Technical Field
The invention belongs to the technical field of automobiles, and particularly relates to an automobile AB column framework cladding piece cladding process.
Background
At present, the sensory quality of the automotive interior parts is more and more concerned by customers, and the decorative parts in the automotive industry begin to be changed from original hard plastic parts into coated interior parts. The traditional method for coating the framework of the decorative plate on the automobile AB column is to treat the framework of the AB column by a flame gun, then add a hardening agent into the used glue in proportion, spray the glue once after heating the framework, wherein the glue has high solidification speed and needs to be heated at 80 ℃; the surface needs to be heated at 80 ℃ after being sprayed with glue for the first time; because the adhesion degree of the primary glue spraying glue is poor, secondary glue spraying is needed to be carried out on the framework and the surface; the process can not ensure the smoothness of the product skin, the adhesion degree of glue is poor, and the adhesion of bones and the skin can not be ensured; it needs specific temperature condition, but the surface plays the product in winkle and can not use, and skeleton surface glue can not clear up, causes very big expense, and manufacturing cost increases.
Disclosure of Invention
The invention aims to provide a coating process of an AB column framework coating piece of an automobile, which can enable the surface of the coating piece to be smooth and has no debonding and wrinkling phenomena.
In order to achieve the purpose, the invention provides the following technical scheme: the coating process of the automobile AB column framework coating piece is characterized by comprising the following steps of:
s1, uniformly covering and spraying benzene-free grafting adhesive on the framework;
s2, heating the framework;
and S3, coating the cladding piece on the framework.
Further, the temperature for heating the skeleton in S2 is 50-70 deg.
Further, the temperature at which the skeleton is heated in S2 is 60 degrees.
Further, the benzene-free grafting adhesive comprises the following components in parts by weight: 60-80 parts of chloroprene rubber, 20-30 parts of methyl methacrylate, 2-5 parts of an initiator, 1-3 parts of an antioxidant, 6-8 parts of a terminator, 10-15 parts of tackifying resin and 20-40 parts of an initiator cosolvent.
Further, the initiator is benzoyl peroxide, and the initiator cosolvent is acetone.
Further, the antioxidant is thiopropionate.
Further, the terminating agent is wood tar.
Compared with the prior art, the invention has the beneficial effects that: the AB column coating part manufactured by the process has a smooth surface, does not have the phenomenon of debonding and wrinkling, improves the product quality, and saves the manual cost.
Detailed Description
The technical solutions in the embodiments of the present invention will be described below clearly and completely in connection with the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a technical scheme for coating an AB column framework coating piece of an automobile, which comprises the following steps: a coating process of an AB column framework coating piece of an automobile comprises the following steps:
s1, uniformly covering and spraying benzene-free grafting adhesive on the framework;
s2, heating the framework;
and S3, coating the cladding piece on the framework.
The heating temperature for the skeleton in S2 is 50-70 deg.C, and the most preferable heating temperature for the skeleton in S2 is 60 deg.C.
After the benzene-free strong grafting medicinal liquid is used for pasting the yellow glue, the product does not need to carry out flame gun treatment on the framework, and the requirement of the viscosity of the framework and the surface skin can be met by uniformly covering and spraying the framework with the glue once. The AB column skeleton covering piece manufactured by the process has a smooth surface, does not have the phenomena of gel separation and wrinkling, improves the product quality, and saves the labor cost.
The benzene-free grafted rubber consists of chloroprene rubber, methyl methacrylate, an initiator, an antioxidant, a terminating agent, tackifying resin and an initiator cosolvent.
The tackifying resin is gum rosin which is a natural material. The gum rosin is a non-volatile natural resin which is obtained by taking pine resin as a raw material through different processing modes, is a hard and crisp transparent solid substance, is light yellow to yellow red, has the special fragrance in pine and has a thermoplastic vitreous substance. Gum rosin is a mixture of several components, which differ slightly from pine species, and is composed mainly of resin acids with small amounts of fatty acids and neutral substances. In general gum rosin, the content of resin acid is 85.6-88.7%, the content of fatty acid is 2.5-5.4%, and the content of neutral substance is 5.2-7.6%. The softening point is 70-90 ℃, the specific gravity is 1.070-1.085, the heat of dissolution is 15.8kcal/kg, and the gum rosin has crystallization characteristics and is easy to generate crystallization. Therefore, the glue has certain fragrance and no peculiar smell.
The antioxidant is thiopropionate, the terminating agent is wood tar, and the wood tar is a product (such as Swedish tar or pine tar) discharged when wood (needle-leaved wood or other wood) is carbonized in a charcoal kiln or a product (distillation tar) obtained by distillation in a distillation retort or a distillation furnace. The distillation tar can be obtained directly by precipitation from the tar water (precipitation tar) or by distillation of the tar water (tar already partially dissolved) (dissolution tar). The initiator is benzoyl peroxide, and the initiator cosolvent is acetone.
The benzene-free grafting adhesive comprises the following components in parts by weight: 60-80 parts of chloroprene rubber, 20-30 parts of methyl methacrylate, 2-5 parts of an initiator, 1-3 parts of an antioxidant, 6-8 parts of a terminator, 10-15 parts of tackifying resin and 20-40 parts of an initiator cosolvent.
Example one
The preparation raw materials of the benzene-free grafted rubber of the embodiment are composed of the following components in parts by weight: 70 parts of chloroprene rubber, 20 parts of methyl methacrylate, 3 parts of an initiator, 2 parts of an antioxidant, 6 parts of a terminator, 13 parts of tackifying resin and 30 parts of an initiator cosolvent. The formula is benzene-free and has little smell, and the bonding capacity can be improved by 30-35% compared with that of common graft glue in the market.
Example two
The preparation raw materials of the benzene-free grafted rubber of the embodiment are composed of the following components in parts by weight: 60 parts of chloroprene rubber, 25 parts of methyl methacrylate, 2 parts of initiator, 3 parts of antioxidant, 7 parts of terminator, 10 parts of tackifying resin and 20 parts of initiator cosolvent. The formula is benzene-free and has little smell, and the bonding capacity can be improved by 27-30% compared with that of common graft glue in the market.
EXAMPLE III
The preparation raw materials of the benzene-free grafted rubber of the embodiment are composed of the following components in parts by weight: 80 parts of chloroprene rubber, 30 parts of methyl methacrylate, 5 parts of initiator, 1 part of antioxidant, 8 parts of terminator, 15 parts of tackifying resin and 40 parts of initiator cosolvent. The formula is benzene-free and has little smell, and the bonding capacity can be improved by 29-33% compared with that of common graft glue in the market.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
