Abstract
The invention relates to a manufacturing method of a one-time-moulding paper-attached glass steel product. The method includes following steps: (1) placing a decorative paper on a bottom of a mould, wherein the decorative paper comprises an original paper layer and a thermoset adhesive layer; and (2) adding glass steel in the mould and carrying out a compression moulding process at a certain temperature and under a certain pressure. Compared with a method in the prior art, the method has following advantages and beneficial effects: a one-time-moulding process is carried out through compression moulding; the product is quick to manufacture, is low in cost, is easy to produce in volume production, is free of toxic volatile substances and is safe and environment-protective.
Description
Technical field
The present invention relates to a kind of production method of one-shot forming paster glass fiber reinforced plastics product, particularly a kind of one-shot forming paster fiberglass bathroom wallboard, glass fiber reinforced plastic decorating board etc.
Background technology
Glass fiber reinforced plastics product, particularly, as products such as fiberglass bathroom wallboard, glass fiber reinforced plastic decorating boards, all needs to stick facing paper, to improve product appearance, beautifies environment for use.But the process that existing glass fiber reinforced plastics product pastes facing paper is substantially all to smear common adhesive at the back of facing paper, then facing paper is attached on fiberglass.But due in common adhesive, contain benzene, toluene etc. poisonous and be easy to volatilization material, thereby cause this fibre glass product manufacture peculiar smell large, unfriendly to environment, use before need a period of time to make its loose taste; And the easily inefficacy after often soaking water of common adhesive, thereby make facing paper come off.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, can one-shot forming, free from extraneous odour, bond effect is good, the production method of the one-shot forming paster glass fiber reinforced plastics product that can not lose efficacy.
The present invention addresses the above problem adopted technical scheme: the production method of this one-shot forming paster glass fiber reinforced plastics product comprises the following steps:
(1) facing paper is placed on to mold bottom, described facing paper comprises former paper layer and thermosetting adhesive layer; Thermosetting adhesive layer free from extraneous odour, does not have volatile toxic substance, safety and environmental protection; Thermosetting adhesive layer is bonded in former paper layer.
(2) in mould, add again fiberglass, then under uniform temperature and pressure, be pressed; After fiberglass is added to mould, once compressing in certain pressure and temperature, moulding is quick, and procedure of processing is few, makes its easy suitability for industrialized production, and process needs manual operation few, and automaticity is high, can be cost-saving.
Facing paper of the present invention is laminated construction, is from top to bottom wear-resisting blast resin bed, printing ink layer and printing original paper layer, thermosetting adhesive layer successively.Wear-resisting blast resin bed can improve facing paper surface effect, and printing ink layer is to have printed in advance needed pattern, and which type of pattern user needs just select which type of pattern, convenient and swift.
In step of the present invention (2), pressure is 80kgf/cm
2, temperature is 145 DEG C.
In step of the present invention (2), pressure is 80kgf/cm
2, temperature is 145 DEG C.Moderate pressure, is unlikely to too small and makes facing paper and fiberglass in conjunction with insecure, is also unlikely to excessive and increases energy consumption.Temperature can just in time make thermosetting adhesive melting layer and fiberglass combination at 145 DEG C.
Thermosetting adhesive layer of the present invention is unsaturated polyester (UP) layer.Unsaturated polyester (UP) is safe, and melt temperature is low, and caking property is good, particularly high to the bonding coefficient of fiberglass.
Fiberglass of the present invention comprises unsaturated polyester (UP), glass fibre, filler and auxiliary agent.
The present invention compared with prior art, has the following advantages and effect: by pressing one-time moulding, processing is quick, and cost is low, easily batch production; There is no poisonous volatile materials, safety and environmental protection.
Detailed description of the invention
Below by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment.
In the present embodiment, the production method of one-shot forming paster glass fiber reinforced plastics product comprises the following steps.
(1) facing paper is placed on to mold bottom, the surface of facing paper has thermosetting adhesive layer;
(2) in mould, add fiberglass again, use the pressurization of 1500T hydraulic press, pressure is 80kgf/cm
2, heating by steam-heating system, temperature is 145 DEG C, pressurize 210s(determines the dwell time according to the thickness of glass fiber reinforced plastics product, every millimeter of 60s dwell time); Facing paper and fiberglass are sticked together.Wherein pressure can be 70,90 or 100 kgf/cm
2, temperature can be 135 DEG C, 140 DEG C or 150 DEG C.
In the present embodiment, facing paper is laminated construction, is from top to bottom wear-resisting blast resin bed, printing ink layer, printing original paper layer and thermosetting adhesive layer successively.Bottom has thermosetting adhesive layer and can make facing paper and fiberglass form one under heated condition, save and originally need to spread upon the common adhesive on facing paper, avoid distributing of the free benzene of common adhesive, make facing paper and fiberglass be sticked together and just can directly use afterwards, free from extraneous odour.
In the present embodiment, thermosetting adhesive layer is unsaturated polyester (UP) layer.In the present invention, thermosetting adhesive layer can be the material of other types.
In the present embodiment, the printing ink layer on facing paper has printed needed pattern in advance.
In the present embodiment, fiberglass comprises unsaturated polyester (UP), glass fibre, filler and auxiliary agent.Increase the adhesive that unsaturated polyester (UP) can improve fiberglass and facing paper.
Above content described in this description is only made for the present invention illustrating.Those skilled in the art can make various amendments or supplement or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of description of the present invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
