The invention relates to general terylene staple fiber oil, which mainly solves the problems of great pungent taste, instability of oil emulsion and the like of existing oil. The general terylene staple fiber oil comprises the following components: (1) an anionic surfactant and (2) a nonionic surfactant which uses polyoxyethylene chain segments as hydrophilic groups; the anionic surfactant comprises at least one of phosphate ester A and phosphate ester B; the phosphate ester A comprises at least one of a compound as shown in a formula I and a compound as shown in a formula II; the phosphate ester B comprises at least one of a compound as shown in a formula III and a compound as shown in a formula IV, wherein R1 to R9 are hydrocarbyl; M1 to M9 are selected from H, alkali metals or ammonium; n is equal to 1 to 5, so that the technical problem is solved, and the technical scheme can be used for industrial production of the general terylene staple fiber oil.

The invention discloses a gluing device for a pipe fitting, which comprises a supporting seat, wherein the supporting seat is provided with a first through hole; a clamp used for the pipe fitting to pass through and clamping the pipe fitting, wherein one end of the clamp is fixedly connected with the supporting seat, and a position of the clamp where the pipe fitting passes through corresponds tothe first through hole; a first driving mechanism connected with the clamp, wherein the first driving mechanism drives the clamp to contract radially so as to form a clamping action on the pipe fitting; a glue feeding mechanism for conveying the glue to the surface of a work piece; a mounting seat provided with a through hole, wherein a rotating shaft is arranged in the through hole, and two endsof the rotating shaft are respectively exposed outside the through hole; a gluing mechanism, wherein one end of the gluing mechanism is fixedly connected with one end of the rotating shaft; a drivingmechanism connected with the other end of the rotating shaft, wherein the driving mechanism drives the rotating shaft to rotate so as to brush the glue on the surface of the pipe fitting. The device facilitates reducing production cost.

The invention provides a net-flavor full-matt ultraviolet-curing coating, which is prepared from the following components by weight percentage: 20-35 percent of ultraviolet curing resin, 40-57 percent of reactive acrylate monomers, 8.0-14 percent of organic matt powder, 0.8-4.0 percent of wax powder, 3.0-10 percent of photoinitiator, 0.2-0.5 percent of defoamer, 0.2-1.0 percent of flatting agent and 0.5-2.0 percent of wetting dispersant. The method is as follows: ultraviolet curing modified polyester acrylic resin with 90-98 percent of solid content is adopted to obtain the moderate hardness of paint film; and three kinds of reactive monomers are combined, the total content percentage of the monomers in the coating is reduced, the adhesive force, the hardness, the hand feeling, the glossiness and the fullness of paint film are increased, and the problems of odor, luster and the like before and after construction are solved. The selected resin is resin with a low functional group, and the reactive monomers are N-contained monomers. The coating has the adhesive force to various base materials, has low odor and is full-matt.

The present invention discloses a method for preserving natural latex and a latex product prepared thereby. A natural latex is preserved by adding bamboo charcoal. A small quantity of an ammonia stabilizer, or no ammonia stabilizer, is added to the natural latex, thus achieving preservation without ammonia or with a reduced amount of ammonia and giving the preserved natural latex little or no pungency without affecting storage life. The latex product is antimicrobial, has limited pungency, and has a long storage life. Moreover, the latex product has a far-infrared function and can promote microcirculation in the human body. Further, the latex product has excellent mechanical performance, adsorption, moisture-absorption and sweat-removing functions, and the like. The excellent performances contribute to the wide application of the natural latex.

The invention relates to an odorless ultraviolet-curing wood lacquer and a preparation method thereof. The wood lacquer is prepared from the following components in percentage by weight: 45-65% of ultraviolet-curing resin, 10-25% of reactive monomer, 5.0-15% of talcum powder, 5.0-15% of transparent powder, 0.5-1.0% of gas-phase silicon dioxide, 1.0-5.0% of photoinitiator, 0.2-0.5% of defoaming agent, 0.2-1.0% of leveling agent and 0.2-1.2% of wetting agent. The odorless ultraviolet-curing wood lacquer does not have irritating odor before and after construction, does not contain benzene, and can be used immediately after construction; and meanwhile, the surface effect and fullness are not inferior to those of nitrocellulose dope, unsaturated paint or polyester paint.

The invention provides odor-free wear-resistant ultraviolet curing coating and a preparation method thereof. The coating consists of the following components: ultraviolet curing resin, a reaction type acrylate monomer, a photoinitiator, an antifoaming agent, a leveling agent and a wetting dispersant. The coating provided by the invention is odor-free wear-resistant UV (Ultraviolet) curing coating which is used for coating processes including spray-coating, roller-coating, shower-coating and the like of suite furniture, cupboards, door plates and the like. Meanwhile, the wear resistance and the leveling effect are excellent, the top side is flat, GB18582-2009 and GB / T9756-2009 can be satisfied while the construction period is short, and poisonous and harmful substances including benzene, formaldehyde, free TDI (Toluene Diisocynate) and the like are not contained; moreover, the heavy metal content is far lower than the European standard, and therefore, the coating is a functional product with excellent environment-friendly performances, and benzene content (mg / M<2>) not bigger than 0.003 before and after the construction, and is also odor-free wear-resistant ultraviolet curing coating.
