According to our test, it is found that after bonding and curing the SBS spray glue on the market, the glue layer is easy to pulverize. Even if it is not exposed to the sun indoors, most of the spray glue will powder within 10-15 days. If it is exposed to the sun for 2 to 6 hours, it will be severely pulverized. Some furniture will be pulverized in the sponge before it is fully finished, which will seriously affect the internal quality of the furniture.
In order to avoid this situation, some high-end furniture factories choose water-based neoprene spray glue and oil-based neoprene spray glue, which are not so convenient for process operation. Water-based neoprene spray glue has complicated equipment, poor bonding feel, high cost, and poor low temperature adaptability; Neoprene spray glue generally contains toxic solvents such as toluene and chlorinated hydrocarbons when it dissolves. The spraying smell is large, it is harmful to the human body, and the cost is high. The pulverization is particularly good, but it cannot compare with SBS spray glue in terms of cost, environmental protection, and actual bonding operability
Existing SBS glue-spraying technology actually uses SBS to modify the tackifying resin. The tackifying resin accounts for the main mass. chalking

Embodiment 1
[0063] (1) Preparation of alkylphenolic resin magnesium oxide chelate:
[0064] S1. cyclohexane (88 parts), non-aqueous catalyst NMP (2.1 parts) are dropped into the kettle and stirred;
[0065] S2. then add high reaction type alkyl phenolic resin (100 parts) into the reactor to dissolve;

Abstract
The invention discloses a chalking-resistant spray gel and a preparation method thereof. The chalking-resistant spray gel is prepared from the following raw materials in parts by weight: 10 to 16 parts of butadiene-stryrene copolymer elastomer, 10 to 18 parts of hydrogenated rosin, 3 to 16 parts of hydrogenerated pentaerythritol rosin resin, 1 to 5 parts of alkyl phenolic resin magnesium oxide chelating matter, 5 to 8 parts of styrene block graft polymer, a proper amount of dispersing solvent, and 1 to 2 parts of solvent, wherein the viscosity of the alkyl phenolic resin magnesium oxide chelating matter is greater than 3000cps when determining by a No.3 rotor at the temperature of 25 DEG C; the styrene block graft polymer is prepared from the following raw materials in parts by weight: 100 parts of styrene block copolymer, 2 to 6 parts of MAH (maleicanhydride) monomer, 10 to 20 parts of HEMA (hydroxyethyl methacrylate) monomer, 30 to 40 parts of MMA (methyl methacrylate) monomer, 0.3 to 0.4 part of initiator, and 350 to 400 parts of solvent; the styrene block graft polymer is prepared by firstly grafting the styrene block copolymer, the MAH monomer and the HEMA monomer and then grafting with the MMA monomer; the styrene block copolymer is selected from one or several of SBS (styreneic block copolymers) or SIS (styrene isoprene styrene). The chalking-resistant spray gel has good chalking-resistant property.
Description
technical field [0001] The invention relates to the field of adhesives, and more particularly, to a powder-resistant spray adhesive and a preparation method thereof. Background technique [0002] At present, most of the spray glues for furniture manufacturing on the market are spray glues made of styrene-butadiene-styrene block copolymer (SBS) and tackifying resins, and water-based chlorine is used in a few occasions. Butadiene spray glue and oil-based neoprene spray glue. According to our test, it is found that after the SBS spray glue on the market is cured, the glue layer is prone to chalking. If it is exposed to the sun for 2-6 hours, the powder will be very serious. When some furniture is not fully finished, it will be found that there is powder in the sponge, which will seriously affect the inherent quality of the furniture. In order to avoid this situation, some high-end furniture factories choose water-based neoprene spray glue and oil-based neoprene spray glue, wh...
