	Viscosity (25 ℃)	Pa.s	2～8	2.5
4	Tensile shear strength	MPa	≥1.56	1.65
					5	Initial cohesiveness	MPa	≥0.7	0.87
6	The dry heat resistance performance		120 ℃, no bubbling does not have the phenomenon of coming unglued	Meet
